Abstract

A method for producing a composition containing compounds (A) and (B), wherein: an organosilicon compound represented by formula (3), an alkali metal cyanate represented by formula (4) and an amide compound represented by formula (5) are reacted with each other at 120° C. or less, thereby producing an organosilicon compound (A) represented by formula (1); and this organosilicon compound (A) is obtained in a composition that contains this organosilicon compound (A) and an organosilicon compound (B), which is a by-product of the above-described reaction and is represented by formula (2). (In the formulae, each of R1 and R2 is an alkyl group or the like; X is a halogen atom; M is an alkali metal; m is an integer from 1 to 10; n is an integer from 1 to 3; and k is an integer from 1 to 10.)
