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

A method of making alkyl esters of polycarboxylic acids by reacting an alkaline salt of the acid and at least one halo-alkane so that the rate of conversion is limited to 35- 85% whereby no partial esters are formed.
