Procedure

In a kneading drier, 4.27 kg of β-mercaptopropionic acid are added by spraying to 14.53 kg of dioctyltin oxide over a period of 6 minutes. The mixture thus obtained is heated at 60° C. for a period of 20 minutes with thorough mixing and under a pressure of 120 hPa (=120 mbar), during which the water of reaction formed escapes. The mixture is then cooled to room temperature while thorough mixing of the product is continued. Dioctyltin β-mercaptopropionate is obtained as a white free-flowing solid.
