Procedure

Approx. 360 g of ammonia were introduced into a solution of 1000 g of tin tetrachloride in 6650 g of isopropanol. Subsequently, the ammonium chloride was filtered off. An approx. 16% solution of tin tetraisopropoxide in isopropanol was obtained. At a temperature of 70° C., 352 g of N-methyldiethanolamine were added to 6208 g of this solution and the mixture was kept at 70° C. for 1½ h. An approx. 20% solution of the target compound in isopropanol was obtained. Reprecipitation in 1,4-butanediol with distillative removal of isopropanol under reduced pressure afforded the 20% partial solution in 1,4-butanediol.
