Verfahren zur Herstellung von 1,2-Dichlorethan aus Ethylen und Chlorgas

摘要

In this manufacturing method,0 1,2,2- dichloroethanes acts on the condensation and cooling that will generate in a schlaufenreaktor in the case where verdampfungsk ü hlung katalysatorfreien br ü den ethylendichlorid are with retinue there are lewiss uren as catalyst in 105 and 225 ° of c ethylendichlorids about between the bars formed between 2 and 20 horizontal reaktionsdr ü cken quimolaren and boiling point by ethylene and chlorine,And liquid katalysatorhaltiges ethylendichlorid are deducted respectively. ;In order to evade the progress of chlorgaskompression and program, so that high monobutyltin trichloride product is formed and destillationsr ü ckst nden are largely suppressed, so that program be made to carry outA) in a cohesion and gekuhlten kreislaufstrom from ethylendichlorid gaseous chlorines are entirely used, purity is about 90 to 100 volumes. %,With(b)It initiates,Gained chlorination ethylendichlorid electric power reaktionsdruck,Then from abgezogenes katalysatorhaltiges ethylendichlorid to the c of reactor)In chlorination and cooling mono- ethylendichloridstromes of katalysatorfr of katalysatorhaltige ethylendichloridstrom,Then,Decline as final products ethylendichlorid from air-flow,hochgeheizt D),Then it is added to ethylene and abw rtsstrom teilstromes in the abw rtsstrom of next reactor)The ethylenhaupteinleit of contact reactor initiate ground 30 and 200 kilograms between a massengeschwindigkeit ungsmenge/second.
