Elektrokemisk fremgangsmåde til fremstilling af alkalimetalalkoholater og anvendelse deraf til regenerering af katalysatoren ved methylformiatsyntesen

摘要

The invention relates to a process for the electrochemical synthesis of alkali metal alcoholates (alkoxides) and/or for the regeneration of the catalyst from methyl formate synthesis from alcoholic solutions of salts of alkali metals in an electrolysis apparatus with an ion-selective membrane. The electrolysis is carried out in the presence of a defined quantity of a potassium salt or sodium salt of a perfluoroalkanesulphonic acid accompanied by the use of non-oxidisable anode material and with a membrane based on a sulphonated styrene-divinylbenzene copolymer. The process enables an increase in the selectivity of the procedure and a continuous synthesis.
