摘要

The present invention relates to a process for catalytic synthesis of a low-carbon polyether-based compound by using an acidic ionic liquid as the catalyst. The low-carbon polyether-based compound is prepared from an acetal compound and paraformaldehyde under the following conditions: reaction temperature of 70°C-200°C and reaction pressure of 0.2MPa-6MPa. The process is mainly characterized by avoiding the use of concentrated sulfuric acid or trifluoromethanesulfonic acid, which has strong corrosivity and will pollute the environment, as the catalyst. The ionic liquid being used has no corrosivity and will not pollute the environment, and has high selectivity for the low-carbon polyether-based compound product. Outstanding characteristics of the process include: the reaction system is free of water, the product can be very easily separated from the catalyst, the product can be widely applied, the ionic liquid can be used repeatedly, and therefore the outlook of the use of the process on industrial scale is very good.
