(57) [Summary] [Structure] Anhydrous sodium sulfide represented by Na 2 S and sulfur are reacted in a polar solvent under an inert gas atmosphere to obtain sodium polysulfide, which is then isolated. Of the sulfur-containing organosilicon compound represented by the following formula (2), characterized in that the halogenoalkoxysilane represented by the following general formula (1) is added thereto and reacted in an inert gas atmosphere. To manufacture. [Chemical 1] (In the formula, R 1 is a methyl group or an ethyl group, and R 2 is a carbon number of 1 to 1. 9 is a divalent hydrocarbon group, X is a halogen atom, and m is 1, 2 or 3. ) [Chemical 2] (In the formula, R 1 , R 2 , and m have the same meanings as described above, and x is an integer of 2 to 6.) Effect According to the present invention, a polysulfide structure is formed by a simplified method. A sulfur-containing organosilicon compound can be produced with high purity, and the obtained sulfur-containing organosilicon compound further improves the reinforcing property of a vulcanizable rubber composition supplemented with a natural or synthetic silicic acid substance such as slier. It can be suitably used as a reinforcing agent. |
