Abstract: The hydrogenation of esters of benzene-dicarboxylic acids is carried out on supported catalysts containing a Sub-Group VIIII metal on a macroporous support. A process for the hydrogenation of benzene-dicarboxylic acid ester(s) with hydrogen in presence of a supported catalyst containing Sub-Group VIII metal(s) on a macroporous support. If the ester is dimethyl terephthalate, this excludes hydrogenation on a catalyst containing ruthenium, with or without Sub-Group I, VII or VIII metal(s), on a support with an average pore diameter (APD) of at least 50 nm and a BET surface of not more than 30 m /g, with an active metal content of 0.01-30 wt.% and a ratio of (active metal surface):(support surface) of less than 0.05, and/or on a catalyst containing 0.01-30 wt.% active metal(s) as above on a support in which 10-50 vol.% of the pores consist of macropores with a diameter of 50-10,000 nm and 50-90 vol.% consist of mesopores with a diameter of 2-50 nm.

Abstract: A process for continuous industrial production of unsaturated aliphatic aldehydes having a boiling range from 95 to 136.degree.C by oxidative dehydrogenation of the corresponding alcohols with an oxygen-comprising gas over a supported catalyst consisting of copper, silver and/or gold on an inert support in a tube bundle reactor, rapid cooling of the reaction gases and removal of the aldehydes from the resulting condensate with recycling of the unconverted alcohols comprises a) vaporizing the alcohol, b) admixing the alcohol vapor with an oxygen-comprising gas, c) initially passing the resulting oxygen-comprising alcohol vapor at above the dew point of the alcohol but below the commencement temperature of the reaction through a layer of one of the abovementioned supported catalysts which is at least 0.5 cm in thickness and only then d) reacting the oxygen-comprising alcohol vapor at from 300 to 600.degree.C in a sufficient number, for the desired capacity, of parallel reaction tubes surrounded by a fluidic heat transfer medium, packed with the supported catalyst and having an internal diameter D of from about 0.5 to 3 cm and a length of at least 5 cm, to form the corresponding aldehyde.

Abstract: In the reactor for carrying out catalytic organic reactions in the gas phase, having reaction tubes (A) arranged between tube plates (B), the reaction tubes have an internal diameter in the range from 0.5 to 3 cm, the reaction tube length/internal diameter ratio is between 2 and 10, and a fluid heat transfer medium flows in the lateral direction around the reaction tubes (A). The tube bundle reactor is particularly suitable for exothermic organic reactions. … …

Abstract: 3-Formyl-5,6-dihydro-2H-pyran is prepared by conversion of acrolein in the presence of water, acids and halohydrocarbons of 1 to 6 carbon atoms and 1 to 6 halogen atoms as solvents at from 60 to 150.degree.C. The 3-formyl-5,6-dihydro-2H-pyran obtained by the novel process is a valuable starting material for the preparation of dyes and crop protection agents.

Abstract: The invention relates to a method for hydrogenating a benzene polycarboxylic acid or a derivative thereof or of a mixture comprised of two or more thereof with a gas containing hydrogen in the presence of a catalyst. Said catalyst comprises ruthenium as an active metal which is deposited alone or together with at least one metal of subgroups I, VII, or VIII of the periodic table on a support, whereby the support contains macropores. The invention also relates to novel hydrogenated products obtained by hydrogenating benzene polycarboxylic acid (derivatives) and to the use thereof as plasticizers in plastics.
