Ibee's no expert on the subject of HCFC's, CFC's, and HFC's but he did amass alot of useable data enroute to the Egull Method...so the term "skilled in the art" used by chemists, becomes "skilleted in the art" for the clandestin kitchenstyle cookery
Jacked:The Two Chems solubility difference data may explain why one works better than the other.
The TCTFE(R113) can be used as a solvent meaning it is miscible in other solvents
The TFE(R143a) is a compressed gas that vaporizes too quickly at room temp and boils out of most liquids.
Same difference as R12(solvent) and R22(gas)
The dichlorodifluoroethane(R12) is what Ibee initially used in the Pre-Egull days. It was found to be a superior extraction aid than tetrachloroethylene.
Due to Ozone depleting substance phaseout, Aquistioning a suitable effective substitoot proved to be pretty tough as most of the available CFC and HFC OTC options were gasses and couldn't be contained in liquids.
Then along came tetra and The Egull Method as used by those "skilleted in the art
".
