Description
Известен способ нитровани третичного бутилметилового эфира метакрезола дл получени мускус-амбрета в среде уксусного ангидрида, как водоотнимающего средства. При этом реакци завершаетс при нагревании , что приводит к бурному выделению окислов азота, которые отравл ют воздух и вызывают коррозию аппаратуры.A known method for the nitration of tertiary butyl methyl ether of m-cresol to produce musk ambret in acetic anhydride medium as a dehydrating agent. In this case, the reaction is completed by heating, which leads to a rapid release of nitrogen oxides, which poison the air and cause corrosion of the apparatus.
Предлагае.мый способ значительно улучшает услови труда и отличаетс от известных тем, что процесс нитровани провод т на холоду в присутствии кислого сернокислого кали или натри . Выход нитронродукта и его качество остаютс такими же как и при проведении процесса при нагревании.The proposed method significantly improves the working conditions and differs from the known ones in that the nitration process is carried out in the cold in the presence of potassium or sodium sulphate. The yield of the nitrone product and its quality remain the same as when the process is carried out with heating.
Пример. К 100 вес. ч. уксусного ангидрида, охлажденного до температуры минус 5-6°, приливают 134 вес. ч. азотной кислоты ( ,51 -1,52). К приготовленной смеси добавл ют 2 вес. ч. тонкорастертого кислого сернокислого кали Example. To 100 weight. including acetic anhydride, cooled to a temperature of minus 5-6 °, poured 134 weight. including nitric acid (, 51 -1.52). To the prepared mixture was added 2 wt. including finely powdered acid potassium sulphate
или натри , а затем постепенно, соблюда температуру минус 5-6°, ввод т 100 вес. ч. третичного бутилметилового эфира метакрезола в 76 вес. ч. уксусного ангидрида и перемешивают .or sodium, and then gradually, observing the temperature minus 5-6 °, 100 weight is introduced. including tertiary butyl methyl ether metacresol in 76 weight. including acetic anhydride and mix.
В процессе реакции из аппарата берзт пробы. Когда вз та проба при выливании в холодную воду застынет и не даст масл нистого продукта , пере.мешивание заканчивают, реакционную массу выливают на лед и обрабатывают известными способами. Процесс нитровани продолжаетс 15-18 часов.In the process of reaction from the apparatus berzt samples. When the sample is taken to freeze when it is poured into cold water and does not give an oily product, the stirring is finished, the reaction mixture is poured onto ice and treated by known methods. The nitration process lasts 15-18 hours.
