Abstract
The reaction of 2,6-di-tert-butylphenol with allyl alcohol resulting in the formation of 4-(3-hydroxypropyl)-2,6-di-tert-butylphenol is implemented on industrial scale. Condensation of the product with phthalic anhydride leads to the formation of the corresponding diphthalate, which is the final commercial product. The stability of operation at all technological stages was achieved in course of industrial practice.
