بخشی از مقاله (انگلیسی)

A thermodynamic analysis of the reactions for the conversion of dimethyl ether into valuable products of the gas and oil industry and of propylene, formaldehyde, and 1,3-butadiene in particular was carried out. The temperature dependence of the equilibrium composition in the reaction for the production of 1,3-butadiene from dimethyl ether was determined. Calculation of the temperature dependence of the equilibrium composition in the reaction of propylene with formaldehyde with the formation of 1,3-dioxane, 1,3-butanediol, and 2-buten-1-ol showed that the main product at equilibrium is 2-buten-1-ol.

Petrochemists have recently paid special attention to the production of valuable chemical products based on dimethyl ether (DME), which is one of the main products of the Fischer-Tropsch synthesis of oxygenates from syngas.

In [1] the mechanism of the reaction for the synthesis of olefns from methanol and DME at zeolite catalysts is considered, and various mechanisms such as isomerization and synchronous mechanisms for the formation of C–C bonds in the transformation of DME as well as the role of catalysts and temperatures in these reactions are discussed. In [2] kinetic aspects of the synthesis of olefns from methanol and DME at zeolite catalysts were examined.

The dependence of the activity of zeolite MFI in the transformations of DME into hydrocarbons on the spectral and textural characteristics and acidity was studied in [3]. Comparative results obtained during the synthesis of C5+ hydrocarbons are presented. It was established that high selectivity in the hydrocarbons of the gasoline fraction is achieved with the use of a catalyst based on a sample of zeolite MFI, for which in the infrared diffuse refection spectra there are bands characteristic of the acid centers of H3 O+ .

It is interesting to note the results of studies [4], which examine the treatment of DME with associated petroleum gas in a mixture of synthetic hydrocarbons. It was established here that it is possible to obtain hydrocarbons direct from DME in a singlestage process. The presence in the vapor–gas mixture of such components as hydrogen, carbon dioxide, and water ensures high stability of the catalytic system. In [5-11] on the basis of data on the state of the intermediates formed from DME on the surface of the heterogeneous catalysts some catalytic reactions with the participation of DME were examined: methylation, ethanol synthesis, partial oxidation with the production of a series of compounds.
