Abstract

Es conocido el aislamiento de MHA a partir de una mezcla de reaccion, que se obtiene por adicion de ácido prusico HCN) a aldehído metilmercaptopropionico (MMP) e hidrolisis de la ciahidrina del aldehído metilmercaptopropionico (MMP-CH) así obtenida con ácido sulfurico poniendo la mezcla de reaccion en contacto con un disolvente orgánico esencialmente no miscible con agua en un sistema de extraccion líquido/líquido, para formar una solucion de extraccion, que contiene el disolvente y MHA transformado de la mezcla de reaccion, obteniéndose el MHA como extracto a partir de esta solucion de extraccion por concentracion. El proceso más simple y economico posible de la invencion por lo que se refiere al tratamiento de los productos de reaccion, que facilita la preparacion de un producto altamente concentrado con un contenido extraordinariamente bajo de dímeros, oligomeros y subproductos, se caracteriza porque la concentracion se realiza de tal manera que el extracto remanente contiene menos de 4% en peso de agua, preferiblemente menos de 2% en peso de agua. Suplemento de piensos, y mezclas para la suplementacion de piesos, por ejemplo, con metionina o amonio-MHA.
