Изобретение относитс к способу получени хлорметилнитраминов, которые могут быть использованы в качестве промежуточных продуктов в органическом синтезе дл получени различных классов органических веществ.The invention relates to a process for the preparation of chloromethyl nitramines, which can be used as intermediates in organic synthesis for the production of various classes of organic substances.
Известен способ получени хлорметилнитраминов путем взаимодействи хлористого водорода или ацетилхлорида и эфира нитраминометилолов .A method of producing chloromethylnitramines is possible by reacting hydrogen chloride or acetyl chloride and an ether of nitraminomethylols.
Однако эфиры нитраминометилолов труднодоступны .However, the nitraminomethylol esters are not readily available.
С целью упрои1,ени технологического пропесса предлагаетс новый способ нолучепи хлорметилнитраминов, заключающийс в том, что первичный нитромип обрабатывают парафином и хлористым тионилом с последующим выделепием пелевого продукта известным способом . Процесс провод т в присутствии или отсутствии серной кислоты или хлористого цинка преимуществе1П1о при 15-60°С и в среде инертного органического растворител .In order to improve the technological process, a new method is proposed for the synthesis of chloromethylnitramines, which means that the primary nitromip is treated with paraffin and thionyl chloride, followed by isolation of the pellet product in a known manner. The process is carried out in the presence or absence of sulfuric acid or zinc chloride with an advantage of 1P1o at 15-60 ° C and in an inert organic solvent.
Пример 1. 1-Хлор-2-нитро-2-азапропан.Example 1. 1-Chloro-2-nitro-2-azapropane.
Раствор 7,5 г метилнитрамииа, 4,0 г параформа и 12,0 г хлористого тиопила в 15 мл дихлорэтана перемешивают в течепие 5- 10 мип при 20°. После отгонки легколетучих веществ и перегопки остатка получают 11,2 г (90% от теоретического) вещества с т. кип. 61°/4 мм рт. ст.; по 1,4829; 1,3735.A solution of 7.5 g of methylnitramia, 4.0 g of paraform and 12.0 g of thiopyl chloride in 15 ml of dichloroethane are stirred for 5-10 min at 20 °. After distillation of volatile substances and reheating of the residue, 11.2 g (90% of the theoretical) of the substance with the bale are obtained. 61 ° / 4 mmHg v .; on 1,4829; 1.3735.
Аналогично получают 1-хлор-2-нитро-2-азапентеп и 1,10-дихлор-2,9-дипитро-2,9-Д1иазадекан с выходами 89 и 90% соответственно.Similarly, 1-chloro-2-nitro-2-azapentep and 1,10-dichloro-2,9-dipitro-2,9-Dilazadecane are obtained in 89 and 90% yields, respectively.
Пример 2. 1,6-Дихлор-2,5-дииитро-2,5диазагексан .Example 2. 1,6-Dichloro-2,5-diitro-2,5 diazazhexane.
При взаимодействии 7,5 г этилендинитрамииа , 3,9 г параформа, 16,0 г хлористого тионила в 15 мл днхлорэтапа в присутствии 0,2 г серпой кислоты или хлористого иинка после выделени обычными приемамп получают вещество в количестве 8,8 г (73% от теоретического ) с т. пл. 103-104°С.By reacting 7.5 g of ethylenedinitramia, 3.9 g of paraform, 16.0 g of thionyl chloride in 15 ml of dynorotephapa in the presence of 0.2 g of sickle acid or chloride, after separation by ordinary methods, a substance is obtained in an amount of 8.8 g (73% from theoretical) with t. pl. 103-104 ° C.
