Abstract

Regioselective oxidn. of glucoside I [R = CH2OH (II)] to glucosiduronate I (R = CO2Na) by oxygen using active carbon supported Pt was studied in a three phase stirred tank reactor. At the investigated reaction conditions the initial reaction rates were free from mass and heat transfer limitations. Aldehyde I [R = CHO (III)] was found to be a reactive intermediate. The data could be described by a reaction rate equation of the Langmuir-Hinshelwood type, corresponding to a rate-detg. step on the Pt surface involving two active sites. No distinction was made between the sites of chemisorption for oxygen and II. The rate equation was based on a reaction sequence with two reaction paths, the first involving the absorbed II and dominating at low pH, the second involving the II anion and dominating at high pH. The adsorption of III and of I (R = CO2Na) was found to be negligible. The surface was mainly covered with oxygen at low pH and with both oxygen and the II anion at high pH
