“…The titration characteristics of various bis(disubstituted phosphinyl) alkanes and trisubstituted phos- Other Functional Groups. Dijkstra and Dahmen (47) have developed a convenient method for the determination of a-epoxy compounds. The titration is carried out directly in acetic acid medium with perchloric acid titrant.…”

A lthoughthere have been no dra-_£\_ matic "breakthroughs" during the last two years there has been notable advance in several areas. Particularly gratifying is the number of outstanding papers devoted to the fundamentals of nonaqueous equilibria. Not only are some of the more commonly used solvents such as acetonitrile receiving continued attention, but theoretical studies are being extended to solvents of very low7 dielectric constant. There appears to be a trend toward utilizing the newer types of measurements such as nuclear magnetic resonance and toward using several different types of measurements in the same investigation. In some of the recent work, for example, one finds spectrophotometric, conductometric, potentiometric, and solubility measurements combined to achieve an understanding not possible with a single technique. In the area of study concerned with the effect of solvent and acid structure on acidity, new and imaginative ideas have been introduced.

“…Other sorbents studied include: carbon black (1365), silk fibrion (24), factice ( a polymer derived from soybean oil) (799), porous glass (728), spherical agarose (800), and a three-dimensional polymethacrylate (2248). Methods were described for packing alumina columns (1303), for preparing permanent silica gel columns (425), and for automatic packing of Sephadex columns (2246).…”
