Abstract: The present invention relates to a process for the production of carboxylic esters by reaction of carboxylic acids and/or carboxylic anhydrides with at least one alcohol selected from alkanols having at least 5 carbon atoms, cycloalkanols, and alkoxy-alkanols, in the presence of an acidic esterification catalyst. The invention further relates to the use of the resultant carboxylic esters as plasticizers or in a plasticizer composition for thermoplastic polymers and elastomers.

Abstract: The present invention relates to a process for preparing a terephthalic diester by reacting terephthalic acid with at least one alcohol, wherein terephthalic acid is suspended in the alcohol in a dispersing tank, the preliminary suspension is passed from the dispersing tank into a reactor and converted in the presence of an esterification catalyst to obtain a reaction suspension, a stream of the reaction suspension is drawn off from the reactor, passed through a heat exchanger outside the reactor and heated and the heated reaction suspension is recycled into the reactor, and water of reaction is distilled off together with the vapor as alcohol-water azeotrope, the vapor is at least partly condensed, the condensate is separated into an aqueous phase and an organic phase and the organic phase is at least partly recycled into the reactor.

Abstract: A chemical-mechanical polishing (CMP) composition is provided comprising (A) one or more compounds selected from the group of benzotriazole derivatives which act as corrosion inhibitors and (B) inorganic particles, organic particles, or a composite or mixture thereof. The invention also relates to the use of certain compounds selected from the group of benzotriazole derivatives as corrosion inhibitors, especially for increasing the selectivity of a chemical mechanical polishing (CMP) composition for the removal of tantalum or tantalum nitride from a substrate for the manufacture of a semiconductor device in the presence of copper on said substrate.
