Problems solved by technology

However, microwave reactors are relatively easy to operate and use on a laboratory scale. When scaling up on an industrial scale, both the process itself and the microwave equipment are very difficult, and the cost is high. The technical difficulty of achieving industrial-scale production is long and economical. Little significance, many unforeseen factors

Embodiment 1

[0030] figure 1 It is the synthesis process equipment flowchart of ionic liquid of the present invention, ①② is respectively the raw material tank of two kinds of reaction materials, ③ is solvent tank. P1, P2, and P3 are three plunger pumps, which transport the reaction materials and solvents in ①②③ to ④. ④ is a jet mixing unit, where the raw materials and solvents in ①②③ are fully mixed. The condenser ⑤ is used to control the mixing temperature at the jet mixer ④. ⑥ is the reaction unit, the reactants mixed at ④ enter ⑥ for reaction, and the heater ⑦ controls the reaction temperature of the reaction unit ⑥. ⑧ is the first separation device, and the upper part of the separated substance is the substance in the solvent tank ③, so it is transported back to the solvent tank ③. Substances in the lower part are fed into ⑨. ⑨ is the second-step separation device. The upper part of the separated substance is the substance in the solvent tank ③, so it is transported back to the so...

Abstract

The invention discloses a technology for synthesizing ionic liquid, which is characterized by comprising the following steps: 1) feeding control; 2) hybrid reaction; and 3) separating treatment. The whole technical process of the technology provided by the invention is a closed circulating system; no by-product is generated; consumption of circulating water is little; no waste water, waste liquid or exhaust gas is emitted; the process is continuously and stably carried out; the full-automatic control on the whole process can be realized; the technical condition is accurately and precisely controlled; the industrial scale amplification for the whole technical equipment can be realized; the technology has operability at technical and economical aspects; and compared with the ionic liquid synthesized according to other conventional technologies, the ionic liquid synthesized according to the new technology provided by the invention has the advantages of high purity, low contents of water and organic impurities and excellent consistency of product quality.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering, and in particular relates to a synthesis process of a series of ionic liquids. Background technique [0002] Ionic liquids are salts composed of organic cations and inorganic or organic anions, which are in a liquid state below 100 °C. Its advantages are that its vapor pressure is almost zero, non-volatile, odorless, non-flammable and non-explosive, easy to separate from the product after use, and can be recycled and reused. It is an ideal substitute for traditional volatile solvents and effectively avoids the use of traditional organic solvents. It is a veritable and environmentally friendly green solvent for serious environmental, health, safety and equipment corrosion problems. It is more and more widely recognized and accepted by people, which is suitable for the requirements of clean technology and sustainable development advocated currently. [0003] Ionic liquids are designa...
