ABSTRACT:
The instant invention relates to an improved process for the preparation of low molecular weight polyalcohols by the catalytic hydrogenation of a mixture of different low molecular weight hydroxy aldehydes, hydroxy ketones and optionally also polyhydric alcohols such as is formed from the autocondensation of formaldehyde (such a mixture will hereinafter be referred to as "formose"). The invention also relates to the use of these polyalcohols for the production of polyurethane resins.
