Results and discussion

Preliminary study:
Comments: Under the preliminary test conditions, Khusinil was found to undergo marginal hydrolysis at pH 7 (12%), moderate hydrolysis at pH 9 (19%), but no significant hydrolysis at pH 4, after 5 days at 50 deg C. Under test 1 conditions, Khusinil was found to undergo a pseudo first order reaction, therefore, test 3 was carried out at 60 and 70 deg C at pH 7 and pH 9.  The results indicate that the half-life times at 25 deg C are greater than one year at pH 7 and between one day and one year at pH 9.
