Abstract
Sposób otrzymywania epichlorohydryny polegajacy na odchlorowodorowaniu 1,3-dichloro-2-propanolu roztworem mleka wapiennego, otrzymanego podczas chlorowodorowania glicerolu gazowym chlorowodorem charakteryzuje sie tym, ze miesza sie i wstepnie odchlorowodorowuje 1,3-dichloro-2-propanol w prereaktorze (5) w sposób ciagly, nastepnie mieszanine reakcyjna kieruje sie do kolumny reakcyjno-odpedowej (6), z której splywa do wyparki (12), gdzie w strumieniu pary wodnej o temperaturze 70 do 120°C oddestylowuje sie epichlorohydryne i pozostale zwiazki organiczne lotne, a sciek odprowadza sie na zewnatrz. Odchlorowodorowanie w prereaktorze prowadzi sie w temperaturze 40 do 70°C, pod cisnieniem 40 do 80 kPa, w czasie od 1 sekundy do 60 minut. Odchlorowodorowanie w kolumnie reakcyjno-odpedowej (6) prowadzi sie w temperaturze 60 do 80°C, pod cisnieniem 40 do 80 kPa, w czasie 1 do 20 sekund. Przedmiotem wynalazku jest równiez uklad do otrzymywania epichlorohydryny zawierajacy reaktor, wyparke, zbiorniki, pompy, wytwornice pary wodnej. Charakteryzuje sie on tym, ze ma prereaktor (5) usytuowany nad kolumna reakcyjno-odpedowa (6) polaczona od dolu z wyparka (12).The method of obtaining epichlorohydrin based on dehydrochlorination of 1,3-dichloro-2-propanol with a solution of milk of lime, obtained during the chlorination of glycerol with gaseous hydrogen chloride, is characterized by mixing and pre-dehydrochlorination of 1,3-dichloro-2-propanol in the pre-reactor (5) in continuously, then the reaction mixture is directed to the reaction-stripper column (6), from which it flows to the evaporator (12), where epichlorohydrin and other volatile organic compounds are distilled off in a stream of steam at a temperature of 70 to 120 ° C, and the effluent is discharged outside. The dehydrochlorination in the pre-reactor is carried out at a temperature of 40 to 70 ° C, under a pressure of 40 to 80 kPa, for a time ranging from 1 second to 60 minutes. The dehydrochlorination in the reaction stripper (6) is carried out at a temperature of 60 to 80 ° C and a pressure of 40 to 80 kPa for 1 to 20 seconds. The subject of the invention is also a system for the preparation of epichlorohydrin, including a reactor, evaporator, tanks, pumps, steam generators. It is characterized by the fact that it has a pre-reactor (5) situated above the reaction-stripper (6) connected to the bottom of the evaporator (12).
