Device for making plasticizer DOTP

Abstract

The invention discloses a device for making a plasticizer DOTP. The device comprises a first reaction box, a motor and a second air outlet tube are arranged in a middle part of the upper surface of the first reaction box, two first heating tubes and a rotating shaft are disposed in the first reaction box, the first heating tubes are disposed on the left and right sides of the first reaction box, the output shaft of the motor is fixedly connected to the rotating shaft through the first reaction box, fixed axles are subjected to array distribution on the side surface of the rotating shaft, a second reaction tank is arranged on the right side of the first reaction tank, a first water pump is arranged on the upper surface of a second reaction tank, and a first connecting pipe is arranged at awater inlet of a first water pump. The device has a firm structure, is stable and durable, can be mass-produced, improves production efficiency, can reduce unit manufacturing cost, brings convenienceto the use, and can change a heat transfer mode, improves the mass and heat transfer during an esterification process, and removes the water in time during a production process.

Description

technical field [0001] The invention relates to the technical field of plasticizer DOTP, in particular to a device for making plasticizer DOTP. Background technique [0002] At present, in the production process of the plasticizer DOTP, due to the influence of unfavorable factors such as limited mass transfer and heat transfer in the esterification process, and failure to remove the reaction production water in time, the conversion rate in the esterification process will decrease and the reaction speed will be reduced. Slower, the batch time of product production is long, which is not conducive to the improvement of production efficiency and the reduction of unit manufacturing cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a device for making plasticizer DOTP, which has a firm structure, is stable and durable, can be produced in batches, improves production efficiency, and...
