METHODS FOR THE PRODUCTION OF SULFURIZED DIPHENYLOXIDES AND COMPOSITIONS MADE THEREFROM

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 40 and 80 weight percent diphenyloxide; no more than 15 weight percent diphenyloxide thiol; between 5 and 45 weight percent phenoxathiin; and between 3 and 50 weight percent total of bis(diphenyloxide) sulfide, diphenyloxide phenoxathiin sulfide, and bis(phenoxathiin) sulfide.
