B. MVE is prepared by pyrolysis of dimethyl acetal at high temperature in the presence of a solid catalyst. In general, the pyrolysis of dimethylacetal is carried out in the vapor phase. Dimethylacetal was vaporized and introduced into a fixed-bed reactor filled with calcium phosphate catalyst. In the reactor, dimethylacetal split into MVE and methanol at 320 °C and under atmospheric pressure. The conversion of dimethylacetal was 95%, and the selectivity to MVE was more than 98%.
Yield:-
Reaction Conditions:
with magnesium oxide at 400;Inert atmosphere;Reagent/catalyst;
Steps:
1-6 Magnesium oxide catalyst catalyzes ethylene glycol dimethyl ether to prepare vinyl methyl ether.
In a miniature atmospheric fixed-bed reactor, ethylene glycol dimethyl ether with a space velocity of 1h-1 is introduced, nitrogen is used as a balance gas, and 0.5g of magnesium oxide is used as a catalyst. The reaction was carried out at 400° C., the conversion rate of ethylene glycol dimethyl ether was 22.5%, the molar selectivity of vinyl methyl ether was 84.3%, and the molar selectivity of methanol was 76.9%.
