Description
Способ получени узких фракций парафиновых утеводородов через образование комплекса карбамида с исходной смесью углеводородов и с последующим разложением комплекса постеленным повышением температуры в среде растворител известен.The method of obtaining narrow fractions of paraffin utensils through the formation of a urea complex with an initial mixture of hydrocarbons and with the subsequent decomposition of the complex by increasing the temperature in a solvent medium is known.
Предложенный способ получени узких фракций парафиновых углеводородов из исходной смеси углеводородов, св занных в комплексе с карбамидом и последующим разложением комплекса растворителем (водой или бензином), отличаетс тем, что разделение парафиновых углеводородов на узкие фракции провод т путем разложени комплекса по част м посредством последовательного введени в него растворител отдельными дозами. Комплексы, образованные кристаллическим карбамидом или водным и спиртовым растворами его, разлагаютс путем введени небольших доз растворител (воды или бензина) при посто нной невысокой температуре (30-40°). В результате такого последовательного разложени комплекса получаютс отдельные узкие сЬоакции нормальных парафиновых углеводородов со следуюш,ей характеристикой: т. пл. от +18 до -36°; уд. вес от 0,7819 до 0,8466; коэффициент рефракции от 1,4380 до 1,4440.The proposed method of obtaining narrow fractions of paraffin hydrocarbons from the initial mixture of hydrocarbons associated with urea and subsequent decomposition of the complex with a solvent (water or gasoline) is characterized in that the separation of paraffin hydrocarbons into narrow fractions is carried out by decomposing the complex in parts by sequential introduction it is a solvent in separate doses. Complexes formed by crystalline urea or water and alcohol solutions of it are decomposed by the introduction of small doses of solvent (water or gasoline) at a constant low temperature (30-40 °). As a result of such sequential decomposition of the complex, separate narrow campaigns of normal paraffin hydrocarbons are obtained with the following, her characteristic: mp. from +18 to -36 °; beats. weight from 0.7819 to 0.8466; refractive index from 1.4380 to 1.4440.
Последовательный вывод из зоны разложени комплекса выдел ющихс порций н-парафиновых углеводородов позвол ет получать отдельные узкие фракции их.Sequential removal from the decomposition zone of the complex of evolved portions of n-paraffin hydrocarbons allows to obtain separate narrow fractions of them.
Количество фракций, а также более широкий или более узкий их фракционный состав, зависит прежде всего от количества воды, подаваемой в виде отдельных доз на разложение комплекса. Измен количество воды во врем .подачи ее на разложение комплекса, можно получить узкие фракции н-парафиноЕЫХ углеводородов заданного качества .The number of fractions, as well as their broader or narrower fractional composition, depends primarily on the amount of water supplied in the form of individual doses to the decomposition of the complex. By changing the amount of water during its supply to the decomposition of the complex, it is possible to obtain narrow fractions of n-paraffin hydrocarbons of a given quality.
