Description
Известен способ получени пирофосфатов и пирофосфонатоБ гидролизом эфирохлорангидридов кислот п тивалентного фосфора.A known method for the preparation of pyrophosphates and pyrophosphonatoB by the hydrolysis of esters of hydrochloride anhydrides of pivalent phosphorus.
Дл упрощени способа предлагаетс получать пирофосфаты и пирофосфонаты последовательной обработкой дихлорангидридов фосфиновых кислот, или алкилдихлорфосфатов , или хлорокиси фосфора водой в соотношении 0,5 : 1, а затем спиртом в соотношении соответственно 1 : 1 или 2 : 1 в присутствии веш ,еств основного характера, например триэтиламина , при пониженной температуре.To simplify the process, it is proposed to prepare pyrophosphates and pyrophosphonates by sequential treatment of phosphinic acid dichlorides, or alkyl dichlorophosphates, or phosphorus oxychloride, with a ratio of 0.5: 1, and then with an alcohol in the ratio of 1: 1 or 2: 1, respectively, in the presence of basic substances. for example, triethylamine, at a lower temperature.
Пример 1. К раствору 13,3 г метилдихлорфосфиноксида в 100 мл сухого четыреххлористого углерода или другого инертного растворител при - 30-20°С и перемешивании медленно прибавл ют смесь 0,9 г воды и 10,1 г триэтиламина, а затем при постепенном повышении температуры до - 10° смесь 4,6 г абс. этанола и 10,1 г триэтиламина. Продолжа перемешивание, реакционную массу довод т до комнатной температуры, отдел ют осадок хлоргидрата амина, удал ют растворитель и остаток перегон ют в вакууме. Получают 8,06 г (70%) О,О-диэтилметилпирофосфоната . Т. кип. 96-97° (0,3 мм рт. ст.), п 1,4340.Example 1. To a solution of 13.3 g of methyldichlorophosphine oxide in 100 ml of dry carbon tetrachloride or another inert solvent at a temperature of 30–20 ° C and a stirring, slowly add a mixture of 0.9 g of water and 10.1 g of triethylamine, and then with a gradual increase temperatures up to - 10 ° a mixture of 4.6 g abs. ethanol and 10.1 g of triethylamine. Continuing the stirring, the reaction mass is brought to room temperature, the precipitate of amine hydrochloride is separated, the solvent is removed and the residue is distilled in vacuum. 8.06 g (70%) O, O-diethylmethyl pyrophosphonate are obtained. T. Kip. 96-97 ° (0.3 mm Hg. Art.), P 1.4340.
чают тетраэтилпирофосфат с выходом . Т. кип. 104-105° (0,1-0,2 мм рт. ст.), 1,4164.tetraethyl pyrophosphate is given in the yield. T. Kip. 104-105 ° (0.1-0.2 mm Hg. Art.), 1.4164.
Литературные данные: Т. кип. 140 (2 мм рт. ст.), п2о 1,4182.Literary data: T. Kip. 140 (2 mm of mercury.), P2o 1,4182.
Пример 3. Таким же образом, как в примере 1, тетраэтилпирофосфат получают из POCls обработкой в указанных выше услови х смесью 0,5 моль воды с 1 моль триэтиламипа , а затем смесью 2 моль спирта и 2 моль триэтиламина. Т. кип. 104-105° (0,1 - 0,2 мм рт. ст.), п2о 1,4169.Example 3. In the same manner as in Example 1, tetraethyl pyrophosphate is obtained from POCls by treating under the above conditions a mixture of 0.5 mol of water with 1 mol of triethylamine and then a mixture of 2 mol of alcohol and 2 mol of triethylamine. T. Kip. 104-105 ° (0.1 - 0.2 mm Hg. Art.), P2o 1.4169.
