Vector here in California SFV 818, Vector is $10 a can. Ronson had 24% iso-butane, 54%n-butane, 22% propane. Thanks irieie. But like myself and Eden say, propane is an excellent solvent of choice, but when used w a supercritical fluid extraction you only need 9 grams per pound of co2. So it makes sense what combination their putting together for people like us to really appreciate. Airgas has bulk gas. Isobutane is one of them and I do believe it's a CGA 350 or that may be hexane? Fuck Eden may hire a hit man and have me put down. Just blabbing all kind of game for any reasonably intelligent person to follow! So believe me when I say that I will lead an industry that is green by nature and apply it's main principles which is, to improve the quality of life w out any negative impact on the environment and one's health, is the main principle of green chemistry. Find uses for normally waste products, and put them to use, and make another product w it. That's exactly what supercritical carbon dioxide is, using the co2 which is a bi-product of making industrial ammonia, and before it sublimes to the atmosphere, we use it as a solvent that makes another product from a normally waste product(trim), so there isn't an increase in more greenhouse gas, we use what's there and it's ecologically friendly being used by plant life, giving us oxygen. It's just basic science.
