Bis(2-hydroxyethyl) terephthalate (BHET) is an important compound produced from poly(ethylene terephthalate) (PET) cleavage. It was selected as the representative substance for the study of PET degradation. A bacterial strain HY1 that could degrade BHET was isolated and identified as Enterobacter sp...
BIS-2-HYDROXYETHYL TEREPHTHALATE PELLET AND METHOD FOR PRODUCING POLYESTER PROBLEM TO BE SOLVED: To provide pellets of bis-2-hydroxyethyl terephthalate (BHET) which solve the cause of a problem brought out in the light of using BHET, have good handling properties such as transportability, and can...
Crude bis(beta-hydroxyethyl) terephthalate (BHET) is purified by (1) dissolving in a hot aromatic solvent to a concentration higher than the saturation solubility of the ester at the apparat melting point (Tm) of BHET in the solvent; the solvent is at a temp. higher than Tm, (2) cooling...
Process to prepare bis (2-hydroxyethyl) terephthalate This invention refers to a process to prepare very high purity bis(2-hydroxyethyl) terephthalate, using waste polyethylene terephthalate (PET) as the starting product. More specifically, the process is used to prepare BHET through the re... P...
