【Abstract】 The catalytic hydrogenation of rosin was carried out in a high-pressure agitated autoclave (type FYX-2G), and a measurement system for temperature and pressure have been designed, so the temperature and pressure can not only be read on operation site, but also be transmitted remotely, the data collecting and processing can be finished by computer, and security of operation, quickness and accurate of record were obtained. The results shown that mass transfer of gas-liquid-solid phase surface was strengthened by using a blade-paddle and impulse double-deck complex stirrer, and at temperature 160℃, pressure 5.0 MPa and reaction time 70 min, the conversion of abietic-acid was up to 99.7% with Pd/C catalyst. The sampling equipment under high pressure was installed, and the experiment shown that this equipment can trace the changes of concentrations of reactants and products with reaction time on line in the course of reaction.更多还原
