@SkyHighLer - impressive commitment to solvents! props! have you tried any of them? can they all be purged completely?

 

[mr_coughy]

logical extractors are made for home extracts and I've seen great results using Everclear & vac oven. there are two sizes and the owner is very knowledgeable, look em up on IG or online.

@SkyHighLer - impressive commitment to solvents! props! have you tried any of them? can they all be purged completely?

They all seem usable except for one, benzyl alcohol. Evaporates too slowly, I made note here,

https://www.icmag.com/ic/showpost.php?p=7910565&postcount=106

A small piece of paper towel soaked in it took twenty-four hours to be odor free when set out to evaporate on the kitchen counter.

Relative speed of evaporation will be established by a simultaneous watch glass test of all of them with a timer running and photos taken until the last plate is dry.

The watch glasses for that test shipped today. The much larger watch glasses for non-volatile residue testing already came.


None of them have a really offensive odor, except maybe the cyclohexane, and it's going to purge off easily. The others are just plain sweet to downright fruity, and most are GRAS food grade, the degree of final purging depends on how sweet/fruity you can take.


All are much safer for RSO than naphtha or Coleman fuel.


David Hoye asked for my input on updating Cannabis Alchemy, and that is the goal, an updated solvent list.

 

[troutman]

All of the are safer for RSO than naphtha or Coleman fuel.

Coleman fuel could be used to get a certain solvent or two.
If you have the proper equipment and know what you're doing.
Using it as if off the store shelf would be sad.

Myself, I think I only need ethanol now for final rinsing and/or purging. I'm just debating buying a large bottle
of vodka and distilling vs getting a glass carboy for fermenting a sugar wash and making my own. Fermenting
would be more work. But would be cheaper in the long run and I could make all I want.

Amazon

Amazon shipped me a can of MG Chemicals butyl acetate today. They say a can of MG Chemicals ethyl acetate will go out tomorrow, three cans of MG Chemicals dimethyl carbonate from them arrives today.

https://www.amazon.com/gp/product/B06XSKQR94/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1


The MG Chemicals' cans of all three say Produced in Canada, can't you get their products up there?

Esters are easy to make if you're scientifically inclined.

There's videos of regular people making them on YouTube.

Dimethyl carbonate, $22/quart.

"Dimethyl carbonate (DMC) is an organic compound with the formula OC(OCH3)2. It is a colourless, flammable liquid. It is classified as a carbonate ester. This compound has found use as a methylating agent and more recently as a solvent that is exempt from the restrictions placed on most volatile organic compounds (VOCs) in the US. Dimethyl carbonate is often considered to be a green reagent.

Solvent
In the US, DMC was exempted under the definition of volatile organic compounds by the U.S. EPA in 2009. Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone, tert-butyl acetate, and parachlorobenzotrifluoride. DMC has an ester or alcohol like odor, which is more favorable to users than most hydrocarbon solvents it replaces. DMC has an evaporation rate of 3.22 (butyl acetate = 1.0), which slightly slower than MEK (3.8) & Ethyl Acetate (4.1) and faster than toluene (2.0) & isopropanol (1.7). DMC has solubility profile similar to common glycol ethers, meaning DMC can dissolve most common coating resins except perhaps rubber based resins. Hildebrand solubility parameter is 20.3 Mpa and Hansen solubility parameters are: dispersion = 15.5, polar = 3.9, H bonding = 9.7. DMC is partially soluble in water up to 13%, however DMC is hydrolyzed in water based systems over time to methanol and CO2 unless properly buffered. DMC can freeze at same temperatures as water, it can be thawed out with no loss of properties to itself or coatings based on DMC.

Safety
DMC is a flammable liquid that has a flash point of 17 °C (63 °F), which would limit its use in consumer and indoor applications. DMC is still safer than acetone, methyl acetate and methyl ethyl ketone from a flammability point of view. DMC has a recommended industrial exposure (REL) limit of 100 ppm by inhalation over an 8 hour work day, which is similar to a number of common industrial solvents (toluene, methyl ethyl ketone). Workers should wear protective organic vapor respirators when using DMC indoors or in other conditions where concentrations exceed the REL. DMC is metabolized by the body to methanol and carbon dioxide, so accidental ingestion should be treated in the same manner as methanol poisoning."

Just taking some last final steps before I start extracting.

It's the 1st time I do decarboxylation and the aromas are like a big herb factory.

I'm going to go with 110 °C [230 °F] for 110 minutes for my decarb temp and time
protocol which seems to be the best according to the following scientific article.

Those on this list I don't have, or have on order are either on the DEA watch list, form peroxides, have a disagreeable odor, are way too high priced, or are just plain unobtainium to us common folk. I didn't bother with heptane because it's similar to the pentane I've already purchased.

FDA USP <467> Residual Solvents

Solvents in Class 3 (Table 3) may be regarded as less toxic and of lower risk to human health. 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 solvents in Class 3. Available data indicate that they are less toxic in acute or short-term studies and negative in genotoxicity studies. It is considered that amounts of these residual solvents of 50 mg per day or less (corresponding to 5,000 ppm or 0.5 percent under Option 1) would be acceptable without justification. Higher amounts may also be acceptable provided they are realistic in relation to manufacturing capability and good manufacturing practice (GMP).

a glass carboy for fermenting a sugar wash

5 gallon buckets work great.

the DEA watch list

Really don't worry about that seriously transactions below 50 gallons are unregulated - even above that the DEA probably doesn't really care as long as you don't export it.

There is a book you may find interesting if you don't know it Purification of Laboratory Chemicals. It has to be one of the most common professional chemistry reference works. I have editions 4, 5, and 7 and often prefer the earliest, but a newer edition double in size and full of references is more desirable for most chemists.

The first two chapters is a collection of what the bench chemist already knows about the subject and is covered in more detail perhaps in textbooks - this book is bought for the last, larger part covering the individual common chemicals.

Good luck on whatever it is you have planned. Hope you've already maxed out your IRA allowance for the year.

 

[SkyHighLer]

If you're just purchasing a few chemicals from a vendor, and your order includes small quantities of MEK and/or MIBK I wouldn't worry about it, but the Feds could use the info if they have other suspicions.


"DO LAB STORES REPORT CHEM SALES?

No! They are businesses just like any other. They sell products and have hundreds or thousands of customers. They have only one set of restrictions: the little yellow sheet of List I and List II chemicals. These are the only marked products they are aware of.

I have point-blank asked many, many lab store owners what they do about purchases of List I and List II chems. They were all very forthcoming their answers. The answers were always the same. The lab stores of the United States have only two contingencies:

(1) They simply refuse to sell List I and List II chems.

(2) Those that do sell List I and List II chems keep records on file of the purchases for inspection by the DEA or State Narcotics.

Do the lab stores call the DEA or State Narcotics when a List I or List II purchase is made? No. Absolutely not. The lab stores tell me that they do only what is required of them by law. And that is to file away the particulars of the sale for on-site inspection by narcotics agents (this usually occurs every 1-3 months), or to mail off copies of the List I and List II purchases to the DEA every other month.

Yes, folks, that is the extent of the scrutiny that is placed on you by the chemical sales agents of this country. Any other chemical purchase is fair game. And why shouldn't it be? All chemicals aside of the List I's are perfectly legal to purchase and own! You may continue to waste time conjuring up mystery conspiracies that do not exist. But I'm telling you to stop. It is all up to the DEA to determine what sales are suspicious. The lab stores and chern companies don't have a clue."

I just make my own from sugar. A gallon costs about £20 to make. I distil it 3 times which gets me to 96% which works fine but I can get it to 100% just by storing over Zeolite. I recover the alcohol by distilling again after the dip. Freeze the alcohol first and no chlorophyll in the extract un less you dip for ages which is pointless. I have a portable vape and it runs great on the extract with just enough alcohol left in it to get the right viscosity. No taste of alcohol and the vape coil lasts a lot longer and doesn't get gunged up. It does add a faint cool, astringent effect to the vape I enjoy too. I tried other stuff like glycol which was just gross on every level.

 

[troutman]

I have made a little alcohol last Fall using corn sugar which I bought from a health food store.
It ferments very clean compared than regular table sugar and isn't very expensive either.
For yeast, I got the common EC1118 Lalvin wine yeast from a local brew place.

I dropped my glass gallon fermenter last year and it made a sticky mess.

Time to get a new and bigger one and be more careful.

Full array of pictures showing how Right Price Chemicals properly packages their shipments. I had to sign for it at the door.

2,2,4-Trimethylpentane, also known as isooctane or iso-octane evaporates extremely fast. Leaves a piece of paper towel completely dry in seconds, all the way to the point of zero odor. And this does have odor, contrary to the Wikipedia entry, though it's very subdued and mellow compared to gasoline.

Top notch solvent, I'm very happy I have another four liters coming.

I was checking to see if the the old standard source of hexane, Bestine Solvent and Thinner was still available, and ended up buying four quarts of tech grade hexane for $65.

Still avoiding, MEK and MIBK, it bothers me that MEK is so hard on plastics, not something I want around unless necessary, and I don't want to take responsibility for promoting something I'm uncomfortable with myself. I'm trying to make a purchase of MTBE from a mid size house in Texas, if that goes through I may order some MIBK from them.

I'll post up pics when the anisole arrives today.

I got my N-Hexane from an OTC product.

I should have said I was checking for the old standard source of heptane, Bestine Solvent and Thinner... not hexane.

And what's worse, I bought hexane, meaning to buy heptane. I'm trying to cancel the hexane order now.
