Abstract
SE PROPONE UN PROCEDIMIENTO MEJORADO PARA LA PREPARACION DE {AL},{BE} UP,3}R{SUP,2}NC(R{SUP,1}) = C(NR{SUP,2}R{SUP,3})CN, EN DONDE R{SUP,1} CORRESPONDE A HIDROGENO, RADICALES ALIFATICOS CON 1 A 30 ATOMOS DE CARBONO, RADICALES CICLOALIFATICOS CON 3 A 8 MIEMBROS DE ANILLO O A RADICALES AROMATICOS, HETEROAROMATICOS O ARALIFATICOS CON 7 A 12 ATOMOS DE CARBONO, PUDIENDO SER ESTOS RADICALES TAMBIEN SUSTITUIDOS; R{SUP,2} Y R{SUP,3} SON IGUALES O DIFERENTES Y SIGNIFICAN HIDROGENO O UN RADICAL ALIFATICO CON 1 A 15 ATOMOS DE CARBONO, UN RADICAL CICLOALIFATICO CON 3 A 8 MIEMBROS DE ANILLO O UN RADICAL AROMATICO, HETEROCICLICO O ARALIFATICO CON 7 A 12 ATOMOS DE CARBONO Y PUDIENDO UNIRSE TAMBIEN LOS RADICALES R{SUP,2} Y R{SUP,3} CONJUNTAMENTE A UN ANILLO DE 5 PROCEDIMIENTO, EL COMPONENTE A) ES TRANSFORMADO EN EL ORDEN DESEADO CON LOS COMPONENTES B), C) Y D). A) ES UN COMPUESTO {AL} UP,1} TIENE EL SIGNIFICADO ARRIBA MENCIONADO O ES UN DERIVADO REACTIVO DE ESTE COMPUESTO DE CARBONILO; B) ES UNA SAL DE ACIDO SULFUROSO, DIOXIDO DE AZUFRE O UN REACTIVO QUE SUMINISTRA DIOXIDO DE AZUFRE; C) ES UNA AMINA DE FORMULA GENERAL HNR{SUP,2}R{SUP,3}, O UNA DIAMINA ALIFATICA DE FORMULA GENERAL R{SUP,3}HN -(CH{SUB,2}){SUB,N} LENO PUEDE PORTAR TAMBIEN UN SUSTITUYENTE R{SUP,1}, TENIENDO R{SUP,1} Y R{SUP,3} EL SIGNIFICADO ARRIBA MENCIONADO Y SIENDO N LOS NUMEROS 2 O 3, O SON DERIVADOS QUE SON CONVERTIDOS EN AMINA O DIAMINA EN CONDICIONES DE REACCION; D) ES UN ACIDO CIANHIDRICO LIQUIDO O GASEOSO O UN REACTIVO QUE SUMINISTRA ACIDO CIANHIDRICO. LA TRANSFORMACION REFERIDA A UN MOL DE COMPONENTE A, ES REALIZADA CON AL MENOS 3,5 COMPUESTOS ALCALINOS EQUIVALENTES. LA MAYOR PARTE DE LOS COMPUESTOS ALCALINOS ESTA FORMADA POR COMPUESTOS DE POTASIO, AÑADIENDOSE AL MENOS UN EQUIVALENTE ALCALINO COMO LEJIA ALCALINA LIBRE, SIEMPRE QUE LA PROPORCION DE EQUIVALENTES DE POTASIO SEA LO SUFICIENTEMENTE ELEVADA COMO PARA QUE AL FINAL DE LA REACCION TODAS LAS SALES INORGANICAS PERMANEZCAN EN LA SOLUCION PRACTICAMENTE ENTERAS.
