The invention relates to a new derived arylsulfonyl-triethynylbenzene formula I

which can find application in agriculture as a herbicide for weed control in cereal crops and flax, as well as herbicide composition based on it.

Known acid component of the claimed salt - 2-methoxycarbonyl-N-{ [(4-methoxy-6-methyl)-1,3,5-triazine-2-yl] - aminocarbonyl}-benzosulfimide (compound II), which is used as a herbicide against monocotyledonous weed crops (U.S. Pat. USA N 4959095, CL 71-91) in the form of granules, suspensions, and oil emulsions. However, this component has a low solubility in both water and organic solvents of the type nizkozatratnyh glycols, which are used as fillers in the formulation. Alkali metal salts of the specified acid components are poorly soluble in water (5 g/l) insoluble in organic solvents and less stable to hydrolysis at 20 and 50aboutC.

The proposed connection I infinitely soluble in water and organic solvents, miscible with water, it can be used in the form of water and water-glycol solutions by methods of low-volume and ultra-low volume spraying and, therefore, the minimum to spend the drug, which in turn, reduces the harmful effects on the environment. The ability to use as fillers of various glycols can increase the stability of the formulation, to reduce the temperature of its freezing and enhance penetration of the active substance in plants.

The proposed salt of the formula I can be obtained by the interaction of N,N-Diethylaminoethanol 2-methoxycarbonyl-N-{[(4-methoxy-6-methyl)-1,3,5-triazine-soluble forms of sulfonylurea drugs are known 5% solution of sodium salt of 2-chloro-N-[(4-methoxy-6-methyl-1,3,5-triazine-2-yl)aminocarbonyl] - benzosulfimide (chlorsulfuron) (5% chlorsulfuron, 95% water; Pat. USA N 4127405, CL 71-93, 1978). The drug is not sufficiently stable.

Known stable aqueous suspension based chlorsulfuron (Heb. application N 124295, class a 01 N 47/36, 1984). As stabilizing additives were used salts of carboxylic and inorganic acids: diammonium phosphate, ammonium acetate, lithium, sodium or potassium thiocyanate sodium. The preparation also includes wetting and dispersing additives, thickeners, content of active substance to 34%.

However, the suspension is inferior to the true solutions when spraying precipitation, clogging of the nozzle of the sprayer, the result is uneven processing plants. Additionally, the drug with many components to it and roads, decomposes within 2-3 weeks at 45aboutWith 0.4-0.47 percent.

Known the above acid component (compound II) and its alkali metal salts are used in the form of granules, suspensions and are not applied in an aqueous solution in view of the insufficient solubility in water.
