Example Embodiment
[0018] Example 1:
[0019] The inner diameter of the reactor is Stainless steel tube, one in the center of the reactor The thermocouple temperature measuring tube is used to measure the temperature at any position between the inlet and the outlet of the reactor; the reactor is jacketed outside, and the reactor temperature is controlled by the high-speed flowing constant temperature water in the reactor jacket.
[0020] The citric acid and ethanol enter the reactor from the upper part of the isothermal fixed-bed integrating reactor for esterification reaction. The catalyst in the catalyst bed is 100ml. The reaction conditions are: alkyd ratio n (ethanol) / n (citric acid) = 2, empty Speed 1h -1 , The reaction pressure is 1MPa, the temperature is 60°C, and the reacted materials are discharged from the bottom of the reactor and enter the gas-liquid separator for separation. The unreacted ethanol is discharged from the upper part of the gas-liquid separator, and the triethyl citrate ...
Example Embodiment
[0021] Example 2
[0022] The reaction temperature was 40°C, and the others were the same as in Example 1. The resulting product number is KRB-2.
Example Embodiment
[0023] Example 3
[0024] The reaction temperature was 50°C, and the others were the same as in Example 1. The product number obtained is KRB-3.
