摘要： A compound having a non-silanol hydroxyl group and a compound having a silanol group are subjected to dehydrative condensation in the presence of a compound of formula (1), (2) or (3): MXn (1) ZaSiR1bR2cR3d (2) CmF2m+1SO3Y (3) wherein M is a metal, n is the valence of metal M, and X is halogen or CmF2m+1SO3; a=1 to 4, b, c and d=0 to 3, a+b+c+d=4, R1, R2 and R3 are monovalent hydrocarbon groups, Z is halogen or CmF2m+1SO3; Y is H or HW, W is an amine NR4R5R6 or a nitrogen-containing heterocyclic compound, R4, R5 and R6 are H or monovalent hydrocarbyl groups, and m=0 to 10. The method is effective in silylating the hydroxyl group without generating a substantial amount of harmful by-products such as hydrogen chloride or triethylamine hydrochloride.

摘要： A contaminated Group III metal hydrocarbon is purified by providing an adduct of Group III metal hydrocarbon with a Lewis base in a solvent having a boiling point which is up to 200° C., but at least 30° C. higher than the boiling point of the Group III metal hydrocarbon, separating the solvent from the adduct, and heating the adduct for thermal dissociation, thereby releasing the Group III metal hydrocarbon in high purity form.
