MICROSCOPIC GIANTS These are sodium dispersions—highly magnified parti cles of one of industry's most useful metals. And, para doxically; the smaller they are, the harder they work. By exposing far greater surface area, sodium dispersions speed reaction time—make possible many chemical re actions once considered impractical. What are you interested in? Sodium alkoxides, organometallic compounds, Claisen condensations, Wurtz type
reactions? Purifying hydrocarbons; reducing metal halides, a polymerization 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. Tor more information, simply call or write.
