The analyses and rates of hydrolysis of Zectran, 4-dimethylamino-3,5-xylyl methylcarbamate are reported in aqueous media. These rates were measured in phosphate buffered, distilled water and in natural waters where temperatures of 10°, 20°, and 28°C. and pH values of 5.94, 7.00, and 8.42 were used. Initial concentrations of Zectran exceeded 60 mg/1 (0.27 mMol 1-1), whereas in the natural waters initial concentrations were 30 mg/1 (0.135 mMol l-1). This study shows that the persistence of Zectran in natural waters is, in large part, dependent upon the pH value and the temperature.
