Example Embodiment

[0037] Example 1

[0038] like Figure 1-8 , The present invention provides a method of producing DOP esterification esterification reactor, comprises a reaction vessel 1 vinegar, trap 2 is rotated, the supporting leg 3 and the buffer 4 into the cylinder, the outer surface of the reaction vessel 1 is connected to the activities for vinegar there trap 2 is rotated, rotation of the outer snare 2 is fixedly connected with a support surface of the buffer legs 3, the top of the reaction vessel 1 is provided with a vinegar feeder 4.

[0039] In the present embodiment, by the feeder 4 to the interior of the reaction vessel 1 was poured vinegar materials and additives, the reaction with the rotation of the two pairs of vinegar trap vessel 1 is rotated, to increase the flow of liquid inside, and then through the supporting leg 3 buffer shaking autoclave for reflecting a buffering vinegar.

Example Embodiment

[0040] Example 2

[0041] like Figure 1-8 As shown, in the basis of the first embodiment, the present invention provides a technical solution: preferably, the reaction acelline 1 includes a filter plate 13, and an over-water hole is opened on the outer surface of the filter plate 13, and the filter plate 13 is at top. The inner wall surface is fixedly connected to the pusher 131, and the rotary ball is fixed to the output of the pusher 131, and the outer surface of the rotary ball is fixed to the outer surface of the rotary ball is fixed, and the filter plate is fixed on the inner wall surface of the filter plate 13. The diameter diameter of the cross surface on the lower surface of the filter plate 13 is longer than the overwater hole on the top surface, and there is a guide 133 on the outer surface of the filter plate 13.

[0042] In the present embodiment, the top DOP vinegar is permeated by the overdrophone on the outer surface of the filter plate 13, and the sagging of the roll...

Abstract

The invention discloses an esterification reaction esterification kettle for producing DOP, and relates to the technical field of esterification reaction. The esterification kettle comprises a reaction vinegar kettle, a rotating ring sleeve, supporting buffer legs and a feeding cylinder, the outer surface of the reaction vinegar kettle is movably connected with the rotating ring sleeve, the outer surface of the rotating ring sleeve is fixedly connected with the supporting buffer legs, the feeding cylinder is arranged at the top of the reaction vinegar kettle, the reaction vinegar kettle comprises a filter plate, and water passing holes are formed in the outer surfaces of the upper side and the lower side of the filter plate. A pushing plate is fixed through a pulling ring and a fixing rope, the position of a buffer spring is fixed in cooperation with a connecting column, vinegar liquid on the outer surface is extruded in cooperation with an attaching soft layer, reverse pushing force is conducted on the attaching soft layer in cooperation with a capsule, and the beneficial effect that extrusion on the liquid surface is enhanced is achieved. The problem that discharging of internal impurities is affected due to the fact that the extrusion force on the liquid is too small is solved, and the effect of increasing extrusion on the internal impurities of the liquid is achieved.

Description

technical field [0001] The invention relates to the technical field of esterification reaction, in particular to a 7528 esterification kettle used in the production of DOP esterification reaction. Background technique [0002] Esterification reaction is a kind of organic chemical reaction, mainly the reaction of alcohol with carboxylic acid or inorganic oxyacid to generate ester and water, divided into reaction of carboxylic acid with alcohol, reaction of inorganic oxyacid with alcohol and reaction of strong inorganic acid with alcohol Three types, and the general reaction is slow, so concentrated sulfuric acid is often used as a catalyst, and polycarboxylic acid reacts with alcohol to generate a variety of esters. There are following problems at prior art: [0003] 1. Before the reaction of esterification, raw materials and concentrated sulfuric acid need to be added to the interior, and concentrated sulfuric acid is used as a catalyst. When concentrated sulfuric acid is i...
