PROCESS FOR PREPARING LOWER MOLECULAR WEIGH POLYHYDROXY COMPOUND

摘要

This invention relates to an improved process for the preparation of a mixture of various low molecular weight hydroxyaldehydes, hydroxyketones and polyhydric alcohols by the condensation of formaldehyde with itself. The essential feature of the improvement is that unpurified synthesis gases of the kind obtained from the large scale industrial production of formaldehyde can be used directly as the source of formaldehyde.
