実験手順

A mixture of 8.3 parts of 4-amino-3-nitrobenzaldehyde in 200 parts of methanol is hydrogenated at normal pressure and at room temperature with 5 parts of Raney-nickel catalyst. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated, yielding 8.5 parts of 3,4-diaminobenzenemethanol as an oily residue.

後処理
