Abstract
A process is disclosed for reducing the solidification tendency of a normally solid lower aluminum alkoxide having 2 to 5 carbon atoms in the alkoxide radical. One embodiment comprises the steps of adding the aluminum alkoxide and a specific phosphorus compound to a common solvent, and forming a solution; and then extracting the common solvent to form a stabilized liquid. The phosphorus compound has an unblended structural formula ##STR1## wherein X, Y and Z are selected from (a) alkoxy groups containing from one to 12 carbon atoms; (b) alkyl groups containing from one to 14 carbon atoms; (c) aryloxy groups containing from 6 to 12 carbon atoms; (d) alkyl-substituted aryloxy groups wherein an alkyl group containing from one to 14 carbon atoms is substituted for a hydrogen atom; (e) alkyl-substituted aryloxy groups containing from 7 to 26 carbon atoms; and (f) aryl-substituted alkyl groups containing from 7 to 26 carbon atoms. Preferred processing conditions and products thereby obtained are also disclosed.
