FIELD: chemistry.SUBSTANCE: present invention relates to a method of producing a plant stimulator for increasing germination capacity of seeds. The disclosed method involves reaction of 2,2-dichloro-cyclopropylmethanol with dimethyl phosphite at temperature of 40-50°C in the presence of tetraethylammonium iodide, sodium hydroxide, carbon tetrachloride, stirring the mixture at room temperature for 4-5 hours, adding carbon tetrachloride until precipitation, separation thereof, washing with hydrochloric acid solution and water, separating the organic layer, extracting the aqueous layer with carbon tetrachloride, drying the organic layer for 1-2 days, distilling the solvent, vacuum distillation of the residue and dissolving the obtained dimethyl-2,2-dichloro-cyclopropylmethylphosphate in water until 0.01% aqueous solution is obtained.EFFECT: novel method which enables to obtain a stimulator which increases germination power and capacity of seeds and accelerates the beginning of ripening of cereal crops.1 cl, 1 ex |
