1,4-Benzenedicarboxylic acid, 1,2-ethanediyl bis(2-hydroxyethyl) ester

Description:

1,4-Benzenedicarboxylic acid, 1,2-ethanediyl bis(2-hydroxyethyl) ester, commonly known as diethylene glycol bis(2-hydroxyethyl) terephthalate, is an organic compound characterized by its ester functional groups and aromatic structure. It features a benzene ring with two carboxylic acid groups at the 1 and 4 positions, which are esterified with diethylene glycol. This compound is typically a colorless to pale yellow liquid with a moderate viscosity. It is soluble in water and various organic solvents, making it versatile for applications in the production of polyesters and as a plasticizer. The presence of hydroxyl groups enhances its reactivity, allowing it to participate in polymerization processes. Additionally, it exhibits good thermal stability and resistance to hydrolysis, which are beneficial properties for industrial applications. Due to its structure, it can also impart flexibility and durability to polymeric materials. Safety data should be consulted for handling and exposure guidelines, as with any chemical substance.
