.~.~ With specified isomerizate purification or separation procedure
DEFINITION
Classification: 585/738
With specified isomerizate purification or separation procedure:
(under subclass 734) Subject matter wherein the effluent from the isomerization reaction is treated, usually by a series of steps, to improve its quality or purity in some way.
(1) Note. A mere nominal "recovery", or "separating" step is not sufficient to warrant placement of a patent herein.
(2) Note. The procedure may involve a chemical reaction but does not result in the net synthesis of a desired, recoverable hydrocarbon or other product.
SEE OR SEARCH THIS CLASS, SUBCLASS:
331, for a process wherein isomerization is followed by alkylation or alkyl transfer to produce a branched-chain paraffin product.
705, for a process which includes the removal of a catalyst component, e.g., aluminum halide, etc., from sludge.
