Abstract

In research studies on the extraction of soybean oil by trichloroethylene it became necessary to determine small amounts of the solvent in the oil. For amounts above 10 percent trichloroethylene the simplest and best method for control purposes is by means of a specific gravity determination. Measamer (3) has shown that the trichloroethylene may be steam-distilled from the oil and weighed or measured. Three percent trichloroethylene in soybean oil may be determined with a maximum error of 10 percent. Greater accuracy should be possible in solutions containing more of the solvent. For amounts above 10 percent the method is more time consuming and no more accurate than the specific gravity method.
