The oxidation step is followed by a step involving the hydrolysis of the reaction mixture obtained and, if necessary, a step involving the hydrogenation of the compound obtained at the end of the hydrolysis step. %G English %L hal-01787823 %U https://agroparistech.hal.science/hal-01787823 %~ AGROPARISTECH %~ INRA %~ AGREENIUM %~ AGROPARISTECH-ORG %~ AGROPARISTECH-SPAB %~ APT_SP %~ INRAE %~ GMPA
