Descripción general

Bis(2-hydroxyethyl) terephthalate belongs to the class of monomers known as diols or glycols. It is widely used to synthesize unsaturated polyester resins, polyethylene terephthalate (PET), and new biocompatible polymer systems. BHET can also be used as a plasticizer in polyester resins and rigid or flexible polyurethanes. Additionally, BHET and its derivatives have also been investigated for their potential use in biomedical applications, including drug delivery and tissue engineering, due to their excellent biocompatibility and mechanical properties.

Aplicación

Bis(2-hydroxyethyl) terephthalate canbe used as a monomer to prepare biodegradable aromatic-aliphatic copolyestersfor sustainable flexible packaging applications. The incorporation of BHET as abuilding block offers a promising approach to enhancing the properties ofbiodegradable plastics and promoting sustainable packaging solutions.

Enzymatic degradation of poly(ethylene terephthalate) (PET) is promising because this process is safer than conventional industrial approaches. Recently, a cationic PET hydrolase (PETase) was identified from Ideonella sakaiensis. Pre-incubation of a low-crystallinity PET film with anionic surfactants prior to initiating
