Studying why fruits taste that way. E.K. Nelson of the Department of Agriculture is shown making tests with an apparatus which the Department imported from Germany for the purpose of studying the essential oils or "flavor-giving" content of fruits and vegetables. At present chemists are acquainted with the essential oils of only a few fruits, such as some of the citrus group. The apparatus is a vacuum distill which permits the distillation of liquids at temperatures much lower than usual by reducing the pressure, 1/10/31

Production of butylene glycol. Butylene glycol is recovered from corn fermentation liquors in an experimental still in the pilot plant of the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. This is one step in the Department's research that led to the development of a fermentation method for converting corn into butylene glycol, a chemical that can be used in making anti-freeze for automobiles and in the production of commercial solvents for various manufacturing purposes. Research now is directed toward the development of a practical way to turn the butylene glycol into butadiene, from which synthetic rubber can be made. The work has already been done on a laboratory scale
