Abstract: PROBLEM TO BE SOLVED: To obtain a novel sulfanylsilane that can reduce smell, are can impart low mixture viscosity, improved scorch safety, high elasticity and tensile strength and high abrasion resistance and is useful as an adhesion auxiliary agent for or an additive for reinforcement to rubber mixture to be used in the production of pneumatic tire, tire tread or the like. SOLUTION: This is a compound represented by the formula: X1X2X3Si-A-A- SiR1R2R3 (X1-X3 are each H, a 1-8C alkyl or the like; R1-R are each H, a 1-16C alkyl or the like; A is a 1-16C alkyl that may be substituted with a 1-4C alkyl, or the like), typically 3-triethoxysilyl-propylsulfanyl-trimethyl-silane. This compound is obtained, in the case that A is an alkyl, by allowing a corresponding compound of X1X2X3Si-A-A-SiR1R2R3 to completely react with a compound of the formula: ClSiR1R2R3 (trimethylchlorosilane or the like) in an organic solvent in the presence of a base under heating, then distilling off the solvent and separating the product from solid base hydrochloride by filtration.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject new compound consisting of a specific oligomeric organosilicon compound and useful as an adhesive auxiliary or a reinforcing additive in rubber composition. SOLUTION: This compound is expressed by formula I [R1 to R3 are each H, a 1-4C alkyl or the like; Z is an 0-6C alkylidene; (x) is 1-6; (n) is 1-150; ...means that Z may be bound to one or the other C atom and its free valence is occupied by H] (e.g. organosilanepolysulfane). The compound of formula I is obtained by reacting a compound of formula II (X is a halogen) with MSH or M2Sy [M is a metal ion; (y) 2-6] or M2S and S, optionally in a solvent (e.g. ethanol) at 20-150 deg.C under normal pressures or higher pressures up to 6 bar in the presence of a catalyst. In the 2nd objective rubber mixture containing the compound of formula I, preferably 5-10 wt.%, based on the quantity of a filler used, of the compound of formula I is used.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in high selectivity and in high yield under suppression of undesired side-reactions by adding a specific allyl compound to a specific silane in the presence of a specific catalyst under specific conditions. SOLUTION: The addition reaction of an allyl compound of the formula: H2C=CH-CH2X (X is Cl, Br, I or the like), for example, allyl chloride to a silane of the formula: R2R3R4SiH (R2-R4 are each H, a halogen, a 1-6C alkyl or the like) (preferably trichlorosilane) is carried out at 0-200 deg.C and at 200 millibar - 10 bar, preferably in the presence of a multielement catalyst supported on a carrier, for example, activated carbon, in which one of these elements is platinum, to give the objective three-functional compound (3- chloropropyltrichlorosilane). The other elements in the multielement catalyst are preferably Ti or the like and the molar ratios of the platinum to other elements on the carrier are preferably 0.05/1-20/1.

Abstract: PROBLEM TO BE SOLVED: To industrially produce a mercaptosilane from inexpensive raw materials at low cost in a high space time yield in a state that the post treatment of the crude product can be maintained as simply as possible and in a state that the apodictic amounts of troublesome by-products can be minimized. SOLUTION: This method for producing a silylalkylthiol comprises reacting a silylalkylsulfanylsilane with water. The silylalkylsulfanylsilane is obtained by reacting a bis-silylalkyl-polysulfane or a bis-silylalkyldisulfane with an alkali metal and a chlorosilane.
