The N,N,N′,N″-1,2,4,5-tetra(ethylhexanoate) pyromellitamide is found to be capable of both intermolecular aggregation and binding to small anions. It is synthesized by aminolysis of pyromellitic anhydride with ethanolamine, followed by a reaction with hex

Paragraph 0032; 0033, (2017/08/30)
The invention discloses a derivative of pyromellitic acid. The structural formula (I) of the derivative is shown in the specification. A preparation method of the derivative of pyromellitic acid comprises the steps as follows: (1) pyromellitic acid dianhydride and methanol are used as initial materials and subjected to a complete esterification reaction under the action of a catalyst to produce an esterification product; (2) the esterification product and amino alcohol react to produce an aminolysis product; (3) the aminolysis product and sulfoxide chloride react to produce the derivative (I) of pyromellitic acid under the action of NaCO3. The prepared derivative of pyromellitic can be used as a curing agent of an outdoor polyester powder coating, produced films have no pinholes and other defects on surfaces, and the derivative has excellent weather resistance.
