AceNaphthenol acetate

The acenaphthenol acetate contains small amounts of acenaphthene and acenaphthenone but is pure enough for the next step. 

Acenaphthenequinone, 24,1 Acenaphthenol-7, 21,1 Acenaphthenol acetate, 21,1 Acenaphthenone, 21, 3 /9-3-Acenaphthenylcarbonylpropi-... 

For example, oxidation of acenaphthene by red lead in acetic acid gives 7-acenaphthenol acetate, from which 7-acenaphthenol is obtained by saponification with methanolic sodium hydroxide. Phenols may be prepared indirectly from aromatic aldehydes by oxidation with peracetic acid followed by hydrolysis of the resulting aryl formate. "... 

B) Acenaphthenol.—The acetate obtained as above is dissolved in 275 cc. of methanol in a 2-1. round-bottomed flask, and a solution of 40 g. (1.2 equiv.) of sodium hydroxide in 400 cc. of water is added (Note 7). This mixture is refluxed for two hours (Note 7) and then cooled below 20°. The yellow crystalline acenaphthenol is collected on a filter and washed well with about...
