Abstract

The invention relates to ethanol, acetaldehyde, acetic acid, nitro ethane and N, N-diethyl-hydroxylamine analytical method. It's an organic analysis technology. This analysis technology uses gas chromatography by high separation efficiency and high sensitivity FFAR capillary and flame ionization, rapid qualitative and quantitative analysis of ethanol, acetaldehyde, acetic acid, nitro ethane and N, N-Diethyl-hydroxylamine. The invention has short analysis time, fast, simple, convenient and high-precision, can analysis coexist ethanol, acetaldehyde, acetic acid, nitro ethane and N, N-Diethyl-hydroxylamine quickly.

Description

Technical field [0001] The invention relates to an analysis method when ethanol, acetaldehyde, acetic acid, nitroethane and N,N-diethylhydroxylamine coexist, and belongs to the technical field of organic chemistry analysis. Background technique [0002] With the development of nuclear power, the reprocessing of nuclear fuel has attracted widespread attention. N,N-Diethylhydroxylamine is a new salt-free reducing agent that is expected to be used in nuclear fuel reprocessing. However, the reprocessing of spent fuel is carried out in a strong radiation environment. Under this condition, N,N-diethylhydroxylamine will undergo radiolysis, and the organic matter produced by radiolysis may include ethanol, acetaldehyde, acetic acid, and acetic acid. Nitroethane, these organic substances may affect the separation of nuclear fuel. Therefore, the composition and content of organic substances in the solution must be analyzed to provide an important reference for the application of N,N-diethy...
