The author researched and practiced molecule distillation technology for over 10 years. He chose special material to compile a book, specially introducing special examples in the course of developing products and emphasizing practicability of the book. The author put forward the aspects of research application of molecule distillation technology, making the book advanced.  

　　The book is helpful for the production workers who are engaging in chemical products, food and medicine, and engineers who are working in the research and development of molecule distillation technology, which has refereeing value. 

　　The 21st century is an information time, a century of life and S&T, a time of new material and advanced technology developing rapidly and using widely. The 21st century is a time of using new energy high efficiently, cleanly and safely. The 21st century is a century of human developing towards space, ocean and inside earth. The 21st century is a time of natural science happening reform and achieving great progress. The development and rush of science and technology certainly cause new industry revolution. For China-- a developing country, it not only a challenge, but also a chance. Whether we can catch up with the developing opportunity, it is depending on improving the nation's culture level and building a high quality team, who is qualified with the ability of creativity of knowledge and technology. Therefore, we should face the first important strategy: developing education and popularizing knowledge, developing science spirit and advocating scientific methods. In August 1988, when he inspected China science academy Dalian chemical and physical research institute, the chairman- Jiang Zemen emphasized the importance of the work of popularizing science: "when strengthening the progress of science and technology, we should intensify the social work of popularizing science so as to improve the nation's quality. If doing the work well, we can offer the mass base for developing science and technology and creativity."

　　In order to popularize and spread new high-tech, chemical industry press organized several academicians and experts to compile 《new and high-tech science popularization series》. The characteristics of the book are as followings: introducing some high-tech principles, characteristics, important status, the situation and developing prospect of application and industry; Emphasizing "new". It is proved that the introduced new technology and methods are mature and deep, which is application practical technology; Seeking for the unity of picture, knowledge, science, earthliness, readability and interest, so that it represents the important functions of scientific idea and spirit towards creativity.  

　　《new and high-tech science popularization series》 refers to high-tech relating our country's economics and developing. Nine parts of in the first batch concludes: green chemical, gene project technology, nami technology, generating electricity with high efficient environment, newest separation technology (such as supercritical extraction, adsorption separation technology, film technology), chemical laser, biological pesticide. The book will organize to press various new high-tech volumes. We believe that the series are helpful for propagandizing scientific knowledge, scientific methods and spirit, correctly mastering science and improving the nation's quality.
