The synthesizer is simple and easy to implement, the process for preparing an imidazole ion liquid is simple, the processing temperature is low, the condition is gentle, the substances in a system is utilized in a circulating manner, the raw material utilization ratio is improved, and the rapid and efficient synthesis of the ion liquid is realized.

Description

technical field [0001] The invention relates to the synthesis and application of an ionic liquid for treating biomass, in particular to a synthesis device and application of an imidazole ionic liquid. Background technique: [0002] With the progress of society and the improvement of people's living standards, the people's requirements for the environment are getting higher and higher. Due to the large-scale greening, a large amount of biomass such as branches, leaves, and grass are produced during the maintenance process; at the same time, a large amount of straw-like agricultural waste is produced during agricultural production. At present, most of these lignocellulosic biomass are treated by roadside incineration. On the one hand, it causes serious air pollution. Especially in winter, random burning of lignocellulosic biomass is the main factor causing smog; Smoke seriously affects traffic safety; in addition, burning straw can easily cause fires, which seriously threaten...
