ABSTRACT:
Methods and systems for the production of phthalic acid diesters are described herein. The methods and systems incorporate the novel use of a high shear device to promote dispersion and mixing of a phthalic acid derivative with alcohol. The high shear device may allow for lower reaction temperatures and pressures and may also reduce reaction time with existing catalysts.
