Effect of the Solvent Composition on the Content of the Crystalline Phase and Melting Temperature of Paraffin Waxes.

The results of a study of melting the commercial waxes in the composition of asphaltene-resin-paraffin deposits and for comparison of petroleum waxes in multicomponent solvents of various nature are presented. It was found that with an increase in the amount of the aliphatic component in the solvent, the content of the crystalline phase in paraffin wax rises. Patterns in the variation of paraffin melting temperatures depending on the content of the crystalline phase were revealed. Recommendations for choosing an effective solvent for removing deposits under conditions of permafrost influence are suggested. [ABSTRACT FROM AUTHOR]
