| 鹽效萃取是指鹽加入到恒沸有機(jī)物水溶液中時(shí),由于鹽與溶劑分子的相互作用,引起溶液液-液相平衡的變化,即溶劑間分配系數(shù)的變化,從而達(dá)到分離的目的。對于環(huán)己酮-水體系而言,由于碳酸鉀與水的相互作用遠(yuǎn)遠(yuǎn)大于環(huán)己酮與水的相互作用,因此,當(dāng)碳酸鉀加入到環(huán)己酮水溶液中時(shí),由于碳酸鉀的鹽析效應(yīng),使環(huán)己酮-水-碳酸鉀體系達(dá)到相平衡狀態(tài)時(shí)所形成的有機(jī)相中含有少量水和極少量碳酸鉀,鹽水相中含有極少量的環(huán)己酮,從而實(shí)現(xiàn)環(huán)己酮-水恒沸物的低能耗分離。 |

鹽效萃取是指鹽加入到恒沸有機(jī)物水溶液中時(shí),由于鹽與溶劑分子的相互作用,引起溶液液-液相平衡的變化,即溶劑間分配系數(shù)的變化,從而達(dá)到分離的目的。 Salt effecting extraction refers to adding salt into the organic aqueous constant-boiling solution, and with the salt-solvent interactions the Liquid-Liquid Equilibria (LLE) in the solution will be changed, which means a variation of the distribution coefficient between solvents and lead to the separation. 對于環(huán)己酮-水體系而言,由于碳酸鉀與水的相互作用遠(yuǎn)遠(yuǎn)大于環(huán)己酮與水的相互作用,因此,當(dāng)碳酸鉀加入到環(huán)己酮水溶液中時(shí),由于碳酸鉀的鹽析效應(yīng),使環(huán)己酮-水-碳酸鉀體系達(dá)到相平衡狀態(tài)時(shí)所形成的有機(jī)相中含有少量水和極少量碳酸鉀,鹽水相中含有極少量的環(huán)己酮,從而實(shí)現(xiàn)環(huán)己酮-水恒沸物的低能耗分離。 When potassium carbonate is added into the cyclohexanone-water system, a cyclohexanone-water- potassium carbonate system can be found in the solution. Because the potassium carbonate-water interaction far surpasses the cyclohexanone-water interaction, when the cyclohexanone-water- potassium carbonate system reaches a state of equilibrium, there will be little water and trace amount of potassium carbonate left in the organic phase and trace amount of cyclohexanone in the salt-water phase, which provides an energy-saving separation technology for the cyclohexanone-water azeotrope. 句子太長了,搞的可能不是太通順。 |
