摘要:
Disclosed herein are mixed oxide catalysts for the catalytic gas phase oxidation of alkanes, or mixtures of alkanes and olefins, for the production of aldehydes and carboxylic acids with air or oxygen in the presence of inert gases at elevated temperatures and pressure, and a method for the production of catalysts.
摘要:
The invention relates to mixed oxide catalysts for the catalytic gas-phase oxidation of olefins and methylated aromatics, processes for producing the catalysts and the reaction with air or oxygen in the presence of inert gases in various ratios at elevated temperatures and pressure to form aldehydes and carboxylic acids.
摘要:
The invention relates to mixed oxide catalysts made of hollow shapes for the catalytic gas phase oxidation of olefins, and to a method for producing the catalysts by applying them as a layer to a carrier made of organic material and removing said organic material. The reaction into aldehydes and carboxylic acids occurs by air or oxygen in the presence of inert gases in different quantity ratios, at elevated temperatures and pressure in the presence of said catalysts.
摘要:
The invention relates to a method for filling apparatuses for chemical production with solids using a controllable metering device, and an apparatus, displaceable from place to place, for carrying out the method. The apparatus is suitable in particular for filling heat exchangers, absorption columns, distillation columns or tube-bundle reactors with solids.
摘要:
A single-stage process is described for the preparation of primary aliphatic polyamines of the formula in which R1 and R2 independently of one another are hydrogen, methyl, ethyl or aminomethyl, by reaction of polyalcohols on a Co/Ni catalyst with supercritical ammonia in the presence of hydrogen.
