Title:
PROCESS FOR MAKING 3-HYDROXYALKANENITRILES AND HYDROXYAMINOALKANES
Document Type and Number:
WIPO Patent Application WO2002012173
Kind Code:
A3
Abstract:
The present invention provides a process for making 3-hydroxyalkanenitriles comprising the steps of reacting an alkenylnitrile, wherein the alkenylnitrile is an alkenyl-2-nitrile or an alkenylnitrile which under reaction conditions isomerizes to form an alkenyl-2-Nitrile, in the presence of base with benzyl alcohol to form a 3-benzyloxyalkanenitrile adduct and then patrially hydrogenating the adduct in the presence of a trace amount of HC1 to form the 3-hydroxyalkanenitrile or fully hydrogenating the adduct for form a 3-hydroxyaminoalkane.
