Preparation of mixtures of methyltin trichloride and dimethyltin dichloride from stanic chloride and dimethyltin dichloride without catalyst and conversion to mixed methyltin mercaptide stabilizers

摘要

A process for making a mixed product of dimethyltin dichloride and methyltin trichloride by reacting dimethyltin dichloride with stannic chloride without catalyst. The mixed product is useful as an intermediate, without further purification, in the preparation of corresponding mercaptide stabilizer for vinyl chloride polymers.
