In this study, the possibility of the formation of lower olefins from dimethyl ether and methanol on catalysts containing Mg-Zn-Zr-B-HSZ and Mg-Zn-Zr-P-HSZ was studied, and the process was evaluated quantum chemically. According to the results obtained by IR-Fur spectroscopy, during the catalytic conversion of DME (dimethyl ether) on the surface of catalysts containing Mg-Zn-Zr-B-HSZ and Mg-Zn-Zr-P-HSZ ketenes at temperatures below 180 °C and oxonium intermediates at 320 °C (intermediate). compounds) are confirmed by experimental spectra and theoretical quantum-chemical calculations. It was shown that the formation of olefins below DME occurs by the carbene mechanism at low temperatures and by the oxonylide mechanism at high temperatures.
