METHOD FOR PRODUCING ORGANIC SILICON COMPOUND HAVING KETIMINE STRUCTURE

To provide a method for producing, with high productivity, an organic silicon compound having a ketimine structure with high storage stability.SOLUTION: The present invention provides a method that uses an inorganic adsorbent to reduce a chlorine content of an amino group-containing organic silicon compound of formula (2) to less than 0.1 mass ppm and then reacting the same with a carbonyl compound to produce an organic silicon compound of the formula (1). (R1 independently represent a C1-C10 alkyl group or the like; R2 independently represent a C1-C10 alkyl group or the like; R3 and R4 independently represent H, a C1-C10 alkyl group or the like; n is an integer of 1-3; m is an integer of 1-12).SELECTED DRAWING: None 【課題】保存安定性に優れたケチミン構造を有する有機ケイ素化合物の、生産性に優れた製造方法を提供する。【解決手段】無機吸着剤を用いて式（２）のアミノ基含有有機ケイ素化合物の塩素原子含有量を０．１質量ｐｐｍ未満に低減したのち、カルボニル化合物と反応させて式（１）で表される有機ケイ素化合物を製造する方法。TIFF2023022908000015.tif17132TIFF2023022908000016.tif22132（Ｒ1は、独立して、Ｃ１～Ｃ１０のアルキル基等；Ｒ2は、独立して、Ｃ１～Ｃ１０のアルキル基等；Ｒ3およびＲ4は、独立して、Ｈ、Ｃ１～Ｃ１０のアルキル基等；ｎは、１～３の整数；ｍは、１～１２の整数。）【選択図】なし
