Abstract
SE PRESENTAN METODO SEGUN LOS CUALES UN COMPUESTO DE N-C-N SE REGENERA A PARTIR DE UN PRODUCTO DE UNA REACCION DE DEPURACION DE AZUFRE, EN QUE DICHO COMPUESTO DE N-C-N SEPARA UN ATOMO DE AZUFRE DE UN COMPUESTO DE AZUFRE PARA FORMAR EL COMPUESTO DE N-C-N ORIGINAL. EL COMPUESTO DE N-C-N QUEDA REPRESENTADO POR LA FORMULA (I). EL PRODUCTO INCLUYE UN COMPUESTO HETERO QUE CONTIENE ATOMOS DE AZUFRE, CARBONO Y NITROGENO EN LA CADENA PRINCIPAL. EN UN ASPECTO DE LA INVENCION EL PRODUCTO SE MEZCLA CON (1) UN COMPUESTO DE NITROGENO REPRESENTADO POR LA FORMULA (II) Y (2) UN COMPUESTO ALCALINO SELECCIONADO DE COMPUESTOS DE METALES ALCALINOS, TIERRAS RARAS ALCALINAS Y METALES DE TRANSICION, PARA FORMAR UNA SOLUCION, LECHADA O DISPERSION. AL COMPUESTO HETERO SE LE HACE REACCIONAR CON EL COMPUESTO DE NITROGENO EN PRESENCIA DEL COMPUESTO ALCALINO, DE TAL MODO QUE UN ATOMO DE AZUFRE DEL COMPUESTO HETERO SEA SUSTITUIDO POR UN ATOMO DE NITROGENO DEL COMPUESTO DE NITROGENO. EN CASO NECESARIO SE AJUSTA EL PH DE LA SOLUCION A ENTRE 8 APROXIMADAMENTE Y 13 APROXIMADAMENTE PARA FACILITAR LA REACCION. EN ASPECTOS ALTERNATIVOS DE LA INVENCION, EL PRODUCTO INCLUYE TAMBIEN UN COMPLEJO DE AMINA. EL ATOMO DE NITROGENO QUE SUSTITUYE AL ATOMO DE AZUFRE DEL COMPUESTO HETERO SE PUEDE OBTENER BIEN DEL COMPUESTO DE NITROGENO O DEL COMPLEJO DE AMINA.
