Abstract

Various solvents have been used for extracting vegetable oils such as soybean oil. Certain petroleum fractions are widely used commercially. They have the advantage of low cost, but the disadvantage of being highly flammable and their vapors being explosive in a wide range of mixture with air. Certain of the chlorinated hydrocarbons are excellent solvents but have had only limited use because of high cost and lack of suitable processing methods and equipment. Process and equipment for the use of trichloroethylene, one of these chlorinated hydrocarbons, have been developed in Engineering Experiment Station Laboratory, Iowa State College. Trichloroethylene is a colorless liquid boiling at 86.7°C. with a specific gravity of 1.46 at 25°C. It is an excellent solvent for soybean oil, is non-flammable, and of a toxicity of the order of the usual petroleum fractions. Various alcohols such as ethanol and methanol have had limited application.
