What is the synthesis method of Bis [3- (Triethoxysilyl) Propyl] Disulfide
To make bis [3- (triethoxysilyl) propyl] disulfide, you can follow the following ancient method. First take 3-mercaptopropyl triethoxysilane, which is the key raw material. Place an appropriate amount of it in a clean reactor, which needs to be dry and oxygen-free to prevent impurities from interfering with the reaction with oxygen. Then, slowly add an appropriate amount of initiator, such as azobisisobutyronitrile, to the reactor. The amount of initiator needs to be precisely controlled. At least the reaction is difficult to start, and at most it may cause the reaction to go out of control. The reaction temperature is also crucial. Raise the reaction system temperature to an appropriate range, about 60-80 degrees Celsius, and maintain a constant temperature in a water or oil bath. At this temperature, the thiol group (-SH) in the 3-mercaptopropyl triethoxysilane molecule can undergo free radical reaction under the action of the initiator. The sulfur atoms in the thiol group of the two molecules of 3-mercaptopropyl triethoxysilane will combine with each other to form a disulfide bond (-S-S-), and then form bis [3- (triethoxysilyl) propyl] disulfide. During the reaction process, thin-layer chromatography or gas chromatography can be used to monitor. When the raw material peak is significantly weakened and the product peak is stable, the reaction can be regarded as basically completed. Subsequently, the reaction mixture is cooled to room temperature and the product is purified by vacuum distillation. The unreacted raw materials, initiators and other impurities are removed to obtain pure bis [3- (triethoxysilyl) propyl] disulfide. The whole process must be handled carefully and the procedures must be strictly followed to obtain the ideal product.
