Resorcinol and pyrogallol have been condensed with stearic, palmitic and lauric acids to obtain the dihydroxy and trihydroxy ketones. Chromones have been prepared from them, and it is observed that the resulting γ-pyrones gave only the orignial ketones on alkaline hydrolysis, and not a trace of theo-hydroxy-carboxylic acids. As most of these ketones were prepared for the first time, their bromination, nitration and reduction were studied. The last reaction gave resorcinols and pyrogallols containing octadecyl, hexadecyl and dodecyl-groups in the 4-position.
