Description

0,0-диметил-0 -2,4,5-трихлорфенилтиофосфат («тролен) примен етс  как одно из наиболее эффективных средств борьбы с кожным оводом скота.0,0-dimethyl-0 -2,4,5-trichlorophenyl thiophosphate (" trolene) is used as one of the most effective means to combat skin gadfly of livestock.

Известен способ получени  «тролена на основе различных галоидангидридов тиофосфорной кислоты и 2,4,5-трихлорфенола.A known method for producing " trolene based on various thiophosphoric acid halides and 2,4,5-trichlorophenol.

Недостатком известного способа  вл етс  использование труднодоступных галоидангидридов тиофосфорной кислоты.A disadvantage of the known method is the use of hard-to-access thiophosphoric acid halides.

Предлагаетс  способ получени  «тролена путем взаимодействи  диметилового эфира диэтнламида фосфористой кислоты с 2,4,5-трихлорфенолом при нагревании с последующим добавлением к реакционной массе порошкообразной серы лри температуре 110-120°.A method for the production of troline by reacting phosphoric acid diethylamide dimethyl ester with 2,4,5-trichlorophenol with heating and then adding powdered sulfur to the reaction mass of 110-120 ° is proposed.

Предлагаемый способ лишен недостатков известного способа, так как основан на применении более доступных исходных продуктов, и позвол ет расширить их ассортимент.The proposed method does not have the disadvantages of the known method, since it is based on the use of more affordable starting materials, and allows for the expansion of their range.

Прим ер. Смесь 7,5 г (0,05 мол ) диэтиламида диметилового эфира фосфористой кислоты и 9,8 г (0,05 мол ) 2,4,5-трихлорфенола нагревают 3 часа при 100° в токе аргона, затем выдерживают 1 час в вакууме водоструйного насоса при 40-50°. После охлаждени  к реакционной массе прибавл ют 1,6 г порошкообразной серы и нагревают при ПО-120° в токе аргона. После охлаждени  реакционную массу пе регон ют в высоком вакуме (0,005мм). Выход «тролена 11,5 г (72%),Approx. A mixture of 7.5 g (0.05 mol) of phosphorous dimethyl ether diethylamide and 9.8 g (0.05 mol) of 2,4,5-trichlorophenol is heated for 3 hours at 100 ° in a stream of argon, then kept for 1 hour in a vacuum water jet pump at 40-50 °. After cooling, 1.6 g of powdered sulfur are added to the reaction mass and heated at PO-120 ° in a stream of argon. After cooling, the reaction mass is distilled under high vacuum (0.005 mm). The output of "trolley 11.5 g (72%),
