Alcoholysis of propylene oxide (PO) is achieved over azolate ionic liquids (IL,e.g., 1-hydroxyethyl-3-methyl imidazolium imidazolate) at room temperature, accessing glycol ethers in high yields with excellent selectivity (e.g., >99%). Mechanism investigation indicates that cooperation of hydrogen-bonding of the anion with methanol and that of the cation with PO catalyses the reaction.

The invention relates to the technical field of chemical engineering catalysis and provides application of ionic liquid in synthesis of propylene glycol ether and a synthetic method of propylene glycol ether. The ionic liquid is methyl carbonate ionic liquid and is taken as a catalyst for catalyzed synthesis of propylene glycol ether. The synthetic method of propylene glycol ether comprises the steps of adding epoxy propane and alcohol into a reactor to be in contact with the catalyst, and heating to 50-200 DEG C in a closed environment, so as to obtain propylene glycol ether, wherein the catalyst is the methyl carbonate ionic liquid. The synthetic method of propylene glycol ether is an environment-friendly synthetic process, has no special requirements on production equipment and is beneficial to industrial production and application, and the process is simple and easy to control.

Crystalline Mo-V-O oxides have been used as a catalyst for the hydrolysis and alcoholysis of propylene oxide to diols and ethers, respectively. Relationships between the active crystal facet, the acidity of Mo-V-O catalysts and the activity have been established. Our results indicate that the a-b plane is the active facet for the hydrolysis reaction.
