A process for preparing a polybutene amine composition comprises the steps of reacting a chlorinated polybutene with an excess of at least one mole of at least one type of an amine compound per mole of the chlorinated polybutene at a reaction temperature of at least about 100.degree. C.; neutralizing the reaction mixture with a base selected from the group of alkali metal and alkaline earth metal alkoxides and amides with formulation of one of an alcohol or ammonia, respectively; neutralizing any excess base with an acid that will produce essentially no water as a by-product; and recovering the polybutene amine composition, the process including the steps of removing the alcohol or ammonia in a timely fashion; and removing excess of the amine compound.

A process is disclosed for the preparation of hydrocarbyl metal halides, such as alkyl tin chlorides, in which a reaction between the metal in its metallic state and a hydrocarbyl halide is catalyzed by a complex formed between a hydrocarbyl metal halide and a dihydrocarbyl sulfoxide. In the case of tin, for example, the complex may be represented by the formula:
