The solubility of H in electrolytes, H reaction consumption and the conductivity of electrolytes under different pressures in an electrochemical hydrogenation reactor were studied. It was found that with an increase in H pressure, H was electrolyzed at the anode, accompanied by the generation of H. The solubility of H in the electrolytes and the conductivity of the electrolytes also increased. At first, the reaction consumption increased, followed by a tendency to be stable at 3 MPa. Therefore, the electrochemical hydrogenation of soybean oil was carried out at a H pressure of 3 MPa. When the current was 120 mA, the temperature was 50°C, the agitation speed was 300 rpm, and the time was 7.5 h, the IV of hydrogenated soybean oil was 99.6 g I/100 g oil, and the TFA content of the oil was 4.3%.
研究了电化学氢化反应器中不同压力下氢在电解质中的溶解度、氢反应消耗量以及电解质的电导率。结果发现,随着氢压力的增加,氢在阳极被电解,同时伴随着氢的生成。氢在电解质中的溶解度以及电解质的电导率也增加。起初,反应消耗量增加,随后在3MPa时有趋于稳定的趋势。因此,大豆油的电化学氢化在3MPa的氢压力下进行。当电流为120mA、温度为50℃、搅拌速度为300rpm且时间为7.5h时,氢化大豆油的碘值为99.6g I/100g油,油中的反式脂肪酸含量为4.3%。
