PROCESS FOR PRODUCING COMPOUNDS COMPRISING NITRILE FUNCTIONS

摘要

The present invention relates to the production of compounds comprising nitrile functions and of cyclic imide compounds. It relates more particularly to the production of compounds comprising nitrile functions from compounds comprising carboxylic functions, advantageously of natural and renewable origin, and from 2-methylglutaronitrile (MGN) or a mixture N of dinitriles comprising 2-methylglutaronitrile (MGN), 2-ethylsuccinonitrile (ESN) and adiponitrile (AdN).

主权项

1. A process for the preparation of at least one nitrile of general formula I or respectively of at least one nitrile of general formula III and of at least the cyclic imide 3-methylglutarimide, the process comprising: reacting at least one carboxylic acid of general formula II or respectively at least one carboxylic acid of general formula IV with at least 2-methylglutaronitrile (MGN), wherein y is equal to 1 or 2; R represents a hydrogen atom, or one or more substituents.
