Uses and synthesis of Cupferron powder

Cupferron powder is an important analytical reagent, it is the ammonium salt of N-nitrosohydroxylamine, commonly known as Cupferron.Cupferron CAS 135-20-6 Usually it is a white or yellowish bright scaly crystal, with sweet smell, the colour will be darkened due to the decomposition of it for a long period of time, however, Cupferron Raw Materials can be used in the analysis... However, Cupferron Raw Materials can also be used in analytical applications.

Applications / Functions of Cupferron powder

• Reagent for chemical analysis, determination of aluminium, copper, iron, titanium, zirconium and other metals.
• Polymerisation inhibitor, Cupferron powder can be used as an alternative to the phenol inhibitor BHT, which is currently used in large quantities, due to Cupferron's unique polymerisation inhibition properties and the small amount of Cupferron powder used.

Physicochemical Property of Cupferron powder

White or milk-coloured flaky crystals. Melting point 163-164°C, easily soluble in water and alcohol.

Production methodprocess of Cupferron powder

Cool the phenyl hydroxylamine ethyl ether solution in ice solution, pass ammonia to excess, add n-butyl nitrite dropwise with stirring and continue to pass ammonia, add it all in about 1h, then stir for 15min, filter out the copper and iron precipitate, wash with ether, dry to get Cupferron CAS 135-20-6
