Abstract

Procedimiento para la obtención de ácidos antraquinonsulfónicos, prácticamente libres de mercurio, caracterizado porque se sulfona antraquinona con ácido sulfúrico que contiene SO3 en presencia de catalizadores conteniendo mercurio, a temperatura elevada, la mezcla de sulfonación se trata a continuación, en cado dado después de diluir con agua, con azufre o un compuesto inorgánico u orgánico del azufre bivalente y a continuación , en caso dado después de diluir con agua, se separan los compuestos de mercurio presentes en forma insoluble, y a continuación, los ácidos antraquinonsulfónicos se aislan en forma conocida
