Abstract: Preparing mixtures (A) of diesters (I) of phthalic acid (PA) with decanols (IIa) and tridecanols (IIb) by reacting PA, or its reactive derivatives, with a mixture of at least one each of (IIa) and (IIb).

Abstract: A process is described for preparing esters of an acid component selected from among polybasic C 4 -C 10 carboxylic acids and an alcohol component selected from among C 3 -C 12 alkanols or from among C 3 -C 12 alkanediols, the alkyl chain of which may have interruption by from 1 to 3 oxygen atoms, by a) heating at boiling point, in a reaction zone and in the presence of an esterification catalyst, a mixture essentially consisting of the acid component or of an anhydride thereof and of the alcohol component, b) using rectification to separate the vapor comprising alcohol and water into an alcohol-rich fraction and a water-rich fraction, and c) returning the alcohol-rich fraction into the reaction zone and conducting the water-rich fraction out of the process. The process is simple to carry out and permits rapid achievement of essentially quantitative conversion.

Abstract: The invention relates to a method for producing esters of an acid component chosen from the multibasic C4-C10-carboxylic acids and an alcohol component chosen from C3-C12-alkanols or -alkanediols whose alkyl chain can be interrupted by 1 to 3 oxygen atoms. Sad method comprises the following steps: a) a mixture consisting essentially of the acid component or an anhydride thereof and the alcohol component is heated to boiling in a reaction zone in the presence of an esterification catalyst; b) the vapours containing alcohol and water are separated into a fragment that is rich in alcohol and a fragment that is rich in water by rectification; and c) the alcohol-rich fraction is fed back into the reaction zone, while the water-rich fraction is extracted from the process. The inventive method is simple to carry out and allows the rapid adjustment of an essentially quantitative conversion.

Abstract: A method for removing esterification catalyst from crude plasticizer ester based on dicarboxylic acid and 8-13C alcohols, by treatment with aqueous alkali at 10-100 degrees C followed by separation of the hydrolyzed catalyst-containing aqueous phase under gravity, in which the crude ester is treated before or during phase separation with salts(s) of di- or multi-valent metal(s).
