Description

Известен способ получени  тритиоалкиловых эфиров ортомуравьиной кислоты путем взаимодействи  безводной муравьиной кислоты с меркаптанами.A known method for producing orthoformic acid tritioalkyl esters by reacting anhydrous formic acid with mercaptans.

Известные способы имеют тот недостаток, что они мало производительны или сложны по выполнению.Known methods have the disadvantage that they are of little productive or difficult to implement.

Предложен способ получени  тритиоэтиловых эфиров ортомуравьиной кислоты путем взаимодействи  триэтилового эфира ортомуравьиной кислоты с этилмеркаптаном:A method has been proposed for the preparation of tritioethyl esters of ortruvic acid by reacting orthruvic triethyl ester with ethyl mercaptan:

СН(ОС2Н5)з SQHsSH СН(5С2Н5)з.CH (OC2H5) s SQHsSH CH (5C2H5) z.

Очевидно, что таким способом можно получать и другие тиоалкиловые эфиры ортомуравьиной кислоты.It is obvious that in this way other thioalkyl esters of orthoformate acid can be obtained.

Предлагаемый способ отличаетс  от известного тем, что реакции взаимодействи  подвергают меркаптан с триэтиловым эфиром ортомуравьиной кислоты; предлагаемый способ  вл етс  более производительным .The proposed method differs from the known one in that the reactions of interaction are subjected to mercaptan with orthoformic acid triethyl ester; The proposed method is more productive.

Пример. Смесь 4,7 г (0,03 м) триэтилового эфира ортомуравьиной кислоты И 11,2 г (0,18 м этилмеркаптана нагревают в ампуле при 120-130° в течение 24 час. Разгонкой выделено 1,2 г исходного эфира и 4,0 г (87% от теоретического) тритиоэтилового эфира ортомуравьиной кислоты.Example. A mixture of 4.7 g (0.03 m) of trialkyl ester of orthmicryl acid and 11.2 g (0.18 m of ethyl mercaptan is heated in a vial at 120–130 ° for 24 hours. 1.2 g of the starting ether and 4 are separated by distillation 0 g (87% of theoretical) tritioethyl ester of ortoformic acid.

При сулемовом титровании: на 0,1973 г вещества пошло 30,00 мл 0,1 N.NaOH, что соответствует 99,54% тритиоэфира; на 0,1737 г вещества пощло 26,48 жл 0,1 N.NaOH, что соответствует 99,81% тритиоэфира.In the case of sublimate titration: 30.00 ml 0.1 N.NaOH, which corresponds to 99.54% tritioether, went to 0.1973 g of the substance; per 0.1737 g of substance, 26.48 gallons of 0.1 N.NaOH was obtained, which corresponds to 99.81% of tritioether.

№ 138248- 2 Предмет изобретени No. 138248- 2 The subject invention

Способ получени  тритиоалкиловых эфлрав ортомуравьиной кислоты из меркаптанов, отличающийс  тем, что, с целью увеличени  производительности процесса, меркаптаны подвергают взаимодействию с триэтиловым эфиром ортомуравьиной кислоты.The method of producing orthoformic tritioalkyl effluents from mercaptans, characterized in that, in order to increase the productivity of the process, the mercaptans are reacted with ortoformate triethyl ester.
