    Abstract: FIELD: organic chemistry, herbicides. SUBSTANCE: invention describes composition designated for application as herbicide and comprising effective amount of chloroacetamide herbicide as herbicide active component and substance reducing precipitation temperature of chloroacetamides that represents at least one compound of the formula: wherein R1 means chlorine atom or methoxy-group; R2 means hydrogen or halogen atom. This composition comprises chloroacetamide herbicide taken in the concentration at least about 40 mole % and substance reducing precipitation temperature is taken in the amount sufficient to provide preparing chloroacetamide-free composition at temperature lower by about 10 C. Invention describes also method for preparing dimetheneamide composition that is stable at low temperature. EFFECT: improved preparing method, valuable properties of composition. 8 cl, 4 tbl, 1 dwg
