METHOD FOR THE MANUFACTURE OF ALKOXYSILYL-CONTAINING THIOCARBOXYLIC ACID ESTERS

There is provided herein a method for the manufacture of alkoxysilyl-containing thiocarboxylic acid ester which comprises reacting a thioester with a mercapto-functional alkoxy silane and/or an alkali metal salt, an alkaline earth metal salt, a trisubstituted ammonium salt of an alkoxysilyl-functional thiolate which uses economical and readily available reagents, avoids the use of phosgene or thionyl chloride reagents and produces byproducts that may be recycled.

Method for preparing mercaptosilane coupling agent by using channel reactor

The invention provides a method for preparing a mercaptosilane coupling agent by using a channel reactor. In a solvent, a channel reactor is utilized to prepare the mercaptosilane coupling agent. The structural general formula of the mercaptosilane coupling agent is XmSiC3H6S(C=O)nY, wherein each X is independently alkyl group, alkoxy group, hydroxy group, R(OR')LO-, -ORO- or N(RO-)3, and at least one X is alkoxy group, hydroxy group or N(RO-)3; Y is hydrogen or alkyl group; R and R' are respectively independently straight-chain or branched-chain alkyl group; the average value of L is 1-30; m is 1, 2 or 3; and n is 0 or 1. The corrected diameter of the channel reactor channel is one micrometer to several centimeters; and the channel reactor is connected with an after-treatment device. The method solves the problems of long reaction period, poor stability, existence of impurity polymers and the like in the large-size reactor, and especially reduces the odor caused by the large-size reactor production.

METHOD FOR PRODUCING THIOESTER GROUP-CONTAINING ORGANOSILICON COMPOUND, THIOESTER GROUP-CONTAINING ORGANOSILICON COMPOUND, COMPOUNDING AGENT FOR RUBBER, RUBBER COMPOSITION, AND TIRE

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.
