Isophthalate

Isophthalate is a type of polyester resin, specifically a type of dicarboxylic acid, that is used in the production of various types of plastics and coatings. It is derived from phthalic acid, and is characterized by the presence of two carboxyl groups (-COOH) located on the same side of the benzene ring.

Chemical Structure

The chemical structure of isophthalate consists of a six-carbon benzene ring with two carboxyl groups (-COOH) attached at the 1 and 3 positions. This arrangement is what gives isophthalate its name, as "iso" refers to the same side, and "phthalate" refers to the presence of the phthalic acid derivative.

Uses

Isophthalate is primarily used in the production of polyethylene terephthalate (PET), a type of plastic that is widely used in the manufacture of bottles, films, and fibers for clothing and other textiles. It is also used in the production of alkyd resins, which are used in paints and coatings.

Health Effects

Exposure to isophthalate can cause irritation to the eyes, skin, and respiratory tract. Long-term exposure can lead to more serious health effects, including damage to the liver and kidneys. As such, it is important to handle isophthalate with care, and to use appropriate protective equipment when working with this chemical.
