General Description

Terephthalamide, also known as terephthaloyl dichloride, is a chemical compound commonly used in the production of high-performance polymers such as aramid fibers and polyimides. It is derived from terephthalic acid and isocyanates, and its main function is to act as a cross-linking agent to provide strength and stability to the polymers. Terephthalamide has heat and chemical resistance properties, making it ideal for use in applications such as aerospace, automotive, and protective clothing. It is also used in the production of electronic materials, adhesives, and coatings due to its high performance and durability.

Method for preparing terephthalamide from terephthalic acid

The invention discloses a method for preparing terephthalamide from terephthalic acid, which comprises the following steps: carrying out esterification reaction on terephthalic acid and alcohol, and discharging by-product water generated by the reaction out of the reaction system; introducing ammonia gas into the esterification liquid to be ammonolyzed, and carrying out ammonolysis reaction to obtain a reaction container (marked as a reaction container I) filled with ammonolysis liquid containing high-concentration ammonia gas; connecting the reaction container I with a reaction container (marked as a reaction container II) filled with a next batch of esterification liquid to be ammonolyzed, so as to recover excessive ammonia gas; and cooling the ammonolysis liquid containing the low-concentration ammonia gas in the reaction container I, conducting filtering, and washing and drying a filter cake to obtain terephthalamide. According to the invention, terephthalic acid is subjected to esterification and ammonolysis to produce terephthalamide, the main byproduct in the reaction process is water, and the green production concept is met.

Ru-based complexes as heterogeneous potential catalysts for the amidation of aldehydes and nitriles in neat water

Five novel heterogeneous mononuclear complex-anchored Ru(III) have been efficiently sono-synthesized and characterized by utilizing several analytical techniques. The assembled complexes could be utilized as effective, robust and recyclable (up to eight consecutive runs) catalysts for one-pot transformation of a vast array of nitriles and aldehydes to primary amides in H2O under aerobic conditions. Moreover, some unreported di- and tetra-amide derivatives were obtained also under the optimal conditions. The results of ICP/OES analysis demonstrated that there is no detected leaching of the recycled catalyst, which suggests the real heterogeneity of the present protocol. The present Ru-complexes exhibited superiority compared to other reported catalysts for amide preparation in terms of low catalyst load, short reaction time, low operating temperature, no hazardous additives required, and high values of TON (990) and TOF (1980 h11).
