SELECTS ALCOA ACTIVATED A L U M I N A FOR WORLD'S FIRST SYNTHETIC GLYCERINE PLANT Close control of reactions is one of the many secrets of success in Shell Chemical Corporation's new synthetic glycerine plant. The raw material, propylene, must be quite pure as well as dry. Side reactions which introduce extraneous compounds m a k e the desired reaction more difficult to complete.
tionable changes in form or properties. It does not swell, soften or disintegrate. ALCOA Activated Alumina has hig^h resistance t o shock and abrasion, is non-corrosive and practically iron-free. ALCOA Activated AJumina dries gases, vapors and organic liquids to d e w points as low as minus 100° F. Y e t its stability and purity make it an economical desiccant where higher d e w points suffice.
I t is essential, therefore, that the desiccant used for drying the raw material must, itself, be pure, uniform and highly inert.
