Abstract: A process prepares hydrosiloxanes using acid-modified aluminium silicate as equilibration catalyst, where pulverulent aluminium silicate is applied, with mixing, to a siloxane mixture that consists of at least two siloxanes and at least one SiH-functional siloxane. The acid-modified aluminium silicate is prepared in situ with addition of acid, and the resulting reaction mixture is allowed to react with further mixing in the sense of an equilibration.
