Abstract: DONDE UNA PARTE DEL AGUA CONTENIDA EN LA SOLUCION ES AGUA LIMPIA (AGUA CORRIENTE, DE RIO, PURIFICADA O DESMINERALIZADA), Y LA OTRA PARTE ES AGUA RESIDUAL TRATADA (CLARIFICADA PARA ELIMINAR LOS SOLIDOS Y/O METALES PESADOS COMO EL ZINC) GENERADA DE UN PROCESO PARA LA EXTRACCION DE METALES NOBLES DE MINERALES QUE LOS CONTIENEN CON CIANURO; Y EL CIANURO METALICO ES UN CIANURO DE METAL ALCALINO O METAL ALCALINO TERREO, DE PREFERENCIA CIANURO DE Li, Na, K o Ca, EN UNA CANTIDAD ENTRE 0,001% Y 35% EN PESO EN BASE AL PESO TOTAL DE LA SOLUCION. EL pH DE LA SOLUCION OSCILA ENTRE 7 Y 13,5. EL PROCESO COMPRENDE: a) REACCION DE CIANURO DE HIDROGENO O GASES QUE LO CONTIENEN, CON UNA SOLUCION QUE CONTIENE AL MENOS UN HIDROXIDO METALICO Y/U OXIDO METALICO Y/U OXIDO MIXTO Y AGUA; b) DE CORRESPONDER, DILUCION CON AGUA DE LA SOLUCION OBTENIDA DE (a); SIENDO EL AGUA LA DESCRITA PARA LA SOLUCION. LOS METALES NOBLES SON ORO Y PLATA

Abstract: The invention relates to a process for separating close-boiling, homo- and heteroazeotropic mixtures by using ionic liquids. Due to the selectivity and unusual combination of properties of the ionic liquids the process is superior to conventional extractive rectification from the point of view of costs and energy.

Abstract: Production of hydrogen cyanide and water comprises contacting gaseous formamide with a catalyst at 350-800 deg C in a flow-type reactor with electric resistance heating. An Independent claim is also included for the apparatus for carrying out the above process, comprising either: (a) a flow reactor containing one or more catalyst-coated heating elements that can be heated by means of a voltage source; or (b) one or more flow tubes that can be heated by means of a voltage source and contain a bed of catalyst.
