Diols of 3 to 10 carbon atoms are catalytically dehydrogenated over a catalyst containing copper and chromium in a first stage in which the diols are passed in the liquid phase over the catalyst, and subsequently the reaction product obtained is passed in the gas phase over the catalyst.

Process for the catalytic dehydrogenation of diols

A process and apparatus for the continuous production of alkylesters of saturated aliphatic carboxylic acids by reacting olefins with carbon monoxide and alkanol in the presence of a catalyst consisting of a cobalt compound and a promoter selected from the group consisting of pyridine, non-ortho-substituted alkylpyridines and mixtures at elevated pressure and elevated temperature, the reaction based on olefins having at least 8 C atoms and being carried out in a reactor wherein the flow characteristic is adjusted so that tubular flow without back-mixing predominates, and wherein the raw materials are supplied in the desired ratios at the input side of the reactor.
