Description
в качестве инсектицида, иревосход щего но де11сти11ю ДДТ и другие ирепараты, нашел применение (-иитрофенилдиэтилтиофосфат. Однако испытани этого вещества покаоали. что в некоторых услови х опо вл етс онасным не только дл насекомых, но и дл pacTOHuii.as an insecticide, and DDT and other drugs, which have been found to be toxic but have found use (iitrophenyl diethyl phosphate. However, tests of this substance have shown that under certain conditions it is dangerous not only for insects, but also for pacTOHuii.
Онпсываемып способ дает возможность нолучить новый инсектицид бис-(4-нитрофенпл)-этилтиофосфат, вл ющи11с неопасным дл растеHHU и обладаюн1,ни, но сравиению с известным, более высокими иисектадидиыми свойствами.This method provides an opportunity to obtain a new insecticide, bis- (4-nitrophenpl) -ethylthiophosphate, which is not dangerous for plants and has, but compared to the known, higher isectadidium properties.
Особенность описываемого способа заключаетс в том. что на наранитрофенол т щелочного или п елочно-земельного металла в среде нри температуре 40-100 де1 ствуют отилдихлортиофосфатом. Взаимодействне иаранитрофенол га с этилдихлорфосфатом провод т в водной среде при темнературе 40-100°.A feature of the described method is. that alkaline or alkaline-earth metal nitrate in a medium at a temperature of 40–10000 is responsible for its di-chlorothiophosphate. The interaction of iaranitrophenol with ethyl dichlorophosphate is carried out in an aqueous medium at a temperature of 40-100 °.
П р Н м е р. К раствору 16,4 г наранитрофенол та натрии в 50 Л1Л воды ностененно нрибавл ют 10 г этилдихлортиофосфата. Реакцию ведут прн хорошем перемешиванин и при темнературе 50-100°. После прибавлени всего этилдихлортиофосфата неремешивание нродолжают 5) течение нескольких часов в зависимости от температуры реакп.и11 (хфи 95° неремеишванне продолжаетс 1,5-2.5 час). После охлаждени выдел етс коричневое маслообразное вещество, которое быстро закристаллизовыпаетс . Кристаллы отдел ют от раствора, норекристаллизоБывают 113 спирта и нолуча.ют бттс-(4-питрофенил)-птилтиофосфат в чистом виде. Температура плавлени чистого вен;ества 12R-127. Дл применени в качестие инсектицида можно использовать неочн ценпое вещество. Выход технического продукта составл ет 77-78%. чистого - более 60%.PREMIER To a solution of 16.4 g of naranitrophenol sodium in 50 ml of water, 10 g of ethyl dichlorothiophosphate were wall-mounted. The reaction is carried out with a good mixing and temperature of 50-100 °. After the addition of all ethyl dichlorophosphate, the unmixing is continued for 5) for several hours, depending on the reaction temperature and 11 (about 95 ° and 1.5-2.5 hours lasts). After cooling, a brown oily substance is released, which quickly crystallizes. The crystals are separated from the solution, but 113 alcohols are recrystallized and no pure btts- (4-pitrophenyl) -tilthiophosphate is obtained. Pure vein melting point; 12R-127. For use as an insecticide, you can use the wrong substance. The yield of technical product is 77-78%. pure - more than 60%.
