PROBLEM TO BE SOLVED: To provide a method for easily producing high quality alkoxysilane without sublimating contaminant urea and urea hydroxide in the distillation of an alkoxysilane layer after separating an alcohol solution layer with urea and urea hydroxide dissolved therein when chlorosilane is reacted with alcohol in a presence of urea.SOLUTION: The method for producing organoxysilane represented by formula (3) comprises: reacting chlorosilane represented by formula (1) with alcohol represented by formula (2) in a presence of urea; removing hydrogen chloride generated by the above reaction, urea hydroxide produced by reaction of urea, and urea in a reaction system as an alcohol solution dissolved in alcohol in the reaction system from the system; and thereafter distilling an obtained organoxysilane layer with metal alkoxide added to the layer, where Rand Rare monovalent hydrocarbon groups, a is an integer of 1-3, b is an integer of 0-2, a+b is an integer of 1-3, and Ris a monovalent hydrocarbon group.SELECTED DRAWING: None |
