| Abstract: | This paper reported that determinating content of benzaldehyde in mixed electrolyte during electrolysing toluene to producing benzaldehyde by producing hydrazone analysis method. Influence of precipitating agent, acidity (acid content), composition in mixed electrolyte to analysis results was researched. The experimental results showed that this analytical approach have properties of stable date, nice reappearance, operate easily, high precision and degree of accuracy. It is a practical analysis method for determinating content of benzaldehyde during electrolysis. |
