A method for determining the composition of acetone, hexane and water mixtures was adapted for use with acetone, cyclohexane and water mixtures. Techniques for drying cottonseed flakes to different moisture contents for extraction with acetone‐cyclohexane azeotropes were devised. Tests for possible gossypol binding occurring during the drying operation were made. Bench scale extractions yielded data which show the water resulting in miscellas when extracting cottonseed flakes at various moisture levels. It is envisioned that in a commercial process utilizing an acetone‐cyclohexane‐water mixture to produce cottonseed protein products for food uses, the water in the extracting mixture would be stablized at a level somewhere between the 0 and 3% by wt water levels of the two azeotropes used in these studies. Efforts are currently being devoted to defining the optimum practical water level that could be easily attained in commercial usage. Additional products evaluations will also be made.
