Abstract: Isopropyl esters of carboxylic acids having up to 20 carbon atoms are prepared by passing propylene and the respective carboxylic acid continuously in parallel flow over an acid ion exchanger of the sulfonic acid type. The service life of the catalyst is greatly improved by adding a small amount of a strong mineral acid.

Abstract: 1. A process for the preparation of a glyoxylic acid ester by oxydehydrogenation of the corresponding glycolic acid ester in the gas phase over a supported catalyst in a tubular reactor, wherein the catalyst support consists of at least one cylindrical monolith, the monolith essentially having the same diameter as the reactor tube and containing channels 1 to 10 mm in diameter which lead from the inlet to the outlet of the reactor tube, and wherein 60 to 90% of the volume of the monolith is formed by hollow spaces.

Abstract: The invention relates to a process for the preparation of glyoxylic hemiacetal esters, in which first glycolic esters are oxydehydrogenated to give glyoxylic esters, and then the latter are reacted with an alcohol. The gaseous reaction mixture formed in the oxydehydrogenation is introduced, together with an excess of an alcohol which is suitable as an entraining agent, into a distillation column and then the water of reaction is distilled overhead together with other low-boilers and part of the excess alcohol, the glyoxylic hemiacetal ester and the remainder of the excess alcohol resulting as the bottom product. In a variant of the process, use is made of an additional inert entraining agent whose azeotrope with water boils below 90 DEG C. and below the alcohol which is used, and then the water of reaction is distilled overhead with the assistance of this entraining agent.

Abstract: A method for making a mixture containing acetic acid, acetaldehyde, and ethanol as the pricipal products, which process comprises reacting carbon monoxide and hydrogen at an elevated temperature and at an elevated pressure in the presence of a supported catalyst prepared by impregnating a carrier with a salt or complex of rhodium and, as a promotor, with at least one non-oxidic compound of an element having an atomic number of 21, 39, or 58 to 71.
