Study on Over-Based Sulfurized Colcium Phenate Homologs (Part 3):Analytical Treatment of Characteristics of Mixed Homologs in Oil-Diluent

Abstract

A study was made on the estimating methods of the characteristics of over-based sulfurized calcium phenates containing about 150 to 1,000% of the theoretical amount of calcium which was prepared from p-octylphenol, calcium oxide, elemental su fur, ethylene glycol, carbon dioxide, lauryl alcohol and oil as starting materials. From the theory and the experimental values, some analytical expressions for alkalinity value, the specific gravity or the viscosity of the phenate and its more dilution, and for the specific gravity of the micell could be derived semi-empirically.
