DEFINITION

Classification: 585/712

With removal of organic halogen contaminant:

(under subclass 709) Subject matter in which an organic compound containing halogen is removed from the alkylation product or from a hydrocarbon stream in said process.

SEE OR SEARCH THIS CLASS, SUBCLASS:

310+, for a process wherein an alkyl fluoride by-product forms the intermediate in a hydrocarbon synthesis, especially subclass 311 where the synthesis is stated to produce HF for reuse as a catalyst in the procedure.

710, for a process where an organic halogen by-product is decomposed to produce a halide catalyst material.

711, for a process where an organic halide is used as an alkylating agent.

723+, and 729, for a alkylation processes which use hydrogen halide catalysts, promoters, etc.
