Abstract
Diesters of phthalic acid and saturated aliphatic C4-C10 alcohols are obtained by continuously feeding a monoester of phthalic acid and a saturated aliphatic C4-C10 alcohol, a water immiscible liquid hydrocarbon as carrier inert with respect to the esterification reaction and capable of forming with water an azeotropic mixture boiling below the boiling point of an azeotrope of the reactant alcohol and water, and an esterification catalyst, to the first of a series of reactors, the reaction being effected at the boiling point of the mixture, distilling the carrier and the water formed from the reaction system, decanting off the water from the condensate and returning the carrier to the first reactor, introducing the reaction solution from the first reactor to the second reactor within the series of reactors, supplying more of the carrier thereto and carrying out the reaction therein in the same manner as in the first reactor, and repeating the same operation, each successive reactor if more than two reactors are employed. Specified liquid hydrocarbon carriers are aromatic, alicyclic and aliphatic hydrocarbons. Specified esterification catalysts are strong mineral acids, AlCl3, ZnCl2 and other Lewis acids, e.g. BF3, and aromatic or aliphatic sulphonic acids. The reaction can be carried out in reactors with or without stirrers. The reaction temperature is preferably 100 DEG to 200 DEG C. Examples are given for the production of dibutyl phthalate and di-2-ethylhexylphthalate. Apparatus is described.
