Now BIGGER and BETTER than ever!
The CONDENSED CHEMICAL DICTIONARY New 6th Edition edited by ARTHUR and ELIZABETH ROSE Applied Science Laboratories, Sfale ("oileye, Pa. FIRST PUBLISHED in 1919, the world-famous "(J. C. Ό . " has grown
tremendously through five editions. This new sixth edition now appears in a larger, 6 Γ, / 8 Χ 9 :{ / 4 format to accomodate the abundance of new infor mation—the kind of information that makes this one of the most indispens able chemical reference works ever published. The addition of thousands of new entries, the deletion of obsolete infor mation, and complete revision all along the line have required five years o! intensive effort. For example, the new elements discovered as recently as June, 1961, and all the terminology relating to such current topics as rockets, thermonuclear phenomena, and plasma are included. Official pharmaceuticals and drugs an» covered completely, plus an excellent repre sentation of trademark and generic names not yet official. Formulas are mostly improved to show structure, and there is greatly expanded information on new derivations and new uses. All trademarked items give the name of the manufacturer from whom the information was obtained. Here is a sampling of the important new or growing fields or types of compounds covered in the sixth edition: • Polymers (both individually, i.e., polypropylene, and collectively, i.e., polymer structure and stereospecific polymers) • Ferrites (useful in electronics) • Pesticides (many new ones) • New fibers · J'fasticizers • Ferrocenes (''sandwich molecule.- useful at high temperatures) Very high-purity materials (as used in transistors, etc.) Nuclear chemistry (completely revised bv an expert in the biochei ical field).
