Abstract
Unsaturated fatty alcohols with 6 to 22 C atoms can be produced by directly hydrating deacidified and/or non-deacidified glyceride oils containing monounsaturated and/or polyunsaturated, straight chain and/or branched-chain fatty acids having 6 to 22 C atoms in the fatty acid residue, by applying a 30 to 100-fold excess of hydrogen in a pressure range from 50 to 300 bars, at temperatures from 200.degree. to 400.degree. C., to zinc-chrome-catalysts of the spinel type, while largely preserving the olefinic double bonds and with formation of propane and 1,2-propylene glycol.
Claims11
A process for the production of an unsaturated fatty alcohol having from about 6 to about 22 carbon atoms which comprises contacting a deacidified or nondeacidified glyceride oil the fatty acid portions of which are at least monounsaturated and which have from above 6 to about 22 carbon atoms with from about 30 to about 100 molar excess of hydrogen in the presence of a zinc-chromium catalyst of the spinel type under a pressure of from about 50 to about 300 bar and at a temperature of from about 200.degree. C. to about 400.degree. C. to form said fatty alcohol, 1,2-propylene glycol, and propane;
- wherein the olefinic bonds of said fatty alcohol remain substantially unaffected.
