Hydrolysis of sucrose by conventional and microwave heating in stirred tank reactorPlazl, Igor ; Leskovšek, Saša ; Koloini, Tine, 1940-2008The reaction kinetics of the hydrolysis of sucrose to fructose and glucose under catalysis by the strongly acidic cation-exchange resin Akmberlite 200 C in R-H form was investigated in thermal and ... microwave fields unsing a standard laboratory stirred tank reactor. The Teflon stirrer was used to eliminate the mass transport resistance and to assure homogeneous reaction temperature which was accurately measured by a specially designed Ni-Cr-Ni thermocouple. A Teflon water cooling coil was used for maintaining constant temperature in the reactor during microwave irradiation. The rate constants for the reaction at various temperatures were measured in experiments conducted in a water bath and the Arrhenius parameters were calculated. No rate enahancements or reductions of reacation time were observed when reactions were carried out under microwave irradiation at the same reaction temperature. It was shown again that the reaction kinetics in thermal and microwave fields did not differ.Source: The chemical engineering journal and the biochemical engineering journal. - ISSN 0923-0467 (Vol. 59, no. 3, 1995, str. 253-257)Type of material - article, component partPublish date - 1995Language - slovenianCOBISS.SI-ID - 18424581
