<p>PURPOSE:To obtain inexpensively and easily the titled powder useful as an adsorbent, desiccant, water repellent or the like by hydrolyzing a specified organosilicon compound together with, optionally, a silicon compound having only a group which forms a hydroxy group upon hydrolysis in an organic solvent. CONSTITUTION:The titled powder having an average composition formula of formula III [wherein 1/4<=m<=2 and n=(4-m)/2] and a mean particle diameter <=1mu is obtained by dissolving an organosilicon compound having a group which forms a hydroxy group upon hydrolysis and an organic group having C directly bonded to Si, represented by formula I (wherein R is an organic group having a C atom directly bonded to a Si atom, X is a halogen and k<=3) (e.g., alkylhalosilane) and, optionally, a compound having only a group which forms a hydroxy group upon hydrolysis, represented by formula II (e.g., halosilane) in an organic solvent (e.g., toluene) and hydrolyzing the compounds.</p> |
