In the present work, six new aromatic polyesters (PE1-PE6) have been synthesized in high yields from the polycondensation between di- and tri hydroxyl monomers containing methylene unit, Schiff-base linkages and pyridine heterocyclic ring with 4-phenylenediacrylic acid and malonic acid using dibutyltin dilaurate as catalyst. The structure analysis of the polymers has been carried out by using FT-IR and 1H NMR spectroscopy. The monomers were characterized by FTIR and 1H NMR. FT-IR technique confirmed the esterification of di and tri hydroxyl monomers by the acid in all the polymers.

The invention discloses a method for synthesizing and purifying 1,1,1-tri(4-hydroxy phenyl) ethane, and belongs to the field of chemical synthesis. According to the method, a 1,1,1-tri(4-hydroxy phenyl) ethane (THPE) crude product is synthesized from phenol and p-hydroxyacetophenone by using hydrochloric acid as a catalyst and zinc chloride as a promoter, and is purified to obtain a pure product having a purity higher than 99 percent. The method is an economical and efficient method for producing the 1,1,1-tri(4-hydroxy phenyl) ethane with high reaction yield, and is also an efficient purification method for improving purity.
