Abstract
The turbidity of suspensions of polymeric zinc monoglycerolate (ZMG) h as been used to determine dissolution rates in aqueous solution. The r ate was found to be first order with respect to the concentration of u ndissolved ZMG and of order 1/2 with respect to the hydrogen ion conce ntration in the pH range 4.1 - 5.8 and a temperature range of 20 degre es C - 45 degrees C. The temperature dependence at constant pH obeys t he Arrhenius equation and the activation energy of the dissolution pro cess was found to be near 35 kJ mol(-1).
