Reaktionsschritte

This example demonstrates the transesterification reaction of dimethyl terephthalate with 1,3-propanediol using lanthanum t-butylacetylacetonate (otherwise known as tris(2,2,6,6-tetramethyl-3,5-heptanedionato)lanthanum or La(t-Bu-acac)3) as the transesterification catalyst (100 ppm La based on final polymer) to form bis(3-hydroxypropyl) terephthalate.
