This new book gives you a complete explanation of sodium dispersions and the reasons for their use . . . how t h e increased surface area of the sodium particle in dispersion cuts reaction time . . . improves yields in sodium-organic reactions . . . reduces the amount of agitation needed . . . and makes possible many reactions that cannot be obtained with solid or molten sodium.

You'll read how sodium dispersions are used: in refining hydrocarbons . . . in Claisen condensations . . . i n preparing alcohol-free alkoxides, and in. halide condensations. If your processes call for metallic sodium i n any form, you'll find this book extremely valuable. Perhaps you can employ sodium dispersions t o cut reaction time a n d improve your product yield!
