Notes:
The rate of reaction of ferricyanide with n-octyl mercaptan solubilized in polystyrene latex has been measured. The mercaptan was dissolved completely in the latex polymer particles before the addition of ferricyanide. The latices were prepared with potassium myristate, sodium tetradecyl sulfate, and dodecylammonium chloride, as surfactants. In each latex the reaction was first-order to ferricyanide, mercaptan, and hydroxyl ion. The rates in myristate and tetradecyl sulfate latices were approximately equal, but smaller by about five orders of magnitude (extrapolated to the same pH) than the rate in the dodecylammonium chloride latex. The reaction apparently occurs on the surface of the polymer particles and thus is favored in the latex with positively charged particles on the surface of which the ferricyanide is adsorbed as counterion.
