Abstract
A process for production of a selectively alkoxylated triol, which process comprises two or more Steps including the Steps of a) reacting a cyclic triol formal having one reactive hydroxyl group with an alkylene oxide or correponding glycol, which reaction yields a corresponding alkoxylated cyclic triol formal; and b) acidic hydrolysis of the alkoxylated cyclic triol in the presence of a triol, which hydrolysis yields a selectively alkoxylated triol having one alkoxysubstituted and two unsubstituted hydroxyl groups and formaldehyde, which formaldehyde reacts with the triol yielding a cyclic triol formal, whereby in Step b) yielded cyclic triol formal can be used for alkoxylation in Step a). A further aspect of the invention relates to an acidic hydrolysis of a hydroxysubstituted cyclic triol formal. The hydrolysis is performed in the presence of a triol and the hydrolysis yields a selectively hydroxysubstituted triol having one substituted and two unsubstituted hydroxyl groups and formaldehyde, which formaldehyde reacts with the triol yielding a cyclic triol formal.
