“…To carry out this program successfully, it is necessary to have a simple yet reliable method of calculating the burning velocity from the flame dimensions. Although there are a number of methods for determining burning velocities from Bunsen burner flame cones, those which have a reasonable theoretical basis and give reliable results require somewhat detailed measurements or calculations (14,15,19,31,33,34). This report presents a simple procedure which requires a minimum of calculations to obtain reliable results with data demonstrating the errors involved, a comparison with results from other laboratories, and the burning velocities of 77 compounds showing the effect of molecular structure on burning velocity.…”

“…Oxygen Is Extremely Rapid The oxidation of carbon monoxide as a secondary reaction accompanying the combustion of carbon and the oxidation of hydrogen are extremely rapid gas-phase reactions. This reaction has been studied by a number of investigators (5,17,20,117,132,173). Falk (75), through a measurement of ignition temperatures, found that the reaction between hydrogen and oxygen was bimolecular, with a temperature coefficient of 1.31 per 18°F.…”

PROCESS DEVELOPMENT tion, through the agency of hypochlorous acid, of the aldehydes to the corresponding acetic acid, dichloroacetic acid, and trichloroacetic acid. Both types of side reaction can be controlled through proper arrangement of temperature and conditions pertaining to the introduction of chlorine. The chlorination can be carried batchwise, but is most efficiently managed on a semicontinuous or completely continuous basis.
