Description
К числу органических соединений , облах ающих сильными инсектицидными сгюйствами, относитс тетраэтилтиопирофосфат, впервые полученный в чистом виде в 1932 г.Tetraethylthiopirophosphate, first obtained in pure form in 1932, is one of the organic compounds possessing strong insecticidal agents.
Способы получени подобных препаратов в чистом виде сложны и трудоемки.The methods for preparing such preparations in their pure form are complex and time consuming.
Согласно изобретению предлагаетс способ получени нового инсектицида - тстраэтилтионирофосфата . Способ отличаетс простотой и доступностью и заключаетс в том, что на хлорангидрид днэтилфосфорной кислоты действуют диэтилмопотиофосфорным натрием. Полученный продукт имеет химическое строение:According to the invention, a method for producing a new insecticide, tstraethylthionophosphate, is proposed. The method is simple and easy to use, and consists in the fact that dichloric acid chloride is affected by diethyl monopothiophosphoric sodium. The resulting product has a chemical structure:

Продукт обладает сильными инсектицидными свойствами, способству полному уничтожению клеща в концентрации 0,0062% по препарату (0,0031% по действующему началу).The product has strong insecticidal properties, contributing to the complete destruction of the tick at a concentration of 0.0062% for the preparation (0.0031% at the current beginning).
При м ер. К диэтилфосфористо3viy натрию, полученному из 10 гAt meer. To diethylphosphorous 3viy sodium, obtained from 10 g
диэтилфосфористой кислоты и 1,7 г металлического натри в растворе бензина, прибавлено 2,3 г серы. После окоичани реакции к полученной таким образом натриевой соли диэтиллюнофосфорной кислоты медленно прибавл ют 12,5 г хлорангидрида дпэтилфосфорной кислоты. Затем раствор отдел етс or BbmaBHiero в осадок хлористого if;TpHH, остаток обрабатываетс водой до растворени NaCi п водный pacTiBOp взбалтагваетс с небольнн-1М количеством афира. Эфирна выт жка сушитс хлористым кальцием . После 01ГОИКИ растворител остаток перегон етс в вакууме.diethylphosphorous acid and 1.7 g of metallic sodium in a solution of gasoline, added 2.3 g of sulfur. After the reaction has been initiated, 12.5 g of dipethylphosphoric acid chloride are slowly added to the sodium salt of diethyl phosphoric acid thus obtained. The solution is then separated or BbmaBHiero into a precipitate of if; TpHH chloride, the residue is treated with water until NaCi is dissolved and the aqueous pacTiBOp is agitated with a non-1M amount of morsel. The ether extract is dried with calcium chloride. After the solvent solvent, the residue is distilled in vacuo.
Полученный продукт кипит в пределах 142-143 при остаточном дазле1П1Й в 4 мм ртутного столба.The resulting product boils in the range of 142-143 with a residual pressure of 4 mm Hg.
