Phenol to benzaldehyde
Web7. apr 2024 · Remember that the conversion of toluene to benzaldehyde by use of reagent is termed as Etard reaction. This reaction is used to produce benzaldehyde for many purposes. The reaction of benzaldehyde with hydrogen peroxide and sodium hydroxide is named as Dakin reaction. It is commonly used to prepare phenol. Webbenzaldehyde (C6H5CHO), the simplest representative of the aromatic aldehydes, occurring naturally as the glycoside amygdalin. Prepared synthetically, it is used chiefly in the manufacture of dyes, cinnamic acid, and other organic compounds, and to some extent in perfumes and flavouring agents. Benzaldehyde was first isolated in 1803, and in the …
