Method of Producing Lower Alcohols from Glycerol
A reactive-separation process converts glycerin into lower alcohols, having boiling points less than 200 DEG C., at high yields. Conversion of natural glycerin to propylene glycol through an acetol intermediate is achieved at temperatures from 150 DEG to 250 DEG C. at a pressure ranging from 1 and 25 bar. The preferred applications of the propylene glycol are as an antifreeze, deicing compound, or anti-icing compound. The preferred catalyst for this process in a copper-chromium powder.
