The color reaction of aromatic aldehyde with acenaphthene was investigated to clarify the mechanism of the coloration. When the colored solution of aldehyde with acenaphthene in concentrated sulfuric acid was treated with ice water, bis [1-(5-acenaphthenyl) benzyl] ether derivative was obtained, as a reaction product. It was assumed that the coloration might be ascribed to 1-(5-acenaphthenyl) benzyl cation derivative.
