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 15):
A method according to  claim 14 , wherein the distillation apparatus comprises a plurality of distillation columns and wherein the Br\u00f8nsted acid is supplied to at least one of the distillation columns, optionally wherein the Br\u00f8nsted acid is supplied to each of the distillation columns.
