| Summary: | Because of the high molecular weight of water soluble polymers used in Enhanced Oil Recovery (EOR) technique, only a small of polymer will bring about a substantial increase in water viscosity. Hydrolysis of polyacrylamide under basic conditions was studied with emphasizing on the kinetic aspect.
Polyacrylamide was derived from polymerization of acrylamide using mixed solvent precipitation method. Hydrolysis of polyacrylamide was carried out in batch reactor equipped with a stirrer, thermometer, condensor, and heater. A solution of sodium hydroxide was put in the reactor and heated to the desired temperature. When the desired temperature was reached, polyacrylamide was introduced quickly in the reaction medium. During the process, the temperature was kept constant. Samples were taken from the reaction medium at a regular time then analyzed by acidi-alkalimetri method. The effects of temperature, concentration of sodium hydroxide and concentration of amide in water to k', were studied in this investigation.
It could be concluded that the reaction was found to be pseudo 1.4 order with respect to the amide. Temperature and catalysts concentration affected the reaction rate constant. The correlation developed by operation condition for the reaction rate constant were :
a. Temperature in range of 400C (313 K) to 900C (363 K), k' = 0.93118745 e
2766.91/T , average error 3.72 %.
b. Catalysts concentration in range of 0.3 to 0.8 N,
k' = 2.627728.10-3 e(3.567011 Ckat -1365.24/1) , average error 16.53 %
c. The generalized correlation : k'= 0.118777 e(3,71425. Ckat - 2680.933/7) , average error 10.88 %.
