Definitions

  • the invention relates to a process for the production of acetic acid by catalytic conversion of carbon dioxide and methane.
  • Acetic acid is one of the important basic organic chemicals and is used extensively in the chemical industry. The largest proportion of industrially used acetic acid is used for the production of polymers. Substantial amounts are also used as solvents immediately or after esterification with alcohols. Furthermore, acetic acid is the starting material or intermediate for many industrially used reactions.
  • acetic acid is the oxidation of aliphatic hydrocarbons, in particular of n-butane in the liquid phase.
  • Air or oxygen-enriched air serves as the oxidizing agent.
  • the implementation takes place at temperatures of 150 to 200 ° C. and
  • ERS ⁇ ZBL ⁇ (RULE 26) Pressures between 3 and 8 MPa. Which pressures and temperatures are used in the individual case is determined in particular by the type of hydrocarbon used. The reaction can be carried out with or without catalysts.
  • the oxidation of acetaldehyde is also a proven way of producing acetic acids.
  • the oxidizing agent is air, to which oxygen can be added.
  • the reaction proceeds via peracetic acid as an intermediate at temperatures from 50 to 100 ° C and pressures from 0.2 to 10 MPa.
  • the object was therefore to provide a process which is as selective as possible and which, starting from inexpensive raw materials, leads to acetic acid.
  • acetic acid consists in the reaction of carbon dioxide and methane at temperatures from 100 to 600 ° C and pressures from 0.1 to 20 MPa in the presence of catalysts which contain one or more metals from groups VIA, VIIA and VIIIA of the Periodic Table of the Elements.
  • Carbon dioxide has hardly been described as a starting material for the production of acetic acid.
  • Known investigations relate to the implementation of carbon dioxide with water
  • ERS ⁇ ZBLA ⁇ (RULE 26) hydrogen in the presence of catalysts. It leads to a complex reaction mixture, which also contains acetic acid.
  • the reaction of carbon dioxide with methane has so far only been carried out under the influence of silent electrical discharges and also results in a mixture of different oxygen-containing organic compounds, including acetic acid. However, such a reaction path is not suitable for technical use.
  • the new process enables acetic acid to be obtained under technical conditions that are common in chemical syntheses.
  • the raw materials are available in large quantities, carbon dioxide as a by-product of technical processes, methane e.g. in the form of natural gas or as a by-product of oil processing in refineries.
  • Carbon dioxide is used in the commercial form with a Ge of at least 99.7%, preferably at least 99.9% CO2. It essentially contains the constituents of the air, namely nitrogen, oxygen and argon. The methane is also used in a purity of at least 99.5%. If appropriate, catalyst poisons, in particular sulfur compounds, have to be removed beforehand by known processes. The starting materials can be reacted in a molar ratio of 1: 1, but the excess of one of the reaction components does not interfere. Molar ratios of 1: 1.1 to 1: 1.5 are preferred

  • Aluminum silicates and zirconium dioxide have also proven successful.
  • Preferred carriers are ⁇ - ⁇ 2 ⁇ 3 and silicon dioxide.
  • the performance of the catalysts is improved in many cases by adding activators.
  • Alkali, alkaline earth and lanthanum compounds in particular the hydroxides and oxides of lithium, sodium, potassium, magnesium and calcium as well as anthane oxide, are used with success.
  • the composition of the catalysts can be varied over a wide range with regard to the type and proportion of the components.
  • Catalysts which, based in each case on the catalyst mass, contain 3 to 20% by weight of catalytically active metals and 80 to 95% by weight of carriers have proven successful.

  • the heterogeneous catalysts used according to the invention are produced by the processes known for this class of substances, in particular by precipitating the components or by impregnating carriers.

  • suitable precipitation reagents such as alkaline compounds, for example the alkali metal carbonates or the hydroxides of the alkali metals and the alkaline earth metals.
  • the carrier substance instead of precipitating the carrier substance together with the other catalyst constituents, it can also be suspended as an insoluble solid in the solution of the metal compounds and the dissolved components precipitated in their presence.

If the metal salt solutions act on the support in several stages, solutions of different concentrations and / or solutions of different compositions can be used in the individual stages, that is to say, for example, for the production of catalysts which contain a plurality of active metals and which apply components to the support one after the other. Additional reaction steps can be provided between the individual impregnation stages, for example the active metals can be individually fixed on the support.
