Hash oil techniques and solvents for non BHO hash oil?

[SkyHighLer]

I went to grab a standard funnel to try out with some fan folded/fluted filter paper, and found something far superior.

That's an old Champion juicer loading funnel, whatever it's make of, I assume nylon, it's impervious to most solvents.

The cone is spread wide for high capacity, there's excellent flow through the large drain hole, it stays in place, and fits a wide variety of beaker style vessels, even short ones without extending into the collected solution.

If there is similar lab product, I didn't see it.

Yeah, not all plastics are safe with solvents.

I'm looking at a glass funnel from where I buy most of my laboratory glassware.

I'll probably get a Buchner funnel as well seeing I'll try reduced pressure work later on.

 

[SkyHighLer]

Coming for testing is a stainless steel double wall insulated cold solvent extraction/filtration device.

Secura SS French press, $22.

The plunger doesn't extend to the bottom if you use the lid.


Other wise.....

To check whether I was just lucky scoring HPLC grade ethyl acetate easily and inexpensively, I just bought another four liter jug, this time through Amazon Marketplace.

This is the kind I bought a while ago on Ebay for another project and I was right I can't use it with Hexane.

Dow Corning High Vacuum Grease:

It's fine. A more likely problem if there is one is too much grease applied. Or the 204C rating is exceeded? Apiezon H has a 240C rating.

I don't plan on applying that much heat to be honest.

Water has the highest boiling point of any solvent I plan on using in making a Cannabis extract.
Even then, I will use a separatory funnel to get rid of it. So I'm very safe. As a matter of fact
I made over a liter of distilled water a few days ago and had no issues.

This morning I also received an email from Amazon suggesting I open an Amazon Business Account, so I applied, as the owner and head tech of NVR Solvent Analysis.

One day approval process, I'll know tomorrow.

 

[G.O. Joe]

You need to find the companies that sell to individuals and stick with their catalog, or at least form a LLC. One of my favorites has the 4 l HPLC grade for less than ACS at $74, but that's before at least $50 in shipping.

Most companies have this problem with residential addresses and residential customers, yet when shipped from the same big company through some intermediary in their name to your residential address, the problem magically goes away.

I played it out and now I know.

What irks me is Tedia out and out trolled me when I was searching for ethyl acetate at Amazon, created a product offering just for me, and flashed it like a whore.



To satisfy my curiosity I just bought this from eBay to check out, $55.99 plus $4.20 CA sales tax, free shipping and handling.

"Ethyl Acetate 99% - Technical Grade - Gallon (4 Quart Cans)

Ethyl acetate (systematically, ethyl ethanoate, commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3-COO-CH2-CH3. This colorless liquid has a characteristic sweet smell

(similar to pear drops) and is used in glues, nail polish removers, decaffeinating tea and coffee, and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol andacetic acid; it is

manufactured on a large scale for use as a solvent.

This item is in compliance with United States Postal Service Publication 52 guidelines.

This material is flammable (class 3 hazardous material) and is packaged accordingly to meet Fedex Ground guidelines and ships as a consumer commodity ORM-D.

Not a low boiler, but I couldn't resist, the other solvent in nail polish, butyl acetate.

Three quarts for $50 plus $9.49 shipping from Amazon, similar deal at eBay.

"Nail polish consists of a film-forming polymer dissolved in a volatile organic solvent. Nitrocellulose that is dissolved in butyl acetate or ethyl acetate is common."

"The most common (nail polish) remover is acetone. This can be harsh on skin and nails, and can also remove artificial nails made of acrylic or cured gel. A less harsh nail polish remover is ethyl acetate, which often also contains isopropyl alcohol. Ethyl acetate is usually the original solvent for nail polish itself.

Acetonitrile has been used as a nail polish remover, but it is more toxic and potentially carcinogenic. It has been banned in the European Economic Area for use in cosmetics since 17 March 2000."

Also ordered a liter of butanol/n-butyl alcohol.


Still avoiding acetone, MEK, and MIBK... already searched for MTBE, expensive with limited availability.

Anything is possible locally. There's usually something somewhere at a site that lets you know how they feel about residences. Strike's second book Sources is almost 20 years old and your Amico is in there - maybe something listed in CA still works out. pdf at bookzz.org or wherever if interested.

Must read for every member of this forum. The PDF download took a few minutes.

Butyl acetate
From Wikipedia, the free encyclopedia

n-Butyl acetate, also known as butyl ethanoate, is an ester which is a colorless flammable liquid at room temperature. Butyl acetate is found in many types of fruit, where along with other chemicals it imparts characteristic flavors and has a sweet smell of banana or apple. It is used as a synthetic fruit flavoring in foods such as candy, ice cream, cheeses, and baked goods. Butyl acetate is often used as a high-boiling solvent of moderate polarity.

The other three isomers of butyl acetate are: isobutyl acetate, tert-butyl acetate, and sec-butyl acetate.


Occurrence in nature

Apples, especially of the Red Delicious variety, are flavored in part by this chemical. The alarm pheromones emitted by the Koschevnikov gland of honey bees contain butyl acetate.

https://en.wikipedia.org/wiki/Butyl_acetate


Extremely sweet, and evaporates quickly. I'm tempted to give it a taste.


The packaging was impeccable, and the label nicely laminated.

 

[SkyHighLer]

Preliminary test of the butyl acetate.

About a 0.1g of flower tops crushed between my fingers, the seeds weren't included.

Soaked three times in about 2ml of butyl acetate, each time filtered through the same filter into the same collection glass.


To determine if there was green tint yet to be extracted I soaked twice more, this time using 99% isopropyl alcohol.

All the soaks were about ten minutes each. The butyl acetate was at about 65F, the isopropyl alcohol at room temperature.


The cannabinoid and terpene dissolving power of the butyl acetate was checked against 99% isopropyl alcohol by how quickly each dissolved some BHO, each took a moment, and then cut it completely without hesitation.


Pics of the end result tomorrow.

 

[SkyHighLer]

I put a fan on it this morning and the remainder blew off immediately.

Then I vacuumed it down three times with the cordial liquor glass at room temperature.

The fragrant odor of the butyl acetate still was coming through, though I'm sure raising the temperature to 115-120F during vacuum purge would make a significant difference, we'll see when I do an actual run.

The tint looks promising to me, a quick soak with ice cold solvent should help.



I intend on doing a preliminary test of ethyl acetate next.

What about Ethyl Acetate? Is that not a better thc solvent than any of the Simple Alkane Alcohols?

Ostensibly so!


Isobutyl alcohol and propyl acetate ordered.

Methyl alcohol is the better for THC extraction than ethyl acetate.

You posted this earlier.

I got 4L of methanol (aka Methyl Hydrate) for $10.49 and it's 99.9% pure at a local store.

 

[SkyHighLer]

Methanol is a FDA USP Class 2 solvent, my purpose is to expand the field of known to be effective Class 3 solvents.

From Cannabis Alchemy,

There are several solvents that work well. Their properties, and the advantages and disadvantages of each, are discussed below:

1. Methyl alcohol, methanol, wood alcohol (boiling point 64°C). This solvent is commonly employed and, if used correctly, does a fine job. Methanol is available at many pharmacies and in larger quantities at industrial chemical supply companies. It is also available as paint thinner, but it is seldom very pure in this form. Methanol fumes are toxic and explosive. Inhalation of these fumes makes one sick, with pronounced body ache. Continued inhalation of even small amounts may cause permanent damage. Any traces of the solvent remaining in the oil product will be hazardous to the consumer. Methanol evaporates at a uniform temperature (approximately 190°F) and does not extract a lot of the water-soluble tars, which are not psychoactive. A method for removing traces of the solvent will be discussed later.

2. Rubbing alcohol (most rubbing alcohol is 70% isopropyl alcohol and 30% water). There are several advantages to using isopropyl rubbing alcohol. It is available in many stores at a low price and is much less toxic and explosive than methanol. Unfortunately, because it contains water, many of the water-soluble, non-psychoactive substances are also extracted. The oil yield using rubbing alcohol is twice that of methanol, and is proportionally less potent. Water-soluble tars may also give the oil undesirable taste and burning qualities. If the oil is to be re-extracted later with a more selective solvent, however, it matters little what it is like at this point. The water in the mixture also causes it to evaporate at a much higher temperature than methanol. Once the alcohol is completely evaporated, the water that was in the solvent remains with the oil. This takes a long time to evaporate in a boiling water bath. An oil bath may be used. The temperature of the oil in the bath is kept slightly higher than the boiling point of water. Water that gets into the oil bath may spatter; this is a hazard.

3. Ethanol, ethyl alcohol, pure grain alcohol (boiling point 78.5°C). This is a very desirable solvent. It has extraction properties very similar to methanol, but is not as toxic. It is very difficult to obtain, however, as it is a major active ingredient in liquor and is heavily taxed. Pure ethanol may be produced from either liquor or fermented material. Denatured ethanol, which is available in hardware stores and pharmacies, contains non-removable poisons which evaporate at the same temperature as pure ethanol. This makes the ethanol unfit for drinking.

4. Petroleum ether (boiling point 30—60° C). Petroleum ether is a light solvent much more selective than any of the alcohols. Extracting with petroleum ether produces an oil that is twice as potent by weight as oil extracted with alcohol. The cannabis material may be extracted directly with ether but, due to petroleum ether’s highly explosive nature, the oil is first removed from the plant material with alcohol and then re-extracted with ether. This requires a much smaller amount of the dangerous solvent. Petroleum ether is usually available only through chemical supply companies.

"Class 2 residual solvents (Table 2) should be limited in drug substances, excipients, and drug products because of the inherent toxicities of the residual solvents."

"Class 3 residual solvents (Table 3) may be regarded as less toxic and of lower risk to human health than Class 1 and Class 2 residual solvents. Class 3 includes no solvent known as a human health hazard at levels normally accepted in pharmaceuticals. However, there are no long-term toxicity or carcinogenicity studies for many of the residual solvents in Class 3. Available data indicate that they are less toxic in acute or short-term studies and negative in genotoxicity studies."

I don't have any ethanol over 40% yet.

I think the easiest and cheapest way for me to get 90+% would be to buy vodka and distill away.

I could make 100% dry ethanol if I really wanted to. But it would be overkill for most uses.
