Isomerisation and alcohol. purer alternative?

    I have been using a recipe for hash oil very similar to the method outlined in Cannibis Alchemy- reflux with methanol/ethanol, isomerise,then separate with toluene...

    As with any alcohol method, this strips off a good bit of chlorophyll/waxes/etc that then have to be separated mechanically.etc..quack.quack.quack.

    ------------

    So the question is this: anyone had any luck refluxing/isomerising with a more polar solvent such as naptha, and thereby eliminating the required separation later on?

    Any reason that isomerisation wouldn't work with something other than alcohols?
     
  2. answered my own question:

    -PET soak/reflux for less time than normal alk method.
    -filter
    -isomerise. again for less time than alk.
    -distill off PET.

    **here there would be a couple ways to go:
    -ethanol wash if you are paranoid about any remaining trapped PET.
    -water wash if you are paranoid about any remaining trapped ethanol.

    I think the ethanol wash might be overkill. However, a water wash is probably a good idea- it seems to take a tiiiiny amount of 'impurities' out, and ensures a stable pH. A very light film on the water after separation, but that might just be a weak emulsion from the process, rather than actual water solubles. *shrug* distilled water is cheap.

    Using the more polar solvent would eliminate the tol/water separation from the process (i HATE toluene. its vile) and reduces the contact time, but i gotta admit- the low boiling point and high toxicity is a little scary, and warrants using a LOT more vigilance.

    *boooooom* or more realistically, a bad headache from handling the PET.

    disclaimer: don't try this method with more volatile solvents for the first time until you are VERY comfortable with the equipment/procedures using less dangerous solvents. Definite potential for 'undesired consequences'. Details left out intentionally.
