Diester Chemicals was established in the year 2001 by an chemical engineer with 20 years of business experince, with vision to manufacture Di Methyl Phthalate.

The manufacturing process is based on state of art technology of pressurized esterification of phthalic anhydride with alcohol i.e. methanol. The technology was developed in five long years.

The main advantage of pressurized esterification in closed loop is high purity product along with negligible loss of alcohol in waste streams.

We are committed to highest levels of quantity control to maintain good quality products consistently to our valued customers.
