FIELD: chemistry.
SUBSTANCE: 3-methyl-4-nitrosopyrazoles 
are obtained via cyclocondensation of hydrazine salts with a nitrosation product obtained from 4,4-dimethoxybutan-2-one held in aqueous hydrochloric acid first. The obtained compounds can be used as modifiers and stabilisers of rubber mixtures, particularly during vulcanisation of butadiene-nitrile rubber and as fungicides.
EFFECT: novel method of producing 3-methyl-4-nitrosopyrazoles and obtaining novel 3-methyl-4-nitrosopyrazoles.
