Abstract: A process for separating, by distillation, a mixture consisting essentially of 3,3-dimethylacrolein and 3-methyl-3-buten-1-ol, wherein the mixture to be separated is distilled in the presence of water and glycerol, the 3,3-dimethyl-acrolein first being distilled off azeotropically with water and the 3-methyl-3-buten1-ol then being separated, as an azeotropic mixture with water, from the higher-boiling glycerol. It is also possible to isolate the 3,3-dimethylacrolein by distillation if the 3-methyl-3-buten1-ol is partially replaced by 3-methyl-2-buten-1-ol. The 3,3dimethylacrolein, which can be isolated in pure form by the process of the invention, is a valuable intermediate for the synthesis of natural substances such as citral, vitamin A and chrysanthemic acid.

Abstract: Stabilized polyolefin molding materials comprising:- (1) a polyolefin; (2) a stabilizer; and optionally (3) one or more conventional other auxiliaries or additives and containing certain 4-(m,m''-ditert.-butyl-p-hydroxyphenyl)-butyl- (2) compounds as stabilizers. The polyolefins exhibit better stability than prior art stabilized polyolefins.
