          Abstract

          RESUMEN En el presente trabajo se evaluó a escala de laboratorio, en condiciones de seguridad, un método para la destrucción de sodio metálico caduco. Para ello se estudió, en dos etapas, su reacción con etanol. Se investigó experimentalmente la variación de la temperatura del sistema de reacción en función de la velocidad de dosificación del sodio, la relación de la masa de etanol técnico-sodio en dependencia del por ciento en peso del etanol empleado, la cantidad de agua en la segunda etapa, y la velocidad de agitación. A partir de este estudio, se precisan los parámetros del método propuesto, que permiten darle tratamiento a este reactivo en obsolescencia. Finalmente, se realizó una caracterización elemental del residuo formado, proponiéndose varias alternativas para su manejo, destacando que más del 98 % del etanol utilizado en la primera etapa, se recupera por destilación, garantizando su reúso.

          ABSTRACT In the present work was to asses, on a laboratory scale, a method for the destruction of expired metallic sodium under safe conditions. For this, its reaction with ethanol was studied, which occurs in two stages. The variation of the temperature of the reaction system as a function of the sodium dosing rate, the mass ratio of technical ethanol/sodium depending on the weight percent of the ethanol used, the need for water in the second stage, and the stirring speed were experimentally investigated. From these tests, the parameters were obtained, to safely carry out the destruction of this metal. Finally, an elemental characterization of the waste formed was carried out, proposing several alternatives for its management, highlighting that more than 98 % of the ethanol used in the first stage is recovered by distillation, guaranteeing its reuse.
