実験手順

201 parts of α-naphthyl acetate and 45 parts of water are introduced into a stirred autoclave, the mixture is heated to 200° C., whilst stirring, resulting in an autogenous pressure of 15 bars. After 75 minutes at 200° C., the emulsion formed changes to a clear solution. After 6 hours at 200° C., the mixture is distilled. 134.5 parts of α-naphthol (86.5% of theory) of boiling point 130° C./13 mbar, 3 parts of naphthyl acetate and 9.5 parts of residue are obtained.
