Abstract

Organic derivatives of hydrazine are prepared by contacting an isohydrazone with an acid to yield a reaction medium containing a hydrazine salt and subsequently converting said hydrazine to a hydrazine derivative in the presence of the reaction medium from which aldehyde or ketone may have been separated. In a modification of the process the isohydrazone is contacted with a mixture of the acid and a substance containing an acidic function with which the hydrazine salt reacts to form a hydrazine derivative. Examples describe the preparation of hydrazo-diisobutyronitrile, dehydrourea, maleic hydrazide, benzene sulphonylhydrazide, oxy - bis - (benzene sulphonylhydrazide), thiosemicarboxide, N,N1-di - (b - carboxy - acroyl) - hydrazine (which may be hydrolysed to maleic hydroxide and maleic acid), and N-phthalimido-phthalimide. Reference has been directed by the Comptroller to Specifications 890,334 and 893,388.ALSO:In Example 1, an aqueous solution of hydrazine sulphate is prepared by adding methyl ethyl ketone isohydrazone to aqueous sulphuric acid and distilling off the methyl ethyl ketone formed. Reference has been directed by the Comptroller to Specifications 890,334 and 893,388.
