| 摘要 |
A PROCESS FOR PRODUCING AN ALKYLENE CARBONATE, WHICH COMPRISES REACTING AN ALKYLENE OXIDE WITH CARBON DIOXIDE IN THE PRESENCE OF A CATALYST IN A REACTOR TO OBTAIN A REACTION MIXTURE CONTAINING AN ALKYLENE CARBONATE, THE REACTOR COMMUNICATING WITH A PROCESS-SIDE CHANNEL OF A HEAT EXCHANGER THROUGH A PIPING TO FORM A CIRCULATION CIRCUIT,WHEREIN THE PROCESS IS CHARACTERIZED IN THAT IT FURTHER COMPRISES, DURING OR AFTER THE REACTION, FLOWING A PROCESS LIQUID THROUGH THE CIRCULATION CIRCUIT INLCUDING THE REACTOR AND THE PROCESS-SIDE CHANNEL OF THE HEAT EXCHANGER WHILE FLOWING A HEAT EXCHANGE MEDIUM HAVING A TEMPERATURE OF FROM 140°C TO 200°C THROUGH THE HEAT EXCHANGE-SIDE CHANNEL OF THE HEAT EXCHANGER, THEREBY MAINTAINING THE INNER TEMPERATURE OF THE PROCESS-SIDE CHANNEL AT 135°C TO 200°C.
