Promising method recovers naval stores from decayed stumps of Southern pine. May have application to waste wood from variety of operations in lumber and paper industries. Heat of grinding vaporizes most of turpentine and pine oil. Remainder easily distilled a t 250’ F. At 440’ F. three quarters of rosin is distillable; rate favored by increasing partial pressure of steam.
Velocity of propagation of rarefaction waves in wet steam found to have constant value, independent of mixture quality, and approximately equal to acoustic velocity in dry steam. Reynolds’ description of critical flow phenomenon appears valid for wet steam within the experimental range (pressure between 14.7 and 45 p.s.i.a., and grossquality between 5 and 100%).

Wetting Agents and Inhibitors in Hydrochloric Acid Solutions Purification of Organic Solutes by Simultaneous Complexed Anion and Sulfate-Bisulfate Anion Exchange Procedures
J . C. Hesler and K . A . Schmidt, Nalco Chemical Company Specialized technique for low cost purification. Where metal forms a stable anionic complex a t low or moderate acidities, and is decomposed in very low acid media (or in water), removal of both metal salt and free acid is very economical. Extension of technique to other complexing acids and metals from nonionized solutes suggested.

The Development of the Houdry Detol Process
A . H. Weiss and Lee Friedman, Houdry Process and Chemical Company Gas Absorption i n Agitated Gas-liquid Contactors. Interfacial Area, Gas Holdup, llquld Phase Mass Transfer Coefficient, and Reaction Factor
Fumitake Yoshida and Yoshiharu Miura, Kyoto University, Japan Liquid phase mass transfer coefficient in agitated gas-liquid contactors can be correlated as function of Reynolds number for the agitator, with average bubble diameter as principal dimension and liquid phase Schmidt number. When absorption is accompanied by moderately fast first order or pseudo-first order reaction, reaction factor can be estimated by theoretical equations under certain conditions.

A Study of the Effect of Concentration on the Lewis Model For Gas-liquid Mass Transfer
R . K . Gibbsand D . .ld. Himmelbiau, Universiiy
fo,
Texas
The Lewis model is a reasonably satisfactory model for interphase transport of COP in gas-liquid systems under consistent hydrodynamic conditions. Although rate “constant” for mass transfer changes somewhat with gas or liquid concentration, variation under normal conditions is moderate in contrast to nonideal liquid-liquid systems.
BORAX TO BORANES With preface by PROFESSOR THOMAS WARTIK Pennsylvania State University This is a collection of 27 papers given at two ACS symposia (1958 and 1959) on the production of boron hydrides from borax, and on the chemistry of the boranes. Five papers are included on the fundamental chemistry of boron, and one on the history of this element and its compounds. Among the applications of boron and the boranes discussed in this definitive monograph are those to nuclear reactors, “exotic” jet engine and rocket fuels, and semiconductors. Boron is, because of its electronic structure, an extremely versatile element and forms a great variety of compounds of potential but unrealized usefulness. Boron chemistry is one of the new frontiers in organo-inorganic chemistry. Therefore, this volume is of interest and importance to chemists in any of the fundamental fields, as well as to specialists in the theory of valency, crystal structure, metallo-carbon compounds, the chemistry of explosion, and the history of chemistry.
