Problems solved by technology

[0005] The neutralization, water washing, and dealcoholization of the traditional process are completed through three reaction devices, which have disadvantages such as high equipment cost, large floor space, and inconvenient operation.
In addition, the traditional dealcoholization uses dibutyl phthalate and alcohol with different boiling points, and the kettle body is heated to dealcoholize, and the dealcoholization efficiency needs to be improved

Abstract

The invention discloses a diisobutyl phthalate neutralizing, washing and dealcoholizing integrated reaction kettle comprising a kettle body. An alcohol outlet is formed in the top of the kettle body, the kettle body is provided with a steam inlet and a steam outlet, one of the steam inlet and the steam outlet is positioned on the upper portion of the kettle body while the other is positioned on the lower portion of the kettle body, a steam pipe is arranged in an inner cavity of the kettle body, and two ends of the steam pipe are communicated with the steam inlet and the steam outlet correspondingly. The diisobutyl phthalate neutralizing, washing and dealcoholizing integrated reaction kettle has the advantages of lower equipment cost, small occupied area, convenience in operation and high dealcoholizing efficiency.

Description

technical field [0001] The invention relates to the technical field of reaction kettles, in particular to a reaction kettle integrating neutralization, water washing and dealcoholization of diisobutyl phthalate. Background technique [0002] Diisobutyl phthalate, also known as diisobutyl phthalate (English name Diisobutylphthalate; phthalicaciddiisobutylester); 1,2-benzenedicarboxylic diisobutylester; 1,2-benzenediisobutylester Di(2-methyl-propyl) formate {1,2-benzonedicarboxylicacidbis(2-methyl-propyl)ester}; DIBP for short. Colorless transparent oily liquid, not volatile, slightly aromatic. Flammable and toxic. Molecular formula C16H22O4 [0003] Diisobutyl phthalate is slightly soluble in water, and can be mixed with cellulose acetate, cellulose acetate butyrate, nitrocellulose, ethyl cellulose, polyvinyl chloride, polyvinyl acetate, polyvinyl butyral polystyrene, etc. Compatible with resins, mainly used as plasticizers. [0004] The production process of diisobutyl ...
