ABSTRACT:
Manufacture a novel bis(formylphenyl)alkane according to General Formula (1), as well as a novel polynuclear phenol derived therefrom, by causing a bis(hydroxymethyl-hydroxyphenyl)alkane to react with hexamethylene tetramine in the presence of an acid and hydrolyzing the reaction product, and then using the obtained bis(hydroxy-formylphenyl)alkane as a direct material and causing this material to react with halogenated alkoxycarbonyl hydrocarbon in the presence of a base.
