For a long time, alkali is the main modification reagent for ramie modification due to its good effect and low cost. However, the large consumption of alkali in the processing leads to a serious pollution to the environment. To develop a new eco-friendly modification method, a mixed green solvent composed of 95 wt% 1-butyl-3-methylimidazolium chloride ionic liquid and 5 wt% water was employed in the...
A basic ionic liquid, namely choline hydroxide, was prepared and supported on MgO to form Choline hydroxide/MgO material. The supported ionic liquid material was characterized by XRD, FT–IR and TG and used as a catalyst in one-pot synthesis of dimethyl carbonate from propylene oxide, methanol and carbon dioxide. A good catalytic performance was obtained with 98% conversion of epoxide and selectivity...
