Non-toxic stabilizer for halogenated polymer

A method for making organotin halides of the formula R.sub.3 SnX, R.sub.2 SnX.sub.2, or RSnX.sub.2 by the redistribution of appropriate mixtures of organotin compounds in the presence of stannous fluoride as a catalyst.

Method for making organotin halides

Biocidal agents containing as the active ingredients a diorgano tin compound of the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, and R.sup.5 are various organic groups, (R.sup.3 + R.sup.4) may be oxygen, and X is oxygen or sulfur; methods for using such agents to kill bacteria and fungi, for example by treating a substrate such as wood or a textile with such agents; a method for making said diorgano tin compounds; and certain of said diorgano tin compounds as novel compositions of matter, are disclosed.
