Bis(2-hydroxyethyl) terephthalate

Description:

Bis(2-hydroxyethyl) terephthalate, commonly referred to as BHET, is an organic compound characterized by its ester functional groups and its structure derived from terephthalic acid. It is a colorless, viscous liquid at room temperature and is soluble in water and various organic solvents. BHET is primarily used as a monomer in the production of polyesters, particularly polyethylene terephthalate (PET), which is widely utilized in the manufacture of plastic bottles, textiles, and films. The compound exhibits good thermal stability and mechanical properties, making it suitable for various applications in the polymer industry. Additionally, BHET can be produced through the glycolysis of PET waste, highlighting its potential in recycling processes. Its chemical formula reflects the presence of two hydroxyethyl groups attached to the terephthalate moiety, contributing to its reactivity and functionality in polymer synthesis. Safety data indicates that while BHET is generally considered to have low toxicity, appropriate handling and safety measures should be observed during its use and processing.

Bis(2-hydroxyethyl) terephthalate

CAS: 959-26-2

Bis(2-hydroxyethyl) terephthalate (BHT) is the glycol ester of terephthalic acid. It is a colorless, odorless, viscous liquid that is soluble in water and has a synergetic effect with polyethylene glycols. BHT is used to increase the stability of plastics and other materials against chemical degradation by inhibiting oxidation reactions. This compound can be prepared by reacting trifluoroacetic acid with ethylene glycol. The activation energy for this reaction is 28 kJ/mol. The reaction mechanism involves an intramolecular hydrogen bond between the hydroxy group on the 2-position of the terephthalate molecule and the carbonyl group on the 1-position. The high values are due to its ability to intercept radiation from UV light sources and gamma rays.
