Abstract

Améliorations relatives à la production et à la stabilisation du perchlorométhylmercaptan. Pour améliorer le rendement en perchlorométhylmercaptan. on incorpore au mélange réactionnel des composés carbonylé difonctionnels, des phosphates, des phosphites, des phospho nates ou des phosphonites en des quantités supprimant la formation des sous-produits indésirables tels que le tétrachlorure de carbone et le monochlorure de soufre et on obtient simultanément une amélioration du rendement en perchlorométhylmercaptan ; l'incorporation d'une quantité appropriée d'un phosphate améliore la stabilité du perchloromethylmercaptan brut. L'invention s'applique en particulier à l'obtention industrielle de perchlorométylmercaptan dépourvu de sous-produits indésirables.Improvements in the production and stabilization of perchloromethylmercaptan. To improve the yield of perchloromethylmercaptan. difunctional carbonyl compounds, phosphates, phosphites, phosphonates or phosphonites are incorporated into the reaction mixture in amounts which suppress the formation of undesirable by-products such as carbon tetrachloride and sulfur monochloride and simultaneously an improvement is obtained the yield of perchloromethylmercaptan; the incorporation of an appropriate amount of a phosphate improves the stability of the crude perchloromethylmercaptan. The invention applies in particular to the industrial production of perchlorometylmercaptan devoid of undesirable by-products.
