Description
Фенолы, крезолы ксиленолы и другие фенольные продукты получаемые из смолы от полукоксовани бурого угл , из бурого угл при деструктивном гидрировании, а также фенольные воды, полученные при облагораживании бурого угл , содержат органические соединени серы, придающие им крайне непри тный запах, что затрудн ет их дальнейшую переработку.Phenols, cresols, xylenols, and other phenolic products derived from tar from the coking of brown coal, from brown coal during destructive hydrogenation, and the phenolic waters obtained by refining brown coal contain organic sulfur compounds, which give them an extremely unpleasant odor, which makes them difficult further processing.
Описываемое изобретение позвол ет очищать указанные продукты путем обработки раствором углекислых солей щелочных металлов под давлением и при повышенной температуре , с применением способа, описанного в авт. св. № 110178.The described invention makes it possible to purify these products by treating with a solution of alkali metal carbonate salts under pressure and at elevated temperature, using the method described in ed. St. No. 110178.
Пример 1. Фенол из смолы, полученной при полукоксовании бурого угл , содержащий 0,015% серы , обрабатывают в аппарате, описанном в авт. св. № 110178, при давлении 10 атм и температуре 180° 3-4-кратным количеством раствора углекислого кали или натри приблизительно 10%-ной концентрации. Фенол тный щелок, который отвод т из нижней части аппарата, подвергают карбонизации углекислотой (освобожденной во врем процесса) под давлением и выдел ющийс фенол подвергают перегонке. Полученный после перегонки фенол содержит 0,003 % серы и может быть использован дл различных целей, в том числе и дл гидрировани на никелевом катализаторе в циклогексанол .Example 1. Phenol from the resin obtained by semi-coking of brown coal, containing 0.015% of sulfur, is treated in the apparatus described in ed. St. No. 110178, at a pressure of 10 atm and a temperature of 180 °, with a 3-4-fold amount of a solution of potassium carbonate or sodium of approximately 10% concentration. Phenolic liquor, which is removed from the bottom of the apparatus, is carbonized with carbon dioxide (released during the process) under pressure and the liberated phenol is subjected to distillation. The phenol obtained after distillation contains 0.003% sulfur and can be used for various purposes, including hydrogenation on a nickel catalyst to cyclohexanol.
Пример 2. Крезоловую фракцию с содержанием серы 0,053%, полученную из облагороженных продуктов бурого угл , обрабатывают , как описано в примере 1- Получают крезол с содержанием 0,017% серы, пригодный дл получени высококачественного трикрезолфосфата .Example 2. A cresol fraction with a sulfur content of 0.053%, obtained from the refined brown coal products, is treated as described in Example 1- Cresol is obtained with a content of 0.017% sulfur, suitable for obtaining high-quality tricresol phosphate.
