Separation of dimethylsilanediol from dimethylsilanediol containing diluted hydrochloric acid comprises distillative condensation of the diluted hydrochloric acid and separation of e.g. vapor containing cyclic polydimethylsiloxane

Method for separating dimethylsilanediol (I) from dimethylsilanediol containing diluted hydrochloric acid (A) comprises condensing (by distillation) (A) and separating a cyclic polydimethylsiloxane (in excess) containing hydrochloric acid free vapor and a linear alpha , omega -dihydroxypolydimethyls...
