| titleOfInvention | Reactor for preparing diethyl carbonate |
| abstract | The utility model discloses a reactor for preparing diethyl carbonate, which comprises a shell, wherein the upper end and the lower end of the shell are respectively provided with an upper connecting flange and a lower connecting flange along the outer circumference of the upper end and the lower end of the shell, the upper end of the inner side of the shell is provided with an upper tube plate, the lower end of the inner side of the shell is provided with a lower tube plate, a plurality of membrane tubes are arranged between the upper tube plate and the lower tube plate, the upper end of the shell is connected with an upper end socket through the upper connecting flange, the lower end of the shell is connected with a lower end socket through the lower connecting flange, the top of the upper end socket is provided with a discharge hole, the bottom of the lower end socket is provided with a feed inlet, the side surface of the shell is provided with a permeate outlet, and the permeate outlet is connected with a vacuum pump; according to the reactor, the side surface of the shell is vacuumized, so that a reaction product methanol in the membrane tube is continuously pumped out through the membrane tube, the reaction is promoted to be carried out in the positive direction, meanwhile, the particle size of diethyl carbonate is larger than the pore diameter of the membrane tube and is remained in the membrane, the separation of diethyl carbonate and methanol is realized, and the conversion rate of raw materials is improved. |
