Abstract
Método para producir carbamida cristalina de alta pureza.#La invención se refiere a un método para producir carbamida cristalina de alta pureza. El método comprende la cristalización y el secado de carbamida, en el que una disolución acuosa de carbamida se precalienta a desde +30ºC hasta +130ºC, y después de eso la disolución se purifica mediante electrodiálisis a una tensión en el intervalo de 400 V 600 V. El resultado técnico es la producción de carbamida cristalina de alta pureza que puede usarse como aditivo en la industria alimentaria y como reactivo en análisis de laboratorio.
