O n the Independence of Chemical Reactions

Oxidation of Propylene with Air over a Copper Oxide Catalyst

R. Aris and R. H . S. M a h , University of Minnesota

D.S. Billingsley and C. D . Holland, A B M College of Texas

Presents systematic procedure for evaluating stoichiometry of chemical reactions. Demonstrates by reference to a stirred tank reactor how such an approach may facilitate further studies of system.

Presents a method for correlation of data for catalytic reactions using mass transfer equations. Requires far fewer postulates than usual approach. Method demonstrated by correlation of results for catalytic oxidation of propylene. Same general approach should be successful with other catalytic reactions.

George J . Barenholtr, John E. Rutrler, Jr., and E. G. Bobalek, Case Institute of Technology System of epoxy adhesives on metal tested a t several temperatures, and a form of temperature-transportation principle applied to chemically stable variants. General equation derived defines strength-temperature relationships for all variants and makes it possible to predict strengths of adhesive joints over a wide temperature range. Results should be applicable to other chemically stable and amorphous polymeric adhesives. M s . 62-334

Nonsteady Flow of Viscous Fluids between Plane-Parallel Boundaries

John H . Ramser, Atlantic Rejning Company Exact equations for the velocity distribution and displacement are derived for the nonsteady, laminar flow of liquids constrained to move between plane-parallel boundaries. I t is assumed that the fluid is initially a t rest and that a constant pressure gradient is instantaneously applied in the presence or absence of gravity.

Pressure Drop in Horizontal and Vertical Concurrent Gas-liquid Flow

G. A. Hughmark, Ethyl Corporation Two general equations derived to represent pressure drop for gasliquid concurrent flow. O n e results in a form of drag coefficient, either positive or negative in sign, the other yields a lost work term, always positive. Data for horizontal, vertical upward and downward two-phase flow show lost work term dependent on pipe orientation. Lost work can he related to two-phase pressure drop and density of mixture in pipe to provide correlation method.

Minimum velocities, to convey mixed size materials pneumatically in horizontal flow without saltation, correlate with single particle saltation velocity of most difficultly transported particle size in mixture. Parameter in correlation is new constant (calculable from particle size analysis) characterizing size and spread of particle sizes in mixture. In combination with saltation velocity correlation, can be used as criterion for conveyability of materials.
