ELECTRODIALYSIS IN A NONAQUEOUS MEDIUM - A CLEAN PROCESS FOR THE PRODUCTION OF ACETOACETIC ESTER

Alkoxide is used as an agent and consumed in condensation reactions, e .g., in the production of acetoacetic ester. Working in an alcoholic m edium and starting from a salt, it is possible to produce an alkoxide by means of electrodialysis. This principle was applied successfully f or the production of acetoacetic ester and the recovery of the alkoxid e in a single step. Such a process would offer self-sufficiency; the a lkoxide could be recovered, thus foregoing the use of mineral acids an d the consequent production of a salt as a waste. The merits can be se en in an economical as well as in an ecological context.
