Abstract:
Disclosed is a method for inhibiting the formation of by-products from dinitriles, such as the formation of cyclopentylideneimine (CPI) from Adiponitrile (ADN), comprising adding an effective amount of a Brønsted acid to the ADN. Also disclosed is a method of refining a dinitrile compound by distillation the method comprising the steps of: (a) supplying (i) a feedstream comprising the dinitrile compound and (ii) a Brønsted acid to a distillation apparatus; and (b) withdrawing from the distillation apparatus an overhead distillate stream comprising the dinitrile compound.

Claim (Index 10):
A method according to  claim 9 , wherein the Br\u00f8nsted acid is selected from phosphoric acids, sulfuric acid, C 4  to C 12  alkanesulfonic acids and C 7  to C 18  alkylbenzenesulfonic acids.
