DEFINITION

Classification: 585/461

Complexed, e.g., sludge, etc., or with additional extraneous organic agent:

(under subclass 459) Subject matter wherein the aluminum halide catalyst is described as being in a chemical complex with another material or wherein the reaction takes place in the presence of an organic agent, which may be a solvent, mass-action agent, promoter, etc., which does not contribute atoms to the final product.

(1) Note. The aluminum halide complex may be formed in the reaction of aluminum halide with the hydrocarbon or hydrocarbons present in the process, or the complex may be preformed initially.
