One of the features of the production method of the present invention is to use dioxane as a solvent. The use of dioxane has an advantage that a solvent-insoluble substance such as a gelation product is not formed during the hydrolytic condensation polymerization of trichlorosilane and organotrichlorosilane and at the time of the reaction with Earlcol. In the method for producing the compound of the present invention, the hydrolysis condensation polymerization temperature of trichlorosilane and organotrichlorosilane (hereinafter referred to as trichlorosilanes) may be a temperature at which dioxane crystals or the like are not formed in the reaction solution, It can also be carried out at a temperature from 0 ° C to the boiling point of dioxane or higher. In the usual case, the boiling point of trichlorosilane is 32 ° C., so that the temperature is preferably 10 to 50 ° C. during the initial stage of reaction with water.

Water to be reacted with trichlorosilanes may be added alone or diluted with a solvent which dissolves water without reacting with trichlorosilanes. When diluted and added,
It is preferable to use dioxane as a reaction solvent. The amount of water added is determined by the molecular weight of the silicon compound to be produced. When the alcohol has a low water / (trichlorosilanes) molar ratio of about 1 or less, there is no problem even if the trichlorosilanes and water are reacted and added after the hydrolysis polycondensation. Water / (trichlorosilanes)
When the molar ratio of the above is about 1 or more, if an alcohol is added as it is and reacted, a gel-like substance insoluble in the solvent is produced, or the obtained silicon compound becomes insoluble in the solvent during storage, so water / (tri When the molar ratio of (chlorosilanes) is about 1 or more, trichlorosilanes are reacted with water to carry out hydrolysis condensation polymerization, and then trichlorosilanes are further added, and then alcohol is added and reacted. The optimum amount of trichlorosilanes added later depends on the initial water / (trichlorosilanes) molar ratio. If the amount is too small, problems will occur in the stability of the produced silicon compound. If it is too large, the stability will be good, but the proportion of low-molecular weight compounds in the obtained silicon compound will increase.
