| titleOfInvention | Preparation method of sulfur bridge-containing reverse ester thiol methyltin |
| abstract | The invention discloses a preparation method of sulfur bridge-containing reverse ester thiol methyltin. The method comprises two stages: in a first stage, preparing mercaptoethanol oleate, and controlling the vacuum degree in a first reaction container to descend stepwise in a reacting process; and in a second stage, preparing sulfur bridge-containing reverse ester thiol methyltin by taking mercaptoethanol oleate obtained at the first stage as a raw material, dropwise adding a methyl tin chloride aqueous solution and a sodium sulfide aqueous solution into the mercaptoethanol oleate simultaneously, and undergoing a condensation reaction and a bridging reaction simultaneously to control sulfur atoms in sodium sulfide and tin atoms in methyl tin chloride to be connected in a sulfur bridge form. The preparation method is easy to implement, the problems of emulsification, saponification and the like in a production process can be solved effectively, and the productivity and production efficiency are increased; and meanwhile, the ratio of a sulfur bridge is controlled, so that the thermal stability of a product is in an optimal state. |
