За влено 19 ма 1939 года в НКПП за Х 2025. Опубликовано 31 июл 1940 года.It was filed on May 19, 1939 in the NCPP for X 2025. Published July 31, 1940.
предлагаемое изобретение относитс к гидрированию касторового масла с целью получени материала с высокими диэлектрическими свойствами дл пропитки конденсаторов и т. п.The present invention relates to the hydrogenation of castor oil in order to obtain a material with high dielectric properties for impregnation of capacitors, etc.
Было найдено, что дл получени продукта с высокими диэлектрическими свойствами из касторового масла путем его гидрировани необходимо процесс вести в направлении насыщени водородом двойных св зей ридинолевой кислоты при минимальном восстановлении гидроксильных групп.It has been found that in order to obtain a product with high dielectric properties from castor oil by hydrogenating it, the process must be conducted in the direction of hydrogenation of the double bonds of rinidolic acid with minimum reduction of hydroxyl groups.
Получение препарата с сохранением ацетильного числа и определенной кристаллической структуры требует условий, при которых температура и врем гидрогенизации касторового масла до полного насыщени его были бы минимальными. Однако, понижение температуры и сокращение времени гидрогенизации при применении обычных методов не давало желательных результатов. Поэтому был разработан способ гидрогенизации , при котором понижение температуры гидрогенизации компенсируетс применением высокоактивных катализаторов, а самый процесс ведетс в услови х, которые позвол ютPreparation of the drug with preservation of the acetyl number and a certain crystalline structure requires conditions under which the temperature and time of hydrogenation of castor oil to its full saturation would be minimal. However, lowering the temperature and reducing the time of hydrogenation when using conventional methods did not give the desired results. Therefore, a hydrogenation method was developed, in which the lowering of the hydrogenation temperature is compensated by the use of highly active catalysts, and the process itself is conducted under conditions that allow
T::::;:-:C::A:I Г-,ОД::О-,Г:АT ::::;: -: C :: A: I G-, OD :: O-, G: A
сохранить гидроксильные группы в глицеридах.retain hydroxyl groups in glycerides.
Дл приготовлени высокоактивного катализатора целесообразно примен ть сплав никел с алюминием, лучше с добавкой кобальта. При обработке этого сплава раствором щелочи алюминий, как известно, выщелачиваетс и получаетс весьма активный катализатор.To prepare a highly active catalyst, it is advisable to use an alloy of nickel with aluminum, preferably with the addition of cobalt. When this alloy is treated with an alkali solution, aluminum is known to be leached and a very active catalyst is obtained.
Процесс гидрогенизации целесообразно проводить в автоклаве, снабженном мещалкой.The hydrogenation process is advisable to carry out in an autoclave equipped with a broom.
Гидрогенизаци ведетс при температурах пор дка 140-150° с давлением внутри автоклава 35-40 атм. до получени конечного продукта с температурой плавлени не ниже 7У и йодным числом не выще 8. Водород подаетс на „насыщение, т. е. избыточный водород из автоклава не выпускаетс в атмосферу (только в начале и в конце процесса в течение короткого промежутка времени даетс кратковременна продувка).Hydrogenation is carried out at temperatures of the order of 140-150 ° C with a pressure inside the autoclave of 35-40 atm. until the final product is obtained with a melting point not lower than 7 ° C and iodine number is not less than 8. Hydrogen is supplied to saturation, i.e. excess hydrogen from the autoclave is not released into the atmosphere (only at the beginning and at the end of the process for a short period of time purge).
в результате после механической очистки продукта гидрогенизации от катализатора (с помощью обычной фильтрации) получаетс материал, обладающий высокими диэлектрическими свойствами, необходимыми дл пропиточного препарата.As a result, after mechanical purification of the hydrogenation product from the catalyst (using conventional filtration), a material is obtained that has the high dielectric properties necessary for the impregnating preparation.
