Abstract

The present invention belongs to the field of ionic liquid preparing reactor, and is especially one multifunctional ionic liquid preparing reactor. The reactor is one kettle type or one horizontal reactor, which has a sandwiched reactor body with medium inlet and outlet, gaseous material inlet pipe, liquid material inlet pipe, vacuum pipe, vacuum suction filtering pipe, slurry stirring motor, temperature sensor, pressure sensor, sight glass, condensate return pipe, solid material outlet, bottom sampling port, etc. The present invention makes it possible to complete multiphase reaction or homogeneous reaction and subsequent product separation and purification, and has high reaction conversion rate, high equipment utilizing rate, less material conveying links and less impurity introduction.

Description

technical field [0001] The invention belongs to the field of reactors for preparing ionic liquids, in particular to a multifunctional reactor for synthesizing and preparing ionic liquids. Background technique [0002] Room Temperature Ionic Liquids (RTILs) are salts composed of organic cations and inorganic or organic anions that are liquid at or near room temperature, referred to as ionic liquids. Because of its excellent characteristics such as low melting point (always in a liquid state at room temperature), low vapor pressure, and low volatility, it has very good industrial application prospects, and its application fields are becoming more and more extensive, involving organic synthesis, extraction and separation, electrochemistry, biological Catalytic processes etc. [0003] At present, most of the ionic liquids are synthesized and purified on a small scale in the laboratory, the raw materials are expensive, the operation is complicated, the cost of raw materials is h...
