Abstract
1,155,166. Splitting of acetals. MELLEBEZONS. 11 March, 1968 [29 March, 1967], No. 11835/68. Heading C2C. The splitting, by hydrolysis or alcoholysis, of an acetal or hemiacetal is effected using as a catalyst a sulphonic ion exchange resin, e.g. of the polystyrene sulphonic type, in its acid form. The preferred temperature is from 60-140‹ C. The preferred pressure is from 1-12 atmospheresand should maintain the reaction medium in the liquid phase at the operating temperature. The hydrolysis process may be carried out in the homogeneous liquid phase by the use of a water-miscible solvent, e.g. the alcohol produced by the hydrolyse reaction. Examples hydrolyse methylol and a mixture of isomeric butyl butyrals and form methylol from formaldehyde dibutyl acetal.
