Abstract

The invention relates to a quick and repeatable method for detecting trace amounts of hydrazine hydrate, which belongs to the technical field of inorganic detection. The invention provides a method for detecting a trace amount of hydrazine hydrate. The specific method is: adding the substance to be tested into a mixed detection solution of a solvent and elemental sulfur and stirring evenly. If the mixed detection solution can display blue color, it indicates that the substance to be tested contains Hydrazine hydrate; Wherein, the solvent is N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone or dimethyl sulfoxide, and the mass fraction of elemental sulfur in the mixed detection solution is 0.0001% to 1%. The method for detecting trace amounts of hydrazine hydrate of the present invention can realize the trace detection of hydrazine hydrate repeatedly and rapidly.

Description

technical field

[0001] The invention relates to a quick and repeatable method for detecting trace amounts of hydrazine hydrate, which belongs to the technical field of inorganic detection. Background technique

[0002] Hydrazine hydrate is a commonly used industrial raw material, and its application is extremely wide. As an important fine chemical raw material, hydrazine hydrate is mainly used for the synthesis of foaming agents; it is also used for cleaning treatment of deoxidation and decarbonation of boilers and reactors In the pharmaceutical industry, it is used to produce anti-tuberculosis and anti-diabetic drugs; in the pesticide industry, it is used to produce herbicides, plant growth regulators, fungicides, insecticides, and rodenticides; in addition, it can also be used to produce rocket fuel, Diazo fuel, rubber additives, etc. The application fields of hydrazine hydrate are still expanding.

[0003] Although hydrazine hydrate has many application fields, hydrazin...
