The main content of this paper as follows: The acidic strength, reaction temperature, reaction time of Chlorine-aluminate Ionic Liquids with different structure of cation on the activity of transalkylation of MN with TeMB and the selectivity of 2,6-DMN were studied. The optimum reaction condition was obtained: the molar fraction of AlCl_3 is 0.71, molar ratio of 2-MN and TeMB is 1, the amount of ionic liquid is 32wt%, reaction temperature is 20℃and reaction time is 8h using X-xAlCl_3 and X-xAlCl_3 as catalysts; the optimum reaction time is shortened 6h using Et_3NHCl-xAlCl_3 as catalyst.

The Fourth Medicine came into being with the health revolution, the fourth great revolution. In the development history of human beings, each scientific and technical revolution has greatly influenced people's life: the Agricultural Revolution has put an end to the dog-eat-dog age and solved the problem of food and clothing; the Industrial Revolution has greatly improved the efficiency, making people enjoy a comfortable life while work for a shorter time and the Information Revolution has shortened the time and space, providing more leisure time for people. At present, people are faced with the health revolution, aiming to make people have a pleasant, healthy, longevous and high-quality life. To meet that end, the fourth medical workers need to make great efforts. The Fourth Medicine contains scraping and cupping therapy, stone needle therapy, massotherapy, foot massage, body beauty, psychology, physiotherapy, reasonable movement and food therapy, etc.

第四医学的形成是在人类的第四次大革命健康革命启发下而诞生的在人类历史的发展中，每次科学技术革命，无不给人类的社会生活带来巨大影响，农业革命使人们不必自相残杀，弱肉强食，人人可以温饱地生活；工业革命使劳动效率大大提高，使人们在短时间的劳作就可以安逸舒适的生活；信息革命又使时空缩短，大大提高了劳动生产率，使人们的休闲时间大大超过了劳作时间当前所面临的是人类的第四次大革命健康革命它的目标使人们愉快健康长寿，高质量地渡过幸福的一生要想达到这一目标就需要第四医学工作者来完成第四医学包含了刮痧拔罐疗法砭石疗法按摩疗法足疗美容心理学理疗合理运动食疗等
