Abstract:
A process for preparing mixtures of linear organopolysiloxanes of the general formula 1R.sub.3 SiO--(SiR.sub.2 O).sub.n --SiR.sub.3 (1)in which organochlorosilanes of the general formula 2R.sub.4-y SiCl.sub.y (2)whereR is identical or different and is a hydrogen atom or an unsubstituted or substituted hydrocarbon radical having from 1 to 18 carbon atoms,y is 1 or 2, andn is 0 or an integer from 1 to 50,are reacted continuously in a closed circulation system with water which may, if desired, have been acidified with hydrochloric acid, where the HCl concentration in the hydrochloric acid discharged is from 18% to 24% by weight, said mixtures of linear organopolysiloxanes containing not more than 1% cyclic low molecular weight organopolysiloxanes.
