Abstract

NUEVOS CATALIZADORES A BASE DE ORTOFOSFATO DE MAGNESIO, PROCEDIMIENTO PARA SU PREPARACION Y APLICACIONES. LOS CATALIZADORES RESPONDEN A LA FORMULA XMMGN (PO4)P EN LA QUE X ES UN CATION METALICO ALCALINO SELECCIONADO ENTRE SODIO, LITIO Y POTASIO; Y M = 0 O 1, N = 1 O 3 Y P = 1 O 2 CON CIERTAS CONDICIONES . EL PROCEDIMIENTO COMPRENDE: (A) REACCION DE CLORURO DE MAGNESIO CON HIDROGENOFOSFATO DE SODIO A PH 9 Y TEMPERATURA AMBIENTE; (B) ADICION AL MEDIO DE REACCION DE (A) DE UN CARBONATO DE METAL ALCALINO CALENTANDO A 60-80C DURANTE UNAS 5 HORAS; Y (C) CALCINACION DEL SOLIDO OBTENIDO PARA PRODUCIR COMPUESTOS DE FORMULA XMGPO4 EN QUE X=NA, LI, K. SI SE SUPRIME LA ETAPA (B) DEL PROCEDIMIENTO SE OBTIENE MG3 (PO4)2. Y H2O EN QUE Y=22,8 O 5. ESTOS PRODUCTOS SON UTILES COMO CATALIZADORES EN PROCESOS DE DESHIDROGENACION Y DESHIDRATACION DE ALCOHOLES, DE CONDENSACION ALDOLICA Y DE TRANSFERENCIA DE HIDROGENO.NEW CATALYSTS BASED ON MAGNESIUM ORTHOPHOSPHATE, PROCEDURE FOR ITS PREPARATION AND APPLICATIONS. THE CATALYSTS RESPOND TO THE FORMULA XMMGN (PO4) P IN WHICH X IS AN ALKALINE METALLIC CATION SELECTED BETWEEN SODIUM, LITHIUM AND POTASSIUM; Y M = 0 O 1, N = 1 O 3 Y P = 1 O 2 WITH CERTAIN CONDITIONS. THE PROCEDURE INCLUDES: (A) REACTION OF MAGNESIUM CHLORIDE WITH SODIUM HYDROGEN PHOSPHATE AT PH 9 AND ROOM TEMPERATURE; (B) ADDITION TO THE REACTION MEDIA OF (A) OF AN ALKALINE METAL CARBONATE HEATING TO 60-80C FOR ABOUT 5 HOURS; AND (C) CALCINATION OF THE SOLID OBTAINED TO PRODUCE COMPOUNDS OF FORMULA XMGPO4 IN WHICH X = NA, LI, K. IF STAGE (B) OF THE PROCEDURE IS REMOVED, OBTAIN MG3 (PO4) 2. AND H2O IN WHICH Y = 22.8 OR 5. THESE PRODUCTS ARE USEFUL AS CATALYSTS IN DEHYDROGENATION AND DEHYDRATION PROCESSES OF ALCOHOLS, ALDOLIC CONDENSATION AND HYDROGEN TRANSFER.
