Description
с Кроме того, ири употреблении предлагаемого катализатора снижаетколичество образующихс побочных продуктов.c In addition, the use of the proposed catalyst reduces the amount of by-products formed.
№ 125247No. 125247
Дл приготовлени катализатора смешивают равные объемы насыщенных растворов алюмокалиевых квасцов и медного купороса и приливают полученную смесь к равному же объему измельченной пемзы с размером зерен 2-3 мм. Смесь кип т т до удалени воздуха и затем, продолжа кип чение, приливают раствор соды до щелочной реакции, продолжают кип чение еще 2-3 ч, после чего с.чивают жидкость, промывают катализатор водой и высушивают в токе метана при 300-400°.To prepare the catalyst, equal volumes of saturated solutions of potassium alum and copper sulfate are mixed and the resulting mixture is poured to an equal volume of crushed pumice with a grain size of 2-3 mm. The mixture is boiled until air is removed and then, continuing to boil, the soda solution is poured until alkaline, boiling is continued for another 2-3 hours, after which the liquid is pumped, the catalyst is washed with water and dried in a stream of methane at 300-400 ° .
Приготовленный катализатор загружают в кварцевую трубу, помещепную в электрическую печь, и пропускают смесь метана и брома в мол рном отношении 10: 1 при температуре 380 с такой скоростью, чтобы врем пребывани газов в реакционной зоне составл ло 0,6 мин. Результаты приведены в таблице (см. выше).The prepared catalyst is loaded into a quartz tube placed in an electric furnace, and a mixture of methane and bromine is passed in a molar ratio of 10: 1 at a temperature of 380 at a rate such that the residence time of the gases in the reaction zone is 0.6 minutes. The results are shown in the table (see above).
