HYDROCHLORINATION FOR CONVERTING HIGH BOILING POINT RESIDUE OBTAINED BY DIRECT METHOD INTO MONOSILANE COMPOUND

摘要

PROBLEM TO BE SOLVED: To efficiently convert the subject high boiling point residue into a monosilane compound by brining hydrogen chloride into contact with the mixture of the high boiling point residue obtained by the reaction of an organic chloride with silicon metalloid with a silane compound in the presence of a catalyst composition. ;SOLUTION: This hydrochlorination method comprises mixing an organosilane compound of formula I [R is a 1-6C alkyl, an aryl, a 1-6C alkoxy, trimethylsily, trifluoropropyl; (m) is 1-4; (n) is 0-2; (m)+(n)=2 to 4] with a high boiling point residue obtained by the reaction of an organic chloride with silicon metalloid, and subsequently bringing the mixture into contact with hydrogen chloride in the presence of a catalytic amount of a catalyst composition effective for accelerating the formation of a monosilane compound from the high boiling residue at a temperature of 150-500°C and at a whole reactor gauge pressure of 689.5kPa to 34.5MPa (100-5000psi) to obtain the monosilane compound of formula II [(y) is 0-4; (n) is 0-3; (y)+(z)=0-4].;COPYRIGHT: (C)1998,JPO
