KATALYSATOR ZUR DEHYDRIERUNG VON SAUERSTOFFHALTIGEN DERIVATEN DER CYCLOHEXANREIHE ZU DEN ENTSPRECHENDEN CYCLISCHEN KETONEN UND/ODER PHENOLEN UND VERFAHREN ZUR DEHYDRIERUNG VON SAUERSTOFFHALTIGEN DERIVATEN DER CYCLOHEXANREIHE ZU DEN ENTSPRECHENDEN CYCLISCHEN KETONEN UND/ODER PHENOLEN UNTER VERWENDUNG DES GENANNTEN KATALYSATORS

摘要

The herein-proposed catalyst for dehydrogenation oxygen-containing derivatives of the cyclohexane series having the following general formula where R1 is either hydrogen or alkyl C1-C4, R2 and R3 are radicals having either the same or different values -H, -OH, =O, provided that R2 and R3 are not hydrogen atoms both at a time, R1, R2, R3 being linked to different carbon atoms of the ring to form the corresponding cyclic ketones and/or phenols, comprises the following components (wt. %): nickel-15 to 55 tin-0.2 to 1.95 inert carrier-84.8 to 43.05, while the atomic ratio of nickel and tin lies within 15:1 and 410:1, respectively, and may contain additionally an alkali salt of a mineral acid in an amount of 0.01 to 1.0 wt. %.
