1,4-Benzenedicarboxylic acid, 1-(2-hydroxyethyl) 4-methyl ester

Description:

1,4-Benzenedicarboxylic acid, 1-(2-hydroxyethyl) 4-methyl ester, commonly known as dimethyl terephthalate (DMT), 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, and a hydroxyethyl group attached to one of the esterified carboxylic acid groups. This compound is typically a colorless, crystalline solid that is soluble in organic solvents but has limited solubility in water. It is primarily used in the production of polyesters, particularly polyethylene terephthalate (PET), which is widely utilized in textiles and plastic bottles. The presence of the hydroxyethyl group enhances its reactivity and compatibility in polymer applications. Additionally, it exhibits moderate toxicity and should be handled with care, following appropriate safety guidelines. Its chemical properties, such as melting point and boiling point, are influenced by its molecular structure and functional groups, making it a significant compound in industrial chemistry.
