A MANUFACTURING METHOD OF A NITRIC OXIDE

摘要

PURPOSE: A method for manufacturing nitric oxide is provided to secure the safety of manufacturing processes by implementing the manufacturing processes at room temperature. CONSTITUTION: Nitric oxide is generated by mixing sodium nitrite and sulfuric acid(S11). The sodium nitride is stirred with deionized water, and the sulfuric acid is introduced(S12). A primarily refining process eliminates the sulfuric acid, nitrogen dioxide, and carbon dioxide using sodium hydroxide or potassium hydroxide(S2). A secondary refining process eliminates carbon dioxide and moisture using an absorbing agent(S3). The absorbing agent is selected from molecular sive, activated charcoal, silica gel, and activated alumina gel.
