Process for the production of alkane polyols

A process for the production of alkane polyols and especially alkane triols where mono- and/or poly-epoxidized fatty acids and/or fatty acid esters and mixtures thereof, especially derivates of natural fatty acids, are reacted with short-chain alkane-carboxylic acids such as formic or acetic acids;...

Zusammenfassung:	A process for the production of alkane polyols and especially alkane triols where mono- and/or poly-epoxidized fatty acids and/or fatty acid esters and mixtures thereof, especially derivates of natural fatty acids, are reacted with short-chain alkane-carboxylic acids such as formic or acetic acids; and the ester alcohols produced are hydrogenated on a hydrogenation catalyst such as those containing copper chromite at elevated temperature and pressure. The maximum possible number of alcohols groups per molecule can be formed in this way thus producing alkane triols, for example, which are useful in cosmetic formulations as well as in polyurethanes.
