Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE PREPARACION DE AL - HIDROXI ACIDOS CALENTANDO SALES DE AMONIO DE AL HIDROXI ACIDOS DE FORMULA GENERAL (I); ELIMINANDO EL AMONIACO FORMADO Y AGUA; AÑADIENDO AGUA AL RESIDUO; Y CALENTANDO LA MEZCLA OBTENIDA; SIENDO R HIDROGENO, ALQUILO C 1 - C 6 , ALQUIL (C 1 - C 6 ), TIOALQUILO (C 1 - C 6 ), FENILO O SIMILARES. DICHO PROCESO NO ADOLECE DEL PROBLEMA DEL DESECHADO DE LOS SUBPRODUCTOS, COMO EL BISULFATO DE AMONIO, Y POSIBILITA LA PREPARACION DE UN AL - HIDROXI ACIDO LIBRE, A PARTIR DE UNA SAL DE AMONIO DEL MISMO, DE FORMA ECONOMICA Y CON UN ELEVADO RENDIMIENTO.
