Abstract

The S tephens-M orris disc column is used to study the influence of chemical reaction upon the rates of absorption of chlorine from air by solutions of either cyclohexene or oleic acid with iodine in carbon tetrachloride. The increase in the liquid film coefficient due to chemical reaction between chlorine and cyclohexene was found to be independent of the concentration of cyclohexene, but no satisfactory correlation of the experimental results could be obtained. The fractional increase in the liquid film coefficient due to reaction between chlorine and oleic acid varied from zero to 9, and was found to be ▪ where φ is the ratio of the liquid film coefficient to the coefficient in the absence of reaction, c C is the concentration of the catalyst (iodine), c B is the concentration of oleic acid, and c i is the concentration of the dissolved chlorine at the gas-liquid interface. The units are lb. moles, feet and hours. The film theory is unable to predict the effect of the chemical reaction on the liquid film coefficient.
