Abstract
PROCEDIMIENTO DE PREPARACION DE 3-TRIFLUOROMETIL-4K-HIDROXI-A-ETIL-BENZOL. CONSISTE EN REDUCIR UN COMPUESTO DE FORMULA (I) DONDE R1 ES H; Y R2 ES 3-TRIFLUOROMETILO, O R1 ES 2-METILO Y R2 ES 5-METILO. LA SEPARACION POR REDUCCION DEL GRUPO BENCILO SE LLEVA A CABO MEDIANTE HIDROGENACION CATALITICA EMPLEANDOSE COMO CATALIZADORES METALES, COMO RUTENIO, PALADIO, NIQUEL, HIERRO, COBRE Y OTROS, Y LOS OXIDOS Y SULFUROS DE ESTOS METALES; DONDE LOS CATALIZADORES PUEDEN PREPARARSE REDUCIENDO SUS OXIDOS ESTABLES CON HIDROGENO, DIRECTAMENTE EN EL RECIPIENTE DE REACCION. LA HIDROGENACION SE LLEVA A CABO A PRESION ATMOSFERICA SUPERIOR A 506,6 KPA Y A UNA TEMPERATURA ENTRE 20JC Y LA DEL PUNTO DE EBULLICION DE LA MEZCLA DE REACCION; REALIZANDOSE LA REDUCCION A TEMPERATURA AMBIENTE Y A PRESION ATMOSFERICA HASTA EL CESE DE LA ABSORCION DE HIDROGENO. TIENE APLICACIONES FARMACEUTICAS.
