Nitrogen-1 5 Tracer Studies of the Nitrolysis of Hexamethylenetetramine. H M X and R D X formation by hexamine nitrolysis
without (CH20) is essentially from hexamine-nitrogens. With (CHzO), in situ, 7% of the H M X and 40% of the R D X are derived from NH4NOa.

Theory of the Surface Ignition Energy of Condensed Explosives. Simple theory, that elucidates important features of
surface ignition energy and delay time of an explosive under high heat flux, is developed from the heat conduction and thermal decomposition kinetic processes involved.

Second Virial Coefficients for the Lennard-Jones (6-m) Gases.
DTA to study of decomposition of organic systems, particularly those of interest as lubricants a t high temperatures. Samples of several distinctly different classes of materials used. Data show utility of procedures for screening materials for thermal stability.
Agreement between calculated and experimental values of coefficients for argon, carbon dioxide, methane, ethane, propane, and n-butane is improved by choosing different m values for each substance. More accurate representation of data for pure gases and a better combining rule for prediction of properties of gas mixtures is foreseen.

of differential rate equations representing the reactions of a C7 hydrocarbon catalytic reforming sequence. The effect of temperature and reactor size of conversion in an adiabatic process is presented.
Timewise variations in collapsing velocity, fluid pressure, and rate of energy dissipation are nonmonotone in power-law fluids, and it is feasible to alter or control dynamic characteristics of the bubble in a Newtonian fluid by addition of a power-law fluid.

Predicted Burning Roles of Single Carbon Particles. Recent comprehensive theory of carbon combustion in air is summarized and used to reanalyze original data of Tu, Davis, and Hottel. Analysis shows that desorption is the rate-controlling step below 1000° K.; above, it is shared by chemisorption and diffusion.

Mass Transfer-Controlled Kinetics.
A Simplified Approach.
Under certain conditions, the concentration of reacting species at a solid-gas interface is shown to equal the concentrations obtained when the bulk gas is brought to equilibrium with the solid phase. This result leads to a simplified form of kinetic expression for mass transfer-controlled reactions. Samuel E. Craig, Jr., Arizona State University
