DEFINITION

Classification: 570/219

Plural diverse reactions in separate zones:

(under subclass 216) Process wherein different reactions are carried out in different zones.This subclass requires that at least one different reactant is added in a latter zone.

(1) Note. Mere plural addition of more of the same ingredient in a subsequent zone, e.g., multistage halogen addition, etc., will not place a patent in this or indented subclasses.

(2) Note. While at least one reaction must produce compound as required by subclass 216, the other diverse reaction may be of any type, e.g., preparation of halogenating agent by chemical reaction.
