Abstract

Electrolysis cell esp. for the electrolysis of NaCl soln., with a casing, an anode, a cathode and a diaphragm which is practically impermeable to liquids and gas and separates the anode and the cathode is characterised by the diaphragm consisting of a hydrolysed copolymer of tetrafluoroethylene and sulphonated perfluorovinyl ether of formula FSO2CF2CF2OCF(CF3)CF2OCF = CF2 with a mol. wt. of 900-1600, pref. 1100-1400. The diaphragm prevents undesirable molecular and ionic migration, but allows conduction of electrical current by movement of desirable ions.

Description

(54) СПОСОБ ПОЛУЧЕНИЯ ХЛОРА И КАУСТИЧЕСКОЙ СОДЫ(54) METHOD FOR PRODUCING CHLORINE AND CAUSTIC SODA

окиси натри  в катодной камере по щерживает с  в интервале от 24 до 337с по весу.Sodium oxide in the cathode chamber is capped with between 24 and 337s by weight.

Данна  мембрана обеспечивает получение продукта высокой чистоты - водорода, извлекаемого из катодной камеры, также при электролизе сол ной кислоты.This membrane provides a high-purity product — hydrogen extracted from the cathode chamber — also during the electrolysis of hydrochloric acid.
