MICROSCOPIC GIANTS These are sodium dispersions—highly magnified particles of one of industry's most useful metals. And, paradoxically, the smaller they are, the harder they work. By exposing far greater surface area, sodium dispersions speed reaction time—make possible many chemical reactions once considered impractical. "What are you interested in?

reactions? Purifying hydrocarbons, reducing metal halides, a potymerization catalyst? Try sodium dispersions. One of our Chemical Engineers will help you evaluate their reactions or assist you in preparing your own dispersions. He'll also discuss the most efficient techniques in manufacturing, storing, diluting and handling these microscopic giants· For more information, simply call or write.
