A method for production of trimellitic acid three Xin Zhi

The invention discloses a production method of trioctyl trimellate. In order to control the quality of a raw material trimellitic anhydride, nitrogen protection is used during a production process; a small quantity of titanate catalysts is added to completely carry out esterification reaction on the conditions that two-stage esterification reaction and the byproduct water generated by the reaction is removed, thus the synthesised product does not need to be neutralized or only needs to be neutralized with a small quantity of a neutralizer, which means that the product possibly reaches the standards of high-quality products in terms of indexes such as chroma and acid value without being absorbed and decolored by activated carbon, thus avoiding the influence on chroma due to the existence of active carbon micro-particles and the problems occurring in downstream applications of the product due to the addition of lots of the neutralizer and the residue of lots of salts in the product; and the given aftertreatment method can be carried out to solve the problem when the acid value of the product is slightly high due to the low raw material purity of trimellitic anhydride, or acid regurgitation and the like occurring in a process of adding water to destroy the titanate catalysts.

Method for producing aromatic acid esters through catalytic distillation

The invention discloses a method for producing aromatic acid esters through catalytic distillation. According to the method, aromatic acid and low-carbon alcohol are used as raw materials, and a course of generating the aromatic acid esters and a course of separating and distilling products through a reaction in a catalytic distillation tower are performed at the same time, so that a technological process is simplified. According to the technique of the method disclosed by the invention, a manner of extracting aromatic ester products from the middle part of a distillation segment is adopted, and aromatic ester products with high purity are directly obtained. The method is high in universality, and is suitable for preparing aromatic acid including benzoic acid, phthalic acid, methyl benzoic acid and the like into high-purity aromatic esters. Compared with a conventional aromatic acid ester preparing technique, the method disclosed by the invention has the advantages of being simple in flow, few in by-products, low in operating cost, light in product color, high in product purity and the like.

Manufacture of alkyl esters of polycarboxylic acids
