Abstract

1,274,505. 2,2 - Dimethylpropanediol - 1,3. BADISCHE ANILIN- & SODA-FABRIK A.G. 1 Oct., 1969 [2 Oct., l968], No. 48166/69. Heading C2C. 2,2-Dimethylpropanediol-1,3 is prepared by reacting hydroxypivalaldehyde with formaldehyde in a molar ratio of from 1:1À2 to 1À2:1 in the presence of an inorganic basic compound, e.g. NaOH, KOH or Ca(OH) 2 , and from 5 to 50% by weight of water (based on the weight of reaction mixture) at a temperature of greater than 65‹ C. The reaction may be carried out in an organic solvent, inert under the reaction conditions, and at most sparingly miscible with water. Mixtures containing the starting materials may be used, e.g. those obtained in the production of hydroxypivalaldehyde by aldolization in the presence of an inorganic base.
