Process for the preparation of polyvalent alcohols

The invention relates to a process for the preparation of polyvalent alcohols by hydrogenation of an aldehyde. According to the invention said aldehyde is obtained by aldolisation reaction of an aldehyde containing an alpha hydrogen atom and having the formula R1CHO, or the mixture of said aldehyde...

description	The invention relates to a process for the preparation of polyvalent alcohols by hydrogenation of an aldehyde. According to the invention said aldehyde is obtained by aldolisation reaction of an aldehyde containing an alpha hydrogen atom and having the formula R1CHO, or the mixture of said aldehyde with a second different aldehyde having the formula or R2CHO, wherein R1 is selected from alkyl having 1-12 carbon atoms, cycloalkyl, aryl and aralkyl having 1-14 carbon atoms, and R2 is selected from H, alkyl having 1-12 carbon atoms, cycloalkyl, aryl and aralkyl having 1-14 carbon atoms, said aldolisation being carried out in the presence of a weak base anion exchange resin, and the hydrogenation being carried out in the presence of a solvent and a hydrogenation catalyst.
