Abstract
Se proporciona un método para refinar acesulfamo de potasio (Ace K), que incluye: adicionar peróxido de hidrógeno y carbón activado a una solución que contiene producto bruto de Ace K para obtener una mezcla, mantener la mezcla a una primera temperatura preestablecida durante un primer tiempo preestablecido, y filtrar la mezcla para obtener un licor madre de Ace K; llevar a cabo la concentración en el licor madre de Ace K a una concentración preestablecida para obtener una solución concentrada, dejar que la solución concentrada repose a una segunda temperatura preestablecida durante un segundo tiempo preestablecido para formar un núcleo de cristal de Ace K, y obtener una solución que contiene núcleo de cristal; llevar a cabo la congelación programada en la solución que contiene núcleo de cristal para obtener una solución con un gran número de cristales de Ace K; y llevar a cabo la centrifugación, lavado con agua, y secado en la solución con un gran número de cristales de Ace K para obtener un producto de cristal de Ace K. La presente divulgación tiene los siguientes efectos beneficiosos: al controlar el proceso de cristalización y la tecnología, se obtiene un producto de cristalización de alta calidad y alta pureza con un menor contenido de impurezas, y se mejoran significativamente la pureza y la calidad del cristal de Ace K; además, el método para refinar Ace K tiene un proceso simple, condiciones suaves y controlables, y bajos requisitos para el equipo y habilidades de personal, que es extremadamente adecuado para la producción industrial a gran escala.
