Description
| - 4-methoxybenzaldehyd je cenná látka používaná při výrobě detergentů, parfémů, atraktantů a léčiv. Výrábí se selektivní elektrochemickou methoxylací 4-methylnisolu. Uvedený proces patří ke klíčovým technologiím BASF. Relativně novou a pro elektrochemii zajímavou skupinu látek představují tzv. iontové kapaliny. Jsou to nízkoteplotní taveniny solí, řada z nich je kapalná již pži pokojové teplotě. V této práci bylo studováno možné použití iontových kapalin při výrobě 4-methoxybenzaldehydu. Kinetika, reakční mechanismus a selektivita reakce byly studovány u dvou systémů: Triethylsulfonium bis(trifluoromethylsulfonyl)imid and N,N-Butylmethylpyrrolidinium bis(trifluoromethylsulfonyl)imid. Naměřené lineární voltamogramy psoloužily k určení kinetiky elektrodové reakce. Selektivita reakce pro požadovaný product byla určena z galvanostatických elektrolýz. (cs)
- 4-methoxybenzaldehyde (4-MBA) is a valuable compound used in detergents, perfumes, insect attractants and in synthesis of drugs. It is produced by selective electrochemical methoxylation from 4 methylanisole (4 MA) through an intermediate product, 4 methoxybenzylmethyl ether. This well optimized process is one of core technologies for BASF. Reaction is performed continuously in capillary gap cell with low conversion in one though-put and recycle of the electrolyte. In consequence, electrolyte mixture has to be used in recycle mode what increases separation cost. This problem can be solved utilizing improved electrochemical cell design and electrochemical system providing higher process kinetics and selectivity. One of the most important aspects is a selection of a proper supporting electrolyte. This requires understanding of a reaction mechanism and kinetics. Wide group of salts has been studied until now. So far KF has been quoted as the best option for mentioned process. Superiority of KF was also
