Description
Выделение фенолов из дегтей, полученных из топлива, содержащего азот (торф, бурые угли, каменные угли), приводит к получению продукта,, содержащего как фенолы, так и азоти1стые основани . Фенолы обладают сиособностью давать с основани ми прочные комплексные соединени . Р д этих комплексных соединений не разрушаютс ни щелочами, ни кислотами.Separation of phenols from tar obtained from a fuel containing nitrogen (peat, brown coal, coal), results in a product containing both phenols and nitrogen bases. Phenols have the ability to produce strong complex compounds with bases. A number of these complex compounds are not destroyed by alkalis or acids.
Известные способы очистки дегтей от фенолов не дают возможности получить фенолы, свободные от примесей и азотистых оснований . Вследствие этого использование фенолов в ответственных производствах (пластмассы, синтез и др.) сопр жено с р дом существенных трудностей, и качество получеииых продуктов оказываетс низким.Known methods of purification of tar from phenols do not allow to obtain phenols, free from impurities and nitrogenous bases. As a result, the use of phenols in critical industries (plastics, synthesis, etc.) is associated with a number of significant difficulties, and the quality of the products obtained is low.
Оиисываемый способ очистки дсстиллатов дегтей от фенолов и оснований путем промьижн их раствором едкого натра и слабым раствором серной кислоты предотвращает реакпии конденсации феиолов с основани ми. Особенность способа заключаетс в том, что отогнанные фракции дегтей обрабатывают раствором щелочи или кислоты, ие позднее чем через 5мин после их отгонки.The cleaning method for cleaning dstillate tar from phenols and bases by using them with caustic soda solution and a weak solution of sulfuric acid prevents condensation reactions of feiols with bases. The peculiarity of this method is that the distilled fractions of tar are treated with a solution of alkali or acid, no later than 5 minutes after their distillation.
Пользу сь этим способом и подверга свеженолученные дестиллаты (лучще всего в мо.мент их конденсации) обработке серной кислотой получают фракцию фенолов, содержащую от 0,02 до 0,3% примесей .Using this method and subjecting the newly obtained distillates (best of all to their condensation) with a treatment with sulfuric acid, a fraction of phenols containing from 0.02 to 0.3% of impurities is obtained.
Пример. ФенолЕзГ, выделенные нз масел, разогнанных за 10 дней, показывают содержание примесей в их дестиллатах-1,5%, 1,8%, 2,5%. Фенолы, полученные из масел, промытых кислотой в момент конденсации, показывают содержание примесей в дестиллатах-- 0,002%, 0,027%, 0,30/0N° 85571,- 2 -Example. Phenol-EG, isolated from the oils dispersed in 10 days, shows the content of impurities in their distillates, 1.5%, 1.8%, 2.5%. Phenols obtained from oils washed with acid at the time of condensation show the content of impurities in distillates - 0.002%, 0.027%, 0.30 / 0N ° 85571, - 2 -
Предмет изобретени Subject invention
Способ очистки дестиллатов дегтей от фенолов и оснований путей иромывки их раствором едкого натра и слабым раствором серной кислоты, отличающийс тем,, что, с целью иредотвращени реакции конденсации фенолов с основани ми, отогнанные фракции дегтей обрабатывают раствором щелочи или кислоты, не нозднее чем через 15 мим после нх отгонки.The method of purification of distillates of tar from phenols and bases of the paths and washing them with sodium hydroxide solution and a weak solution of sulfuric acid, characterized in that, in order to prevent the condensation reaction of phenols with bases, the distilled fractions of tar are treated with an alkali or acid solution more than 15 mime after nh distillation.
