The multistep synthesis of novel bis-terephthalthioamides based on methyl esters amino acids (AAs) was proposed using conventional heating and microwave-assisted approaches. In fact, the comparative case study thionation new symmetrical diamides with Lawesson’s reagent (LR) performed. microwave-accelerated small-scale methodology successfully employed whole pathway from substrates (Gly, Ala, Va...

Random aliphatic-aromatic copolyesters synthesized from 1,4-butanediol, adipic acid, and terephthalic acid (BTA) have excellent thermal and mechanical properties and are biodegradable by mixed cultures (e.g., in compost). Over 20 BTA-degrading strains were isolated by using compost as a microbial source. Among these microorganisms, thermophilic actinomycetes obviously play an outstanding role a...

The synthesis of nylon 4,T from tetramethylenediamine and a terephthalic acid derivative was studied in a two stepprocess: prepolymerization, followed by postcondensation in the solid state (4 h, m C ) . The prepolymers were prepared by the nylon salt method, ester polymerization method, interfacial method, and a low temperature solution method. A maximum qinh of 1.52 was obtained. From a solut...
