A new method for producing a thioester group-containing organosilicon compound by a convenient reaction with dramatically improved workability generating reduced byproduct is provided. The method comprises reacting an organosilicon compound having a hydrolyzable silyl group and mercapto group with a carboxylic anhydride. Also provided are an organosilicon compound having a hydrolyzable silyl group, a thioester group, and carboxyl group in the same molecule capable of remarkably reducing hysteresis loss of the cured rubber composition; a compounding agent for rubber containing such organosilicon compound; a rubber composition prepared by blending such compounding agent for rubber; and a tire produced by using the cured rubber composition are also provided.
提供一种通过方便的反应生成减少副产物的硫酯基含有的有机硅化合物的新方法。该方法包括将具有可水解硅基和巯基的有机硅化合物与羧酸酐反应。还提供了一种具有同一分子中可水解硅基、硫酯基和羧基的有机硅化合物,能显著减少固化橡胶组合物的滞后损失;一种含有此类有机硅化合物的橡胶配方剂;通过混合此类橡胶配方剂制备的橡胶组合物;以及使用固化橡胶组合物生产的轮胎。
