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 22):
A method according to  claim 16 , wherein an effective amount of the Br\u00f8nsted acid is defined as from 5 to 5,000 ppm by weight, optionally from 5 to 1,000 ppm by weight, optionally from 10 to 500 ppm by weight, based on the total weight of the composition comprising the dinitrile and the Br\u00f8nsted acid.
