Abstract
Continuous process for obtaining dibutyl phthalates, by continuous esterification of the phthalic anhydride with a stoichiometric excess of butan-1-ol or butan-2-ol, under high pressure, without addition of esterification catalysts, characterized in that in a first in this step, the phthalic anhydride is reacted with 0.8 to 1.2 mol and then, in a second step, with another 1.3 to 2.0 mol of butanol, the pressure being adjusted so that the esterification mixture boils in both stages at a temperature between 150 and 250º c.
