Question

Product of reaction between terephthalic acid and ethylene glycol

Answer 1

Its monomer , BHET can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct, or by transesterification reaction between ethylene glycol and dimethyl terephthalate with methanol as a byproduct ( Fig. 1-a).

Answer 2

. (particle size up to a few microns) depending on its crystal structure and particle size. Its monomer , BHET can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct, or by transesterification reaction between ethylene glycol and dimethyl terephthalate with methanol as a byproduct ( Fig. 1-a). Polymerization is through a polycondensation reaction of the monomers (done immediately after esterification/ transesterification) with water as the byproduct ( Fig.1-b). ...
