| abstract | n - Dodecylbenzene - p - sulphonhydrazide is prepared by reacting n-dodecylbenzene with chlorosulphonic acid, and then reacting the product so formed with hydrazine hydrate. The substance is used in biocidal compositions (see Group VI).ALSO:The hydrazine salt of N, N1 hydrazine disulphinic acid is prepared by reacting hydrazine or hydrazine hydrate with sulphur dioxide in the presence of a solvent e.g. absolute alcohol. The product is used in biocidal compositions (see Group VI).ALSO:A liquid biocidal preparation comprises a hydrazine derivative containing a substituted =N-N= radical in which either (a) only one nitrogen atom carries 1 or 2 substituents, of which one or both contain one or more of the groupings <FORM:0726684/VI/1> ; or (b) both nitrogen atoms each carry 1 or 2 substituents such that at least two substituents contain one or more of said groupings and are attached to different nitrogen atoms but do not form part of a ring structure which includes said nitrogen atoms, the aforesaid groupings being attached to nitrogen in each case either directly or through 1 to 4 carbon atoms, a sticker (defined) and an aqueous medium. Examples of (a) are monoacetyl hydrazine, monopalmitoyl hydrazide, monobenzoyl hydrazide, cyclohexane carboxylic acid hydrazide, thiosemicarbazide, n-dodecyl-benzene-p-sulphonhydrazide, thiocarbohydrazide and the cyano-acyl hydrazines, e.g. cyano-acetyl hydrazine. Examples of (b) are N, N1 hydrazine disulphonic acid, N, N1 hydrazino-diacetic acid, N, N1 diacetyl hydrazine and N, N1 diformyl hydrazine. Substituents which do not contain the above groupings are alkyl, aryl or aralkyl, e.g. N, N1 diformyl-N-phenyl hydrazine. Specified also is the product of reaction between sulphur dioxide and hydrazine or hydrazine hydrate (possibly hydrazine salt of N, N1 hydrazine disulphinic acid). Basic hydrazines may be employed in the form of their salts with acids, e.g. hydrochloric, sulphuric, nitric, and various phosphoric acids. Acid hydrazines may be used as salts with sodium, potassium and ammonium. The preparations may be in the form of emulsions or suspensions containing solvents such as mineral oils. Other pesticides, plant nutritives, plant hormones, carriers and diluents may be present. Specified stickers are gelatin, dextrin, agar agar, sodium alginate, gum tragacanth and gum arabic. Specified dispersing agents are alkyl sulphates, alkyl aryl sulphonates, sulphosuccinates and polyethylene oxide derivatives. |
