Abstract

Sposób oczyszczania epichlorohydryny, z wykorzystaniem procesu destylacji, według wynalazku charakteryzuje się tym, że epichlorohydrynę poddaje się destylacji na pierwszej kolumnie rektyfikacyjnej (1) otrzymując destylat, który wykrapla się w deflegmatorze (2) i oddziela od fazy parowej w rozdzielaczu (3). Skropliny zawraca się jako orosienie kolumny rektyfikacyjnej (1), a nieskroplony destylat poddaje się rozdzielaniu na drugiej kolumnie rektyfikacyjnej (4), zaś niedogon odbiera się z dołu pierwszej kolumny rektyfikacyjnej (1). Destylat z drugiej kolumny rektyfikacyjnej (4) skrapla się w chłodnicy (5), rozdziela w rozdzielaczu (6) na fazę organiczną oraz wodną, przy czym warstwę organiczną recyrkuluje się jako orosienie drugiej kolumny rektyfikacyjnej (4), a frakcję wodną wykorzystuje się do sporządzania roztworu wodorotlenku wapnia, zaś na jednej z dolnych półek powyżej wyparki (10) za pośrednictwem skraplacza (8) odbiera się najwyższej czystości epichlorohydrynę. Niedogon z drugiej kolumny rektyfikacyjnej (4) recyrkuluje się do pierwszej kolumny rektyfikacyjnej (1).The process for purifying epichlorohydrin using a distillation process according to the invention is characterized in that epichlorohydrin is distilled on the first rectification column (1) to obtain a distillate which condenses in the deflector (2) and separates from the vapor phase in the separator (3). The condensate is recycled as a reflux of the rectification column (1), and the non-condensed distillate is separated on the second rectification column (4), while the low-temperature condensate is collected from the bottom of the first rectification column (1). The distillate from the second rectification column (4) is condensed in a condenser (5), separated in a separating funnel (6) into an organic and aqueous phase, the organic layer being recirculated as reflux of the second rectification column (4) and the aqueous fraction is used to prepare calcium hydroxide solution, while on one of the lower shelves above the evaporator (10) the highest purity epichlorohydrin is collected via a condenser (8). The insufficiency from the second rectification column (4) is recirculated to the first rectification column (1).
