另一篇文献中提到： Production of Fatty Alcohols Triacylglycerols, fatty acids, and esters can be reduced to aldehydes, alcohols, or hydrocarbons, the main application being the production of fatty alcohols. On a small scale, lithium aluminum hydride (in excess of stochiometric requirement) is a convenient reducing agent for the carboxyl group without affecting polyunsaturated chains. Industrially, catalytic hydrogenation is used and has been reviewed |

The different methods used in the production of fatty alcohols from various sources are (1) hydrolysis of wax esters using animal fats, (2) sodium reduction process using fats and oils, (3) Ziegler process using ethylene, (4) oxo process using olefins, (5) catalytic hydrogenation of fatty acids and methyl esters from fats and oils, and (6) direct hydrogenation of fats and oils. |
