Esterification of phthalic anhydride by alcohols in the presence of titanium bis(β-diketonates)

Conclusions In the esterification of phthalic anhydride by 2-ethylhexanol in the presence of titanium bis(-diketonates), the rate constants of the reaction increase with decreasing stability of the chelate. The relation of the rate constant of the reaction of phthalic anhydride with normal C₆-C₉ alcohols catalyzed by bis (acetylacetonato) dibutoxytitanium and butyl orthotitanate in a medium of the corresponding diesters is extremal in nature because of the different degree of hydrolysis of the catalyst during esterification.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1247–1250, June, 1989.
