Abstract 1. IN A PROCESS FOR EFFECTING THE HYDROGENOLYSIS OF A CARBOXY-SUBSTITUTED FEEDSTOCK CONSISTING ESSENTIALLY OF AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF CARBOXYALKANES, HYDROXYCARBOXYALKANES, DICARBOXYALKANES, AND EPSILON-CAPROLACTONE TO A CORRESPONDING HYDROXYMETHYL-SUBSTITUTED DERIVATIVE OF SAID FEEDSTOCK BY CONTINOUSLY PASSING HYDROGEN, ALONG WITH SAID FEEDSTOCK IN A LIQUID REACTION MEDIUM CONSISTING ESSENTIALLY OF SAID FEEDSTOCK AND WATER THROUGH A REACTION VESSEL MAINTAINED UNDER A HYDROGEN PRESSURE OF AT LEAST ABOUT 225 ATMOSPHERE ABSOLUTE AND AT A TEMPERATURE OF ABOUT 180*C. TO ABOUT 300*C. AND CONTAINING A SOLID CATALYST THE SURFACE OF WHICH CONSISTS ESSENTIALLY OF CATALYTICALLY ACTIVE METALLIC COBALT, THE IMPROVEMENT WHICH COMPRISES; MAINTAINING THE ACTIVITY OF SAID CATALYST AND ALSO MAINTAINING A COBALT COATING ON THOSE INTERNAL SURFACES OF SAID VESSEL WHICH ARE NORMALLY WETTED BY SAID LIQUID REACTION MEDIUM DURING THE COARSE OF SAID HYDROGENOLYSIS BY INTRODUCING INTO SAID REACTION VESSEL, ALONG WITH SAID FEEDSTOCK AND REACTION MEDIUM, AN AQUEOUS SOLUTION CONTAINING A COBALT SALT OF A LOWER CARBOXYLIC ACID WHEREBY SAID COBALT SALT IS REDUCED AND METALLIC COBALT IS DEPOSITED ON THE INTERNAL SURFACES OF THE REACTOR AND ON THE CATALYST,
IN A PROCESS FOR EFFECTING THE HYDROGENOLYSIS OF A CARBOXY-SUBSTITUTED FEEDSTOCK CONSISTING ESSENTIALLY OF AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF CARBOXYALKANES, HYDROXYCARBOXYALKANES, DICARBOXYALKANES, AND EPSILON-CAPROLACTONE TO A CORRESPONDING HYDROXYMETHYL-SUBSTITUTED DERIVATIVE OF SAID FEEDSTOCK BY CONTINOUSLY PASSING HYDROGEN, ALONG WITH SAID FEEDSTOCK IN A LIQUID REACTION MEDIUM CONSISTING ESSENTIALLY OF SAID FEEDSTOCK AND WATER THROUGH A REACTION VESSEL MAINTAINED UNDER A HYDROGEN PRESSURE OF AT LEAST ABOUT 225 ATMOSPHERE ABSOLUTE AND AT A TEMPERATURE OF ABOUT 180*C.
