Description
Известны многочисленные способы получени фумаровон и маленновой кислот, а также ангндрнда последней. Часть способов основана на химических превращени х соедгшений, уже содержащих из четырех атомов углерода, включа Д1зе карбоксильные группы. Сюда, например, относитс сиитез названных выше вен1,еств из моно-п днгалогено-н окси- итарных кислот, из ацетилепднкарбоновой кислоты и др.Numerous methods are known for the preparation of fumaric and maleic acids, as well as angndrnda. Some of the methods are based on chemical transformations of compounds already containing four carbon atoms, including carboxy groups. This includes, for example, the location of the veins mentioned above, of mono-n hydroxyalkanoic hydroxy acids, acetyl neptonic carboxylic acid, and others.
Особо важное промышлепное значение имеет сиитез маленпового ангидрида, а также малеиновой и фумаровой кпслот, путем каталцтичеекого окислени ароматических углеводородов (бензола, толуола, нафталина и т. п.), производных фурапа, парафинов, моно- и ди-олефн ,ювых углеводородов с числом атомов углерода более четырех и др.Especially important industrial importance is the sietez of malenpoic anhydride, as well as maleic and fumaric klslot, by catalytic oxidation of aromatic hydrocarbons (benzene, toluene, naphthalene, etc.), derivatives of furap, paraffins, mono- and di-olefn, with hydrocarbons, with the number more than four carbon atoms, etc.
В св зи с задачами синтеза искусственных материалов представл ет интерес разработка новых способов получени фумаровой и маленновой кислот-исходных продукте; дл пропзвс.тства пластических масс (пенопластов), синтетических волскон, красителей, пластификаторов и других важных химическ 1Х продуктов.In connection with the problems of synthesizing synthetic materials, it is of interest to develop new methods for the production of fumaric and malennova acids; for production of plastics, synthetic fibers, dyes, plasticizers and other important chemical 1X products.
Предлагаетс способ получени одной из указанных кислот, а именно , фумаровой путем нагревани 1,4-динитробутепа-2, получаемого, папримсф нитрованием дивинила с разбавленной минеральной кислотой. При этом обе нитрометильные группы легко превращаютс в карбоксильные с образовапнем фумаровой кислоты по схеме.A method is proposed for the preparation of one of these acids, namely, fumaric acid by heating 1,4-dinitrobutypa-2, obtained by adding nitration of divinyl with a diluted mineral acid. In this case, both nitromethyl groups are easily converted to carboxyl groups with the formation of fumaric acid according to the scheme.

Пример. В круглодонную колбу емкостью 50 мл, снабженную мешалкой и-обратным холодильником, загружают 2,92 г 1,4-динитробутена-2 и 20-30 мл разбавленной (1:1) сол ной кислоты. Реакционную массу кип т т 2-3 час. После окончани выдержки добавл ют небольшое количество активированного угл , гор чий раствор фильтруют, а выделившийс из фильтрата белоснежный кристаллический осадок фумаровой кислоты отсасывают и промывают небольшим количеством холодной воды- Выход 1,2-1,5 г.Example. A 50 ml round bottom flask equipped with a stirrer and reflux condenser was charged with 2.92 g of 1,4-dinitrobutene-2 and 20-30 ml of diluted (1: 1) hydrochloric acid. The reaction mass is boiled for 2-3 hours. After the end of the aging, a small amount of activated carbon is added, the hot solution is filtered, and the white crystalline precipitate of fumaric acid precipitated from the filtrate is sucked off and washed with a small amount of cold water. Yield 1.2-1.5 g
