Abstract
Se describe un método discontinuo o semi-continuo eficiente de producción de tiosulfato de calcio (CaS₂O₃), que contiene subproductos, con una alta concentración relativa a partir de polisulfuro de cal, azufre o calcio, y dióxido de azufre en elevadas condiciones de temperatura de reacción. El producto es una emulsión de tiosulfato de calcio líquido y subproductos sólidos. Bajo las condiciones de la técnica, incluyendo las relaciones en moles de cal a azufre, la temperatura del proceso de la reacción y las condiciones de reacción del dióxido de azufre, incluyendo velocidad y duración, los subproductos se reducen a alrededor de 2% en peso.
