Název v původním jazyce

The role of supporting electrolyte anion in the electrochemical methoxylation of 4-methylanisole

Popis výsledku v původním jazyce

Ring substituted aromatic aldehydes are important compounds with high added value. 4 Methoxybenzaldehyde is an example of such compounds. A classical way of 4 Methoxybenzaldehyde production is based on anodic methoxylation of 4 Methylanisole (4 MA) and subsequent acidic hydrolysis of 4-Methoxybenzaldehyde dimethylacetal separated from worked electrolyte. Intermediate product in the process is 4 Methoxybenzylmethyl ether (4 MBME). In the current contribution the influence of supporting electrolyte anionon kinetics and mechanism of the methoxylation reaction together with theirs impact on the reaction selectivity is discussed. Methanol electrolytes containing three different supporting electrolyte anions (F-, ClO4-, bis(trifluoromethansulfonate)imide) were studied. Classical electrochemical techniques such as linear voltammetry on stationary and rotating disc electrode were utilized in uncovering of reaction kinetics and mechanism. Gas chromatography with Flame Ionization Detector enabl
