Paragraph 0115; 0117; 0119, (2017/03/08)
The invention discloses benzothiazole ionic liquid and a preparation method as well as application thereof. The preparation method of the benzothiazole ionic liquid comprises the steps of reacting benzothiazole and acid containing target anions, with equal molar weight, under a low temperature condition, and preparing corresponding benzothiazole salt ionic liquid, wherein the acid containing the target anions is one of sulfuric acid, phosphoric acid, perchloric acid and nitric acid. The benzothiazole ionic liquid can serve as a mild, special and efficient catalyst of a specific organic synthesis reaction, and is convenient to recover and reuse circularly and capable of effectively alleviating corrosion to equipment, and the production cost is lowered. In a ricinoleic acid dihydric alcohol ether ester preparation process, by adopting the benzothiazole salt ionic liquid as the catalyst, the catalytic efficiency is high, the catalyst and a product are easy to separate, the synthetic product is high in purity, the posttreatment is simple, the generation of a great amount of wastewater due to catalyst treatment is avoided, and the environmental pollution is reduced.
