  • in preparing dyes, plasticizers, and insecticides;
  • as a proton-donor solvent for coal extraction;
  • as heat transfer fluid at 210-310°C;
  • as raw materials for functional polymers;
  • as component of stove and jet fuels;
  • as an intermediate in pharmaceuticals syntheses;
  • for ore flotation;
