All waxes and the like are alkylated to benzene using a Friedel-Crauch type catalyst. A general method for synthesizing alkaline earth metal phenolates is to synthesize phenol or alkylphenol, elemental sulfur, or alkaline earth metal oxides, products, or hydroxides in alcohols such as methanol, butanol, or ethylene glycol sodium as a solvent from room temperature to approx. There is a method of reacting at 250°C, etc. Examples of alkaline earth metals in the present invention include magnesium, calcium, and barium.
