Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of hydrodechlorinating chloroaromatic compounds through their reaction with hydrogen in a flow system in the presence of a catalyst while heating. The method is characterised by that the catalyst used is a metal-carbon composite which is in form of 3-10 nm nickel particles, tightly and completely coated with a 0.5-2 nm thick carbon layer. The heating temperature is equal to 75-350C. ^ EFFECT: invention lowers the reaction temperature for hydrodechlorination of chloroaromatic compounds while preserving catalyst efficiency and stability. ^ 1 cl, 5 ex, 4 tbl Изобретение относится к способу гидродехлорирования хлорароматических соединений путем их взаимодействия с водородом в проточной системе в присутствии катализатора при нагреве, характеризующемуся тем, что в качестве катализатора используют металл-углеродный композит, представляющий собой частицы никеля размером 3-10 нм, плотно полностью покрытые слоем углерода толщиной 0,5-2 нм, а температура нагрева составляет 75-350°С. Применение настоящего способа позволяет снизить температуру реакции гидродехлорирования хлорароматических соединений при сохранении эффективности и стабильности работы катализатора. 4 табл.
