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.
La présente invention concerne des procédés de fabrication de diphényloxydes sulfurés dans lesquels on fait réagir un diphényloxyde avec du soufre élémentaire en présence d'un catalyseur acide solide. Ce catalyseur acide solide peut être un zéolite ou une dose catalytique d'un composé Friedel-Crafts. Cette invention concerne également une composition renfermant de 40 à 80 % en poids de diphényloxyde, 15 % en poids maximum de diiphényloxyde thiol, de 5 à 45 % en poids de phénosythiine, et de 3 à 50 % en poids de bis(diphényloxyde) sulfure, de diphénylloxyde phénoxathiine sulfure et de bis(phénoxathiine) sulfure.
