Patent GB-364046-A (GB)
Title: Manufacture of products for combatting diseases of plants, grain or soils
Filed: 1930-08-18
Abstract: Fungicidal, insecticidal, &c. preparations are obtained by mixing a water-soluble dyestuff with a substituted amide of a fatty acid. Inert powders and other fungicides, such as copper or arsenic compounds and alkaloids, may also be added.  The p  dyestuffs may be water-soluble derivatives of thiazine, oxazine, azines, indoanilines, thiazoles, quinoline, acridine, xanthene, di- or tri-phenyl methane or azo bodies; particular dyes mentioned being dimethyl-amino-naphtho-phenazoxonium chloride, tetramethyl-diamino-diphenyl-methane ketoniminehydrochloride, a salt of hydroxy-tetraiodo-dichloro-o-carboxy phenyl-fluorone,hexamethyl-triamino-triphenyl - methane - hydrochloride, diamino - azobenzene, tetramethyl - diamino - diphenyl - ketonimine, and tetrabrom-fluorescein.  The amides, which are preferably used in the form of their salts with hydrochloric, oxalic, tartaric, benzoic, or salicylic acids, may be the acylated diamines described in Specification 219,304, [Class 2 (iii), Dyes &c.], or the ammonium derivatives thereof described in Specification 294-582, [Class 2 (iii), Dyes &c.], specific examples being dimethyl(or diethyl-) oleyl-amino-ethylamine, stearyl- (or oleyl-) amido-ethylamine, diethyl-linoleyl-amido-ethylamine, dimethyl- (or methyl-ethyl-) stearyl-amido - ethylamine, palmityl-amido-propylamine, and the addition product of dimethyl sulphate and diethyl-oleyl-amido-ethylamine.  According to one example, diamino-azobenzene is dissolved in alcohol or glycol together with an organic or mineral acid, an amide is then added, and the product diluted with water.  Other examples are given.ALSO:Preparations for use as fungicides, insecticides, &c. for the treatment of plants and for sterilizing seeds or infected soil, are obtained by mixing a water-soluble dyestuff with a substituted amide of a fatty acid.  The mixtures may be applied in aqueous solution, or as dry powders mixed with inert substances such as chalk, mica, dolomite, or kieselguhr.  Other fungicides or insecticides such as copper compounds, insoluble arsenic compounds, and alkaloids may be added.  The dyestuffs may, for example, be water-soluble derivatives of thiazine, oxazine, azines, indoanilines, thiazoles, quinoline, acridine, xanthene, di-or tri-phenyl methane, or azo bodies; particular dyes mentioned being: dimethylamino-naphtho-phenazoxonium chloride, tetra-methyl-diamino-diphenyl-methane-ketonimine-hydrochloride, a salt of hydroxy-tetraiododichloro-o-carboxy-phenyl-fluorone, hexamethyltriamino-triphenyl-methane-hydrochloride, p diamino-azobenzene, tetramethyl-diamino-diphenylketonimine, and tetrabrom-fluorescein.  The amides, which are preferably used in the form of their salts with hydrochloric, benzoic, salicylic, oxalic or tartaric acids, may be the acylated diamines described in Specification 219,304, [Class 2 (iii), Dyes &c.], or the ammonium derivatives thereof described in Specification 294,582, [Class 2 (iii), Dyes &c.], specific examples being: dimethyl-oleylamido-ethylamine, stearyl-amido-ethylamine, diethyl-linoleyl-amido-ethylamine, dimethyl-stearylamido-ethylamine, palmityl-amido-propylamine, oleyl-amido-ethylamine, the addition product of dimethyl sulphate and diethyl-oleyl-amido-ethylamine, diethyl-oleyl-amido-ethylamine, and methylethyl-stearyl-amino-ethylamine.  According to one example, diamino-azobenzene is dissolved in an organic solvent, such as alcohol or glycol, together with an organic or mineral acid, an amide is then added, and the product diluted with water.  Other examples are given.
