(ν–OH) of carboxylic acids, phenols or alcohols, and adsorbed water (3331.96 cm−1). Furthermore, the vibrations corresponding to ν–C–H bonds of methyl and methylene groups can be found at 2918.73 cm−1. The vibrations corresponding to ν–C=O in carboxyl (–COOH) or carbonyl ...
Propylene and ethylene may be carbonylated to form carboxylic acid esters or carboxylic acids in the presence of a catalyst complex containing 1 mole of BF and 1 mole of a second complexing component. The carboxylic acid product or acid portion of the ester product has one more carbon atom th...
A 1H NMR analysis of the reaction product after removal of ether showed the quantitative conversion of carboxylic acids in the reaction mixture to the corresponding methyl esters. The GC–MS chromatogram is shown as Figure SD1 in the supplementary data. The mass spectra of five methyl ester ...

The present invention relates in general to the hydrogenation of carboxylic acids. In particular the present invention relates to a process for the hydrogenation of acetic and propionic acids in the presence of a catalyst comprising a noble metal of Group VIII of the Periodic Table of the Elements...
Acid derivatives are produced by reacting approximately equivalent amounts of acid mono-or di-halides with hydroxy, carboxy or peroxy compounds in the presence of water, an amount of an alkali metal o
of interest. However, the catalysts of this type which have been disclosed hitherto do not as yet completely satisfy all the requirements set, especially when they are used for the preparation of esters of α,β-olefinically unsaturated aliphatic carboxylic acids, such as, in particular, methyl ...
