Abstract

It has been know since 1930 that a compound, m.p. 215° c., can be isolated from a p‐cresol‐formaldehyde resin made under acid conditions. The accepted structure of this compound was that of a linear molecule of three benzene rings linked by two methylene bridges. It was later suggested that the compound had a cyclic four‐ring structure, but evidence is now presented in support of the earlier trinuclear formulation. A new three‐ring compound, containing two chlorine atoms in place of two methyl groups, is also described.
