Butane Residue Test Results

Don't mind him. That's Blue Berry / Red Berry guy who gets banned every day.
Try hexane or naphtha to remove and alcohol to rinse away the residual hexane or naphtha.

I used Naphtha to clean the grit off my old guitar frets stuff works great.
I lnow a guy who used Naphtha for RSO… not kosher in my book!!

Doesn't Rick Simpson call for using naphtha to make RSO?
Rick Simpson recommends using a VPM grade of Naphtha, which stands for Varnish and Paint Makers.
The designation naphtha, doesn't tell what it is, only the boiling point range of the contents. One of the components sometimes used in the light naphtha boiling point range, is benzene, a known carcinogen.
I also note from the bp range of VPM naphtha, that it includes components with boiling points up in the heptane range, which makes them hard to purge below levels of concern without adequate equipment and washes.
We don't use it or recommend it for extractions, but it is a cheap way to cut to the chase with long chain petrochemical deposits.
Its residue is also far easier to remove with hot ethanol, than the ones in MO.
GW said it clearly, there is plenty of good reason to never use naphtha, please don't, if you would like a more refined version that is acceptable look into 30-60C boiling point petroleum either, as it is mostly pentane and avoids the benzene.
"Petroleum ether, also known as pether, benzine, VM&P naphtha (varnish makers' & painters'), petroleum naphtha, naphtha ASTM, petroleum spirits, X4 or ligroin, is a group of various volatile, highly flammable, liquid hydrocarbon mixtures used chiefly as nonpolar solvents. Chemically, it is not an ether like diethyl ether, but a light hydrocarbon.
Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene. It has a specific gravity of between 0.6 and 0.8 depending on its composition. The following distillation fractions of petroleum ether are commonly available: 30 to 40 °C, 40 to 60 °C, 60 to 80 °C, 80 to 100 °C, 80 to 120 °C and sometimes 100 to 120 °C. The 60 to 80 °C fraction is often used as a replacement for hexane. Petroleum ether is mostly used by pharmaceutical companies and in the manufacturing process. Petroleum ether consists mainly of pentane, and is sometimes used instead of pentane due to its lower cost.[1]"

Second distillation...
Thats NOT WATER in there! And you can see a yellow residue all around the edge. Its all baked on the collection pot....

Wow, i never really get anything on my second distill if i even do one(time is never my friend these days) from the canned butane i use. Thats not water huh? is it oily? Ive never had clear oil left behind, specially globs like that. What temp you distill at. Ive dropped down to 60F if i can. Takes longer but makes me feel like im only getting butane and up.

How did it smell after the second run?
Not as bad, really cleaned up the smell...
But I still slightly smell something that im not familiar with...
Jesus, and I had heard that they had apparently "cleaned up" their butane and started distilling before shipping. That looks like green spooge.
Makes me want to hit up refined hydrocarbon, I was planning on going with ecogreen, but that is just baaaaaaad.

If you got that in the recovery spool after two runs whats your tank look like now?

Was that a 30# tank KB?
I bought and received another case of Capital in an attempt to add more data to the above dilemma. I boiled off two cans into a bag, vacuum purged the bag, weighed it, and then boiled off another two cans into the same bag, vacuum purged the bag, weighed it, and then boiled off a final two cans into the bag, vacuum purged it, and weighed it. Here's the numbers,
The weight of the residue of the first two cans divided by two comes to 0.019g per can.
The weight of the residue of the second two cans divided by two comes to 0.024g per can.
The weight of the residue of the third two cans divided by two comes to 0.018g per can.
The total weight of the residue divided by six comes to 0.021g per can.
The residue was lightly tinted yellow, see the picture, and had a slight lingering chemical smell.
Capital N-butane #3 had 0.021g of residue (six cans shot to the same test bag, this is the result divided by six)
Capital N-butane, USA, 6.6oz/187g can, reads on the bottom "14183"
I'm not flying to Maine, but if Capital would like to come to my house I'd be glad to perform the test while they watch, it is what it is.
They are now being demoted on my Best to Worst Canned Butane list, my apology to those who bought Capital based on my initial test of their product, I still don't know exactly what the problem is, but it seems unique to Capital, and it's unacceptable, at least imo.

^^Sorry if you've answered this already but what are you using right now for runs?
Says 24# on the box
