Yao, Zhiwei published the artcileSynthesis and application of novel sulfonic acid-functionalized ionic liquid with benzothiazole cation, Name: 1,4-Dioxaspiro[4.5]decane, the publication is Gongye Cuihua (2013), 21(5), 54-57, database is CAplus.
A novel sulfonic acid-functionalized ionic liquid [(CH2)3SO3HBth][HSO4] was prepared with benzothiazole as the cation and hydrogen sulfate as the anion, and was used for catalyzing the ketalization of cyclohexanone with glycol. The effects of reaction time, mole ratio of reactants, the dosage of the water carrying agent and the catalyst and the repeated use of the catalyst were investigated. The results showed that 1,4-dioxaspiro[4,5]decane yield of over 97.30% was attained under the optimal reaction condition as follows: cyclohexanone amount 0.01 mol, glycol amount 0.02 mol, catalyst dosage 5% of cyclohexane mol, the amount of water carrying agent cyclohexane 10 mL, and reaction time 3 h. The catalyst possessed good stability, and its activity did not decrease obviously after repeated use for five times.
