Изобретение относитс к области нолучени органических соединений фосфора, а именно к способу получени новых аммониевых солей высших моноалкилфосфористых кислот.The invention relates to the field of the production of organic phosphorus compounds, namely, to a process for the preparation of new ammonium salts of higher monoalkylphosphorous acids.
Эти соединени могут быть использованы в качестве полупродуктов в химии фосфороргаиических соединений.These compounds can be used as intermediates in the chemistry of phosphorus compounds.
Известны способы получени аммониевых солей низших моноалкилфосфористых кислот взаимодействием соответствующих моноили диалкилфосфористых кислот с аммиаком. Однако этот способ мало пригоден дл синтеза высших производных из-за малой доступности реагентов.Methods are known for the preparation of ammonium salts of lower monoalkylphosphorous acids by reacting the corresponding mono or dialkylphosphorous acids with ammonia. However, this method is not suitable for the synthesis of higher derivatives due to the low availability of reagents.
Аммониевые соли высших моноалкилфосфористых кислот не описаны.Ammonium salts of higher monoalkylphosphorous acids are not described.
Способ их получени основан на известной реакции переэтерификации эфиров фосфористой кислоты, котора , однако, ранее не примен лась дл синтеза аналогичных соединений .The method for their preparation is based on the known transesterification of phosphorous acid esters, which, however, has not previously been used for the synthesis of analogous compounds.
По предлагаемому, способу аммониевую соль монометилфосфористой кислоты подвергают переэтернфикации высшим спиртом желательно при нагревании до 150-220°С с одновременной отгонкой образующегос в реакции метанола.According to the proposed method, the ammonium salt of monomethyl phosphorous acid is subjected to re-internation with higher alcohol, preferably when heated to 150-220 ° C with simultaneous distillation of the methanol formed in the reaction.
Контроль за ходом реакции провод т по выделению метанола. Исходные продукты предпочтительно брать в эквимольных количествах .Monitoring the progress of the reaction is carried out by the release of methanol. The initial products are preferably taken in equimolar amounts.
Целевые продукты выдел ют известными приемами, выход практически количестзеиный .Target products are isolated by known methods, the yield is almost quantitative.
Полученные соединени охарактеризованы физико-химическими константами, их строение подтверждено элементным анализом.The obtained compounds were characterized by physicochemical constants, their structure was confirmed by elemental analysis.
В качестве исходной аммониевой соли монометилфосфористой кислоты можно использовать продукт взаимодействи эквимольных количеств диметилфосфита и хлористого аммони , получаемый нагреванием смеси реагентов до 120-150°С предпочтительно в расплаве аммониевой соли монометилфосфористой кислоты.As a starting ammonium salt of monomethyl phosphorous acid, you can use the product of the interaction of equimolar amounts of dimethyl phosphite and ammonium chloride, obtained by heating the mixture of reagents up to 120-150 ° C, preferably in a molten ammonium salt of monomethyl phosphorous acid.
Пример 1. Получение аммониевой соли моноцетилфосфористой кислоты.Example 1. Obtaining the ammonium salt of mono-acetylphosphorous acid.
Смесь 0,1 г-моль аммониевой соли монометилфосфористой кислоты и 0,1 г-моль цетилового спирта нагревают с перемешиванием при 175-190°С до прекращени выделени метилового спирта (4-6 час). Реакционную массуA mixture of 0.1 g mol of ammonium salt of monomethyl phosphorous acid and 0.1 g mol of cetyl alcohol is heated with stirring at 175-190 ° C until the release of methyl alcohol is stopped (4-6 hours). Reaction mass
вакуумируют и в остатке с выходом 100% получают вещество в виде белых кристаллов; т. пл. 68-70°С.vacuum and in the residue with a yield of 100% get the substance in the form of white crystals; m.p. 68-70 ° C.
