    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).
