Summary and conclusions
Rate-extractions of corn germ oil by heptane, isoheptane, and hexane at the same temperature showed the latter two to be better solvents than heptane. Extraction rate increased with the temperature.
Countercurrent extraction in a continuous laboratory pilot plant showed hexane at 157°F. apparently equal to iso-heptane at 192°F. It is suggested that the boiling of the hexane at 157°F. might account for the better extraction.
It can be concluded that hexane is at least as good a solvent for the extraction of corn oil from whole germ as is iso-heptane.
