Изобретение относитс к области получени высншх алкадиинов-1,3 общей формулы R - , где R - неразветвленный алкил.The invention relates to the field of producing alkynium-1,3-higher alkanes of general formula R -, where R is unbranched alkyl.
Указанные диацетилены вл ютс исходными соединени ми дл синтеза биологически активных препаратов.These diacetylenes are the starting compounds for the synthesis of biologically active preparations.
Известен способ получени алкадиинов-1,3 щелочным расщеплением диацетиленовых спиртов 1.A known method for the preparation of alkadines-1,3 by alkaline cleavage of diacetylene alcohols 1.
Недостатком способа вл етс мала доступность исходных днацетиленовых спиртов.The disadvantage of this method is the low availability of the starting bottom acetylene alcohols.
Известен способ получени высщих алкадиннов-1 ,3 путем алкилировани галоидным алкнлом диацетнленида натри в жидком аммиаке при температуре -40°С 2. Однако при этом образуютс незначительное количество высщих алкадиинов-1,3.A known method of producing high alkadinos-1, 3 by alkylation with a halide alkali of sodium diacetnenide in liquid ammonia at a temperature of -40 ° C. 2 However, an insignificant amount of high alkadiins-1,3 is formed.
Целью изобретени вл етс повыщение выхода высщих алкадиииов-1,3.The aim of the invention is to increase the yield of higher alkadia-1,3.
Поставленна пель достигаетс описанным способом получени алкадиииов-1,3, заключающимс в том, что алкилироваиие диацетиленида натри бромистым алкилом провод т в среде апротоиного органического растворител при 20-60°С в присутствии жидкого аммиака с дегазацией последнего в атмосфере инертного газа.The delivered pellet is obtained by the described method of preparing alkadium-1,3, which implies that the alkylating of sodium diacetylide with alkyl bromide is carried out in aprilo organic solvent at 20-60 ° C in the presence of liquid ammonia with degassing of the latter in an inert gas atmosphere.
Отличнем способа вл етс проведение процесса в среде органического апротоиного растворнтел при 20-60С с дегазацией аммиака в атмосфере инертного газа.An excellent method is to carry out the process in an organic apotoin solvent at 20–60 ° C with ammonia degassing in an inert gas atmosphere.
В качестве апротонного органического растворител преимущественно используют диметил формамид или диметнлсульфоксид.Dimethyl formamide or dimethyl sulfoxide is preferably used as the aprotic organic solvent.
