Abstract
La divulgación revela un sistema de extracción y un procedimiento de extracción para separar magnesio y extraer litio y boro a partir de salmuera que contiene magnesio con un disolvente complejo de amida secundaria / alcohol alquílico, así como aplicaciones de los mismos. El sistema de extracción contiene amidas secundarias y alcoholes alquílicos que se utilizan por separado como extractantes para extraer litio y boro y consisten en un compuesto único o una mezcla de dos o más compuestos, y el número total de átomos de carbono en sus moléculas es de 12 a 18 y de 8 a 20 respectivamente; el sistema de extracción tiene un punto de congelación menor que 0ºC. Con una relación en volumen de una fase orgánica y una fase en salmuera que es de 1 a 10:1, a una densidad de salmuera de 1,25 a 1,38 g/cm³, a un valor de pH de salmuera de 0 a 7 y a una temperatura de 0 a 50ºC, se lleva a cabo una extracción en contracorriente de una o múltiples etapas y una destilación para obtener una fase acuosa con una relación de magnesio-litio baja, que se somete a concentración, eliminación de impurezas y preparación para conseguir cloruro de litio, carbonato de litio, hidróxido de litio y ácido bórico respectivamente. En la divulgación, la amida secundaria tiene una estructura molecular simple, el disolvente complejo mejorado con alcoholes alquílicos puede extraer litio y boro simultáneamente; la tasa de extracción de múltiples etapas es alta, se utiliza agua para la destilación, lo que reduce en gran medida el consumo de ácido y base; el proceso de extracción y separación se acorta, y la pérdida de solución del sistema de extracción es pequeña, por lo que tiene valores de aplicación industrial.
