Method for producing organic silicon compound having ketimine structure

A method for preparing an organosilicon compound having a ketimine structure, represented by the formula (1):

• wherein R1 is each independently a C1-C10 alkyl group or C6-C10 aryl group,
• R2 is each independently a C1-C10 alkyl group or C6-C10 aryl group,
• R3 and R4 are each independently hydrogen, a C1-C10 alkyl group or C6-C10 aryl group,
• n is an integer of 1 to 3, and m is an integer of 1 to 12,
• the method comprising the step of reacting an amino-containing organosilicon compound having the formula (2) with a carbonyl compound having the formula (3) in the presence of an inorganic adsorbent,
• wherein R1, R2, R3, R4, n, and m are as defined above, and
• wherein the inorganic adsorbent is at least one member selected from the group consisting of aluminum hydroxide, hydrotalcite, magnesium silicate, aluminum silicate, and aluminum oxide/magnesium oxide solid solution.
