Procedure

Three di-n-octyltin stabilizers (A,B,C) were prepared from this product by reacting the thiomalate with different proportions of di-n-octyltin oxide. In each instance, the thiomalate was warmed to 55° C, di-n-octyltin oxide added with stirring during a half-hour period, and water aspirator vacuum applied while warming to 80° C, then holding at 80° C for 2 hours to complete the removal of by-product water.
