Low-cost Dual - (triethoxysilyl) Propyl] - Sulfide Synthesis And Industrialization

Our country is the most potential market of the organosilicon compounds, the organosilicon was listed that the nation encourages one of the development industries. Because of the high speed of the " green tire" market, the car with " green tire" increase with 20% speed annually, the demand of sulfur -containing organosilicon compounds is increasing quickly. The Si-69 was first industrialization in the German Degussa co. in 1977, applying to the rubber vulcanization of the synthetic rubbers and natural rubbers, it is still one of the important sulfur-containing organosilicon compounds up to now. The synthesis of CPTES was researched, and synthesis of Si-69 adopting the homemade raw material, choosing the craft route of the cheap raw material in price, synthesizing in low cost and high property, and the same time developed the different sulfur content of sulfur-containing organosilicon compounds A-1589 to satisfy customer's demand.Firstly, the synthesis of CPTES of industrialization technique development and the reaction conditions such as the crafts of the raw material, solvent, temperature are researched, the products are excellent quality and good function, and 94-95% yield.Secondly, a set of 100 tons annually Si-69 device is designed and developed and the optimal technological conditions are obtained based on the experiment and optimun of the technological factors on this devise. At the time the adoption of reuse of the filter liquor, and control the secondary reaction entities 95% yield and up recovery exceeding the design value by 90% and German Degussa CO. standard product quality.Thirdly, develop to try to produce the different sulfur content organismA;1589, a set of 30 tons annually device is designed and developed and the optimal technological conditions are obtained based on the experiment and optimun of the technological factors on this devise, the product replaces to import.Finally , the reduplicate experiments show the stabilization of technological process and the ideal level of output, quality and consumption. The low cost and high property Si-69 and A-1589, which are the valuable attempt the valuable attemptof small-scale organosilicon device in China, will be a novel type to compete in the market.
