      The program “The Preparation of High-Purity NO Gas” we developed by ourselves in June, 2005 became a State Innovation Fund program. This project began in June 2005 and ended in June 2007. It aims to produce NO gas with 99.9%purity, and thus to realize industrialization and improve the product quality and purification technology to international advanced level.
As a new type of functional material, high-purity NO gas can be widely used in many fields of chemical industry, medical and electronics. Its functions mainly reflect in:
1. As an urgent terminator of PVC in production process,the high-purity NO gas has the superiority of reacting rapidly and distributing uniformly. It is easy to control and simple to operate, it also has longer shelf life compared with the liquid type termination agent we used at past. Thus is widely used in the field of PVC production.
2. In recent years, as a medical suction gas of emergency medicine, NO has made a lot of progress in the study of human biological function. It has important physiological functions in cardiovascular system, nervous system, immune system, and so on. Approved by drug supervision departments in United States and European Union's, NO suction therapy become a treatment of respiratory failure.
3. As silicon semiconductor devices in the production of gate oxide of nitrogen agent, high-purity NO can substitute for nitrous oxide as a nitriding agent. It doesn’t need the reaction condition of high pressure and high temperature and is easy to control.
