If the chromic acid oxidation is performed with stoichiometric oxidant in the presence of diethyl ether as co-solvent (a method introduced by H.C. Brown), the epimerization of l-menthone to d-isomenthone is largely avoided.
Apple cider vinegar isn't likely to be effective for weight loss. Proponents of the apple cider vinegar diet claim that drinking a small amount of apple cider vinegar before meals or taking an apple cider vinegar supplement helps curb appetite and burn fat. However, there's little scientific support for these claims.
In fact, there are many websites today that tout something called âthe apple cider vinegar weight loss diet.â Most state that the ACV diet requires you to drink small amounts of apple cider vinegar before each meal. Apple Cider Vinegar, by the way, is made by squeezing out the juice of an apple and fermenting it. First you crush the apple and collect the juice. The fermentation begins when sugar and yeast are added. There is then a second process which adds specific bacteria which converts the alcohol into acetic acid.
