    Abstract: Procedimiento para la obtención de isocianatos de ácido arilsulfónico mediante reacción de una arilsulfonamida con fosgeno, en el que se dispone en una zona de reacción la arilsulfonamida y una cantidad con eficacia catalítica de un isocianato de alquilo, formándose como intermedio una alquilarilsulfonilurea, y se añade con dosificación el fosgeno a la zona de reacción, caracterizado porque a) la reacción se lleva a cabo en presencia de una cantidad con eficacia catalítica de un ácido prótico, que presenta al menos un grupo hidroxi apto para la protólisis, o una sal del mismo, y/o b) la adición con dosificación de fosgeno se efectúa de modo que no se sobrepase una concentración de alquilarilsulfonilurea de 100 ppm en la zona de reacción durante el tiempo de adición con dosificación.
