Title (EN) METHOD FOR AVOIDING THE GENERATION OF BY-PRODUCTS DURING THE PRODUCTION OF HALOALKANE COMPOUNDS
(FR) PROCÉDÉ PERMETTANT D'ÉVITER LA PRODUCTION DE SOUS-PRODUITS PENDANT LA PRODUCTION DE COMPOSÉS ALCANES HALOGÉNÉS
Abstract:
(EN) Disclosed is a process for the manufacture of haloalkane compounds, and more particularly, to an improved process for the manufacture of the compound 1,1,1,3,3-pentachloropropane (HCC-240fa), which mitigates the formation of by-products. The present invention is also useful in the manufacture of other haloalkane compounds such as HCC-250 and HCC-360. One embodiment of the process comprises a method and system for avoiding the formation of polyvinyl chloride during the production of HCC-240fa from CCl4, in which vinyl chloride (VCM) is fed into a reactor as a vapor instead of as a liquid, using a diffusing device to further increase the contact surface between VCM vapor and CCl4.
(FR) L'invention porte sur un procédé pour la fabrication de composés alcanes halogénés et, plus particulièrement, sur un procédé perfectionné pour la fabrication du composé 1,1,1,3,3-pentachloropropane (HCC-240fa), qui atténue la formation de sous-produits. La présente invention est également utile dans la fabrication d'autres composés alcanes halogénés tels que HCC-250 et HCC-360. Un mode de réalisation du procédé comprend un procédé et un système permettant d'éviter la formation de poly(chlorure de vinyle) pendant la production de HCC-240fa à partir de CCl4, du chlorure de vinyle (CVM) étant introduit dans un réacteur sous forme de vapeur au lieu d'un liquide, à l'aide d'un dispositif diffuseur pour augmenter encore la surface de contact entre la vapeur de CVM et le CCl4.
