Title (EN) PROCESS FOR PREPARING DICHLOROHYDRIN
(FR) PROCÉDÉ DE PRÉPARATION DE DICHLOROHYDRINE
Abstract:
(EN) The invention relates to a process wherein a stream comprising dichlorohydrin, water, and HCI is separated into a stream which is rich in dichlorohydrin and low in HCI and an aqueous HCI stream which is low in dichlorohydrin. The process involves the distillation of the mixture comprising dichlorohydrin, water, and HCI with an amount of water being added before and/or during the distillation such that the water concentration during the distillation is on the line D-E, or to the right thereof, in the phase diagram of Figure 1.
(FR) La présente invention a pour objet un procédé, un courant comprenant de la dichlorohydrine, de l'eau, et du HCl étant séparé en un courant qui est riche en dichlorohydrine et pauvre en HCl et un courant de HCl aqueux qui est pauvre en dichlorohydrine. Le procédé implique la distillation du mélange comprenant de la dichlorohydrine, de l'eau, et du HCl avec une quantité d'eau ajoutée avant et/ou pendant la distillation, de telle sorte que la concentration en eau pendant la distillation soit sur la ligne D-E, ou à sa droite, dans le diagramme de phase de la Figure 1.
