Abstract
An organic silicon compound having a ketimine structure can be recovered at a high yield through a method for producing an organic silicon compound having a ketimine structure represented by formula (1), the method having a step for reacting an amino-group-containing organic silicon compound represented by formula (2) and a carbonyl compound represented by formula (3) in the presence of an inorganic adsorbent. (In the formulas, Reach independently represent a C1-10 alkyl group or a C6-10 aryl group, Reach independently represent a C1-10 alkyl group or a C6-10 aryl group, Rand Reach independently represent a hydrogen atom, a C1-10 alkyl group, or a C6-10 aryl group, n represents an integer of 1-3, and m represents an integer of 1-12.) (In the formulas, R-R, n, and m are the same as above.)
