Title (EN) METHOD FOR OBTAINING 1,2-DICHLORETHANE
(FR) PROCEDE DE PRODUCTION DE 1,2-DICHLORETHANE
Abstract: front page image
(EN)A method for obtaining 1,2-dichlorethane comprises the electrolysis of the 12-36 percent aqueous solution of hydrochloric acid at a temperature of 45-70 C with simultaneous supply of ethylene into the anode space. A metal of the iron group, or a compound including a metal of that group, or an alloy containing at least one of the metals of the iron group or any combination of the above substances is added to the aqueous solution of the hydrochloric acid before the electrolysis is started, so that the concentration of the ions of the metals of the iron group in the aqueous solution of the hydrochloric acid are not less than 0, 006 g-ions per litre of the said solution.
(FR)Un procede de production de 1,2-dichlorethane comprend l"electrolyse d"une solution aqueuse a 12-36% d"acide chlorlydrique a une temperature comprise entre 45 et 79 C avec alimentation simultanee d"ethylene dans l"espace de l"anode. Un metal du groupe du fer, ou un compose comprenant un metal de ce groupe, ou un alliage contenant au moins un des metaux du groupe du fer ou toute combinaison des substances precedentes est ajoutee a la solution aqueuse d"acide chlorlydrique avant de commencer l"electrolyse, de sorte que la concentration en ions de metaux du groupe du fer de la solution aqueuse d"acide chlorlydrique ne soit pas inferieure a 0,06g-ions par litre de solution.
