摘　　要：针对目前广泛使用的相转移催化法制备双-(γ-三乙氧基硅丙基)四硫化物工艺生产的产品色度问题,本研究发现了影响双-(γ-三乙氧基硅丙基)四硫化物色度变化的影响因素,总结出多硫化钠合成阶段的温度、产品合成阶段缓冲剂的加入、液碱及氯丙基三乙氧基硅烷的pH值组合和脱色阶段树脂和酸的使用等因素是通过影响反应体系中pH值从而对双-(γ-三乙氧基硅丙基)四硫化物产品的色度产生影响。Based on the current widespread application of phase transfer catalyst prepared double-(gamma-triethoxy silicon propyl)four sulfide process produces the product color problem,this study found that the affected double-(gamma-triethoxy silicon propyl)four sulfide the influence factors of colour change,sums up the temperature of the synthesis of sodium polysulfide stage,product synthesis stage buffer,liquid alkali and chloride propyl triethoxy silane combination of pH and decoloring stage is influenced by such factors as the use of resin and acid reaction system pH value by the double-(gamma-triethoxy silicon propyl)tetrasulfide affect the shade of the products.
