Description
В ОСНОВНОМ авт. св. N° 66043 описываетс способ по.пучени метнлсульфо .метилата К1М-ди(4-дппропил-амиио-фенил)-мочевины нз соответствующего производного мочевины и дипрои 1л-сульфата.BASIC Auth. St. N ° 66043 describes a method for the synthesis of methyl sulfonic methylate K1M-di (4-dipropyl-amiophenyl) urea from the corresponding urea derivative and diproyl l-sulfate.
Предлагаемый способ получени метил-сульфо-метилата .К-д;1 (4-диметил-амино-фенил)-мочевины из .-ди(4-диметил-амино-фенил) .чочевины и диметил-сульфата осуществл етс возде1 |ствием диметилсульфата на раствор Х1К-ди(4-дИ)Мет 1л-амино-фенил)-мочевины в бензине , нитробензоле или в каком-либо другом органическом растворителе .The proposed method for the production of methyl sulfo-methylate. K-d; 1 (4-dimethyl-amino-phenyl) -urea from.-Di (4-dimethyl-amino-phenyl). Urea and dimethyl-sulphate on a solution of H1K-di (4-di) Meth 1l-amino-phenyl) -urea in gasoline, nitrobenzene or in some other organic solvent.
Пример. 3 г NN-ди (4-диметил-амино-фенил)-мочевины- нагревают при перемещивании с 10 .ил бензола и 2,5 г диметил-сульфата На кип щей вод ной бане в течение 3 час. Выпавщие кристаллы отсасывают , промывают спиртом и эфиром и кристаллизуют из метилового спирта.Example. 3 g of NN-di (4-dimethyl-amino-phenyl) -urea are heated with transferring from 10. Of benzene and 2.5 g of dimethyl sulphate in a boiling water bath for 3 hours. The precipitated crystals are filtered off with suction, washed with alcohol and ether, and crystallized from methyl alcohol.
