ABSTRACT:
Diester compounds are prepared from imide/dinitrile compounds employing a vapor-phase hydrolysis of dinitrile compounds in the presence of alcohol, more particularly from branched dinitrile compounds, such as methylglutaronitrile or branched dinitrile compounds obtained as by-products in a process for the production of adiponitrile by hydrocyanation of butadiene.
