| Abstract: | Dibutyltin sulfide was synthesized by the reaction of sodium sulfide and dibutyltin dichloride,which is an intermediate product prepared by disproportionation reaction of tetrabutyl tin and tin tetrachloride. The structures of dibutyltin dichloride and sulfide were characterized by infrared spectroscopy. As a catalyzer,the catalytic activity and water-tolerant stability of dibutyltin sulfide was studied in pre-polymerization reaction of waterborne polyurethane and compared with that of dibutyltin dilaurate(... |
