Process for producing p-hydroxybenzaldehyde |
| abstract |
A process for producing p-hydroxybenzaldehyde through p-aminobenzaldehyde from p-nitrotoluene, comprising reacting p-nitrotoluene with sodium polysulphide in an alcohol-alkali aqueous solution mixed solvent in the presence or absence of an aprotic polar compound to produce p-aminobenzaldehyde, diazotizing the p-aminobenzaldehyde and then hydrolyzing the diazotized p-aminobenzaldehyde to produce p-hydroxybenzaldehyde. |
