Amplification experiment of ethylhexylglycerin

In a 20 L jacketed glass kettle equipped with a mechanical stirrer, thermometer, dropping funnel and condenser, add 4 kg of 2-ethylhexyl glycidyl ether, and control the temperature at 10 to 20 °C with stirring. Kg acetone and catalyst 0. 1 kg, the addition time is 40 min, and the incubation reaction is 2 h. The remaining acetone was distilled off under reduced pressure, and formic acid was added. 8 kg, distilled water 8 kg, reacted at 50 ~ 55 °C for 3 h, and allowed to stand for liquid separation. The oil phase was neutralized with sodium hydrogencarbonate, washed with water for 2 times, subjected to short-path distillation, and the degree of vacuum was 40 to 50 Pa, and a fraction of 135 to 145 ° C was charged. By gas chromatography analysis, purity 99. 3%, yield 89. 1%, colorless and tasteless.
