Low cost and less toxic p-Toluene sulfonic acid catalysed ecofriendly and extremely rapid synthesis of aliphatic poly esters
Sivan Velmathi
Hereinwe demonstrate a rapid, environmentally benignmethod for aliphatic polyester synthesis by direct condensation of equimolar quantities of dicarboxylic acid and diol with commercially available, cheap, and less toxic p- Toluene sulfonic acid monohydrate as catalyst. In the presence of microwave irradiation at 230ï‚°C, Poly (butylenesuccinate) withMw= 2.50 x104was synthesized in 20 minutes. The methodology was also extended for the synthesis of various other aliphatic polyesters.
