    摘要: The present invention relates to methods for production of sulfurized diphenyloxides wherein a diphenyloxide is reacted with elemental sulfur in the presence of solid acid catalyst. The solid acid catalyst can be a zeolite or a catalytic amount of a Friedel-Crafts compound. The present invention further relates to a composition containing between about 40 and about 80 weight percent diphenyloxide; no more than about 15 weight percent diphenyloxide thiol; between about 5 and about 45 weight percent phenoxathiin; and between about 3 and about 50 weight percent total of bis(diphenyloxide) sulfide, diphenyloxide phenoxathiin sulfide, and bis(phenoxathiin) sulfide.
