Dehydrogenation catalyst in aminoalcohols or aminocarboxylic acids (derivatives) in ethylene glycol oxycarboxylic acids, method for its production and use.

摘要

CATALYST FOR dehydrogenation of aminoalcohols TO GIVE aminocarboxylic acids, OR (DERIVATIVES) ETHYLENE TO GIVE ACIDS oxycarboxylic CONTAINING ZIRCONIUM, copper and optionally other metal, wherein the said metals as hydroxides, washed, dried, calcined and reduced, and obtained from a solution aQUEOUS zirconium salt precipitates a base of zirconium hydroxide UNTIL YOU GET A pH of 4 to 10, the suspension of zirconium hydroxide is added to the aqueous solution of a copper salt and optionally another sa By adding another base copper hydroxide and optionally the metal hydroxide is in the other salt precipitates, UNTIL GETTING A pH of 8 to 14; FILTERING THE OBTAINED SUSPENSION, washed, dried and calcined from 450 to 600 C for 2 to 4 hours, and finally REDUCES 200 to 250 C in a hydrogen stream for 2 to 4 hours.
