Abstract

Se describe un proceso eficiente para la preparación continua de tiosulfato de calcio (CaS2O3) a partir de sulfuro de calcio. El proceso implica oxidar un intermedio de polisulfuro de calcio en una serie de reactores, tales como una serie de reactores de tanques con agitación continua, para producir tiosulfato de calcio como un líquido transparente a alta concentración con subproductos mínimos. En el primer reactor, se oxida parcialmente polisulfuro de calcio, y se transfiere la solución resultante a un segundo reactor y se oxida adicionalmente. La solución producida en el segundo reactor se transfiere a un tercer reactor y luego sustancialmente se oxida por completo para formar una solución de tiosulfato de calcio sustancialmente oxidada por completo.An efficient process for the continuous preparation of calcium thiosulfate (CaS2O3) from calcium sulphide is described. The process involves oxidizing a calcium polysulphide intermediate in a series of reactors, such as a series of tank reactors with continuous agitation, to produce calcium thiosulfate as a clear liquid at high concentration with minimal by-products. In the first reactor, calcium polysulfide is partially oxidized, and the resulting solution is transferred to a second reactor and further oxidized. The solution produced in the second reactor is transferred to a third reactor and then substantially oxidized completely to form a completely oxidized calcium thiosulfate solution.
