- 1. A method for preparing a complex of a phenolic compound selected from the group consisting of phenol, resorcinol, dihydroydiphenyl sulfone, B-naphthol, p-cresol, p-phenylphenol, m-methoxyphenol, 3,5-xylenol, o-cresol, o-chlorophenol, o-phenylphenol and 2,4-dichlorophenol comprising: mixing the phenolic compound and hexamethylenetetramine and a suitable solvent in which mixture the amount of solvent is insufficient to dissolve all of the hexamethylenetetramine and all of the phenolic compound simultaneously, and drying the mixture at a temperature less than that which would cause decomposition of the complex.
- 2. The method of claim 1 wherein the amount of solvent is less than about 30% by weight of the mixture.
