FIELD: metallurgy.SUBSTANCE: invention relates to the method of production of cyanamides of pentavalent stibium with common formula ArSbNCNH, where Ar = CH, 4-CH-CH. The method includes interaction of pentasubstitution derivate of stibium ArSbHal, where Ar = CH, 4-CH-CH, Hal = Cl, Br, with carbamide at temperature 180°C in mol ratio 1:10 during mixing for at least 10 minutes, and further 3 times mixture washing initially by water (30 ml), and then by acetone (30 ml). Besides method of ArSbNCNH production and method of production of cyanamides of pentavalent stibium with common formula ArSb(NCNH), where Ar = CH, 4-CH-CHare suggested.EFFECT: invention produces cyanamides of pentavalent stibium that can be used as nitrogen fertiliser, defoliant for cotton-plant, herbicides for corn and other vegetable crops, and for production of melamine, dicyandiamide and other important nitrogen compounds.3 cl, 1 ex |
