1507419 Aluminium butoxide solutions STAUFFER CHEMICAL CO 30 Nov 1976 [15 Dec 1975] 49936/76 Heading C2C A stable solution of aluminium butoxides is prepared by reacting metallic aluminium with a mixture containing isobutyl alcohol (A) and n-butyl alcohol (B) in which the mole ratio A : B is from 1 : 1 to 20 : 1. The aluminium may be contacted with the vapour of the alcohols, or partly with liquid and partly with vapour. Activators (e.g. mercuric, ferric, stannic or cupric chloride, boron trioxide iodine or alkoxy alcohols) may be present. A solution containing 23-90 wt. per cent aluminium butoxides in a mixture of isobutyl alcohol and n-butyl alcohol in which the mole ratio of aluminium isobutoxide to aluminium n-butoxide is from 1 : 1 to 20 : 1 is claimed per se.
