Procedure

The same apparatus as that described in Example 1 was used. 1367 g (5 mols) of (2-methyl-3-chloropropyl)-cyclohexyl-dichlorosilane were introduced into the flask. At a starting temperature of 60° C., 300 g (5 mols) of n-propanol were added at a uniform rate over a period of 140 minutes. Thereafter the mixture was heated in 120 minutes to 145° C., accompanied by the escape of dissolved hydrogen chloride. The system was from this time forward evacuated to such an extent that it began to boil at a sump temperature of 145° C. An additional 300 g (5 mols) of n-propanol were introduced into the boiling reaction mixture over a period of 140 minutes. The reaction mixture was allowed to react for 35 minutes more, and then the crude product was worked up by vacuum distillation.
