RODENTICIDE Russian patent published in 2000 - IPC

FIELD: biologically-active compounds and pest control. SUBSTANCE: active component of rodenticide is, taken in effective amounts, indan-1,3-dione derivatives prepared according to multistage flowsheet. For that aim, benzyl cyanide is subjected to interaction with ethylacetate in sodium ethylate medium to form phenylacetone, which is then chlorinated with sulfuryl chloride in benzene to give 1-chloro-1- phenylacetone. The latter interacts with mixture of alkylbenzenes (benzene/toluene/ethylbenzene/isopropylbenzene 1:1.2: 1.4: 1.6). Mixture of thus obtained ketones are condensed with dimethyl phthalate and to resulting product are added products of regeneration of liquid organic waste from the last synthesis stage. Methylcellulose, sodium carboxymethylcellulose, vegetable oil and others can be used as fillers. Rodenticide may also contain attractant, dye, water, and preservative. EFFECT: enhanced biological activity. 6 cl, 4 tbl, 4 ex
