Isooctyl acrylate production process with oil phase and water phase separation device

Abstract

The invention discloses an isooctyl acrylate production process with an oil phase and water phase separation device, and belongs to the technical field of isooctyl acrylate production processes. The device comprises a neutralization kettle; elastic telescopic rods with the same structure are inserted into the left side and the right side of the top of the neutralization kettle; an oil-water separation net film I is arranged at the bottom of an inner cavity of a coalescing filter element; and an oil-water separation net film II is arranged at the bottom of the coalescing filter element. In theproduction process, a separation barrel is adopted after neutralization; a solution enters the coalescing filter element through the influence of a guide block; a step motor is started and drives theseparation cylinder to rotate; under the action of centrifugal force, water in the solution flows downwards through the oil-water separation net film I and then flows to a water storage cavity througha water outlet pipe; and grease in the solution is adsorbed into a grease cavity by the coalescing filter element, so that oil phase and water phase separation is rapidly realized, the separation error and the labor intensity are reduced, and the overall work efficiency and the subsequent processing quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of isooctyl acrylate production technology, in particular to a production technology of isooctyl acrylate with an oil phase and water phase separation device. Background technique [0002] Isooctyl acrylate is mainly used as a soft monomer for the manufacture of acrylate solvent-based and emulsion-type pressure-sensitive adhesives. It is also used as the main monomer for the production of microsphere pressure-sensitive adhesives for note books. It is also used in the manufacture of coatings, plastic modifiers, papermaking and leather processing aids, fabric finishing agents and other products. The existing isooctyl acrylate will undergo a neutralization step during the preparation process, and the neutralized solution will be separated into an oil phase The oil phase and the water phase need to be separated. Most of the existing separation tanks are used to control the closing of the valve through the manua...

It is also used in the manufacture of coatings, plastic modifiers, papermaking and leather processing aids, fabric finishing agents and other products. The existing isooctyl acrylate will undergo a neutralization step during the preparation process, and the neutralized solution will be separated into an oil phase The oil phase and the water phase need to be separated. Most of the existing separation tanks are used to control the closing of the valve through the manual observation of the pipeline lens, so as to realize the work of oil entering the oil storage tank and water entering the water storage tank, which is easy to cause errors. , and the efficiency is low, the work intensity is high, and the subsequent processing quality is affected. Therefore, we propose a production process of isooctyl acrylate with an oil phase and water phase separation device
