The promoting effect of ethanol on the synthesis of N-(2-methylphenyl)hydroxylamine from o-nitrotoluene in Zn/H₂O/CO₂ system was observed. By adding appropriate amount of ethanol, the selectivity of N-(2-methylphenyl)hydroxylamine increased from 71% to 90% when the reduction was carried out at 25℃ under normal pressure of CO₂.
