Yield:83-55-6 95%
Reaction Conditions:
with hydrogen;5%-palladium/activated carbon in isopropyl alcohol at 50; under 6000.6 Torr; for 2 h;
Steps:
7 EXAMPLE 7 Reduction of 5-nitro-1-naphthol
In an autoclave was placed 1.9 g of 5-nitro-1-naphthol, 0.02 g of 5% Pd/C (containing 50% by weight of water), and 50 g of isopropanol, and the hydrogen pressure was set at 0.8 MPa. The reaction was carried out at 50 C. for 2 hours. After the reaction mixture was cooled, the catalyst was filtered off, and the reaction mass thus obtained was analyzed by gas chromatography. As a result, the content of 5-amino-1-naphthol produced was 1.5 g (yield 95%).
