Dearomatization of liquid paraffin with dimethylformamide

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Summary

  1. 1.

    Dimethylformamide can be used as a selective solvent for the aromatic hydrocarbons contained in the liquid paraffins from the urea dewaxing process.

  2. 2.

    At a dimethylformamide to feedstock ratio of 3.5 and an extraction temperature of 40–50°C, one can obtain paraffin with an aromatic hydrocarbon content of 0.45%.

    At a triethylene glycol to feedstock ratio of 15 and an extraction temperature of 120–130°C, one can obtain paraffin with an aromatic hydrocarbon content of 0.5%.
