Two paraffin carbonate materials, Jolliet wax from crude oil and hexatriacontone, were used in this study to test the effectiveness of different wax inhibitor candidates, including arachidyl alcohol, behenic acid, poly(ethylene vinyl acetate) and poly(1-octadecene maleic anhydride). It was found that both natural and manufactured paraffin wax could not be easily stabilized in the organic media by these chemicals. From the experimental result, it is proposed that effective paraffin inhibitors require a sufficiently long aliphatic chain structure to form strong van der Waals attractions to paraffin molecules to prevent or modify their crystallization. These long aliphatic chain of inhibitors may result in the instability of inhibitors. Polymeric molecules such as poly ethylene vinyl acetate) can slightly reduce the precipitation temperature of paraffin wax materials.
