Applicant's summary and conclusion

Conclusions:
The Hydrolysis rate constant of 5-hydroxyisopthalic acid is estimated to be 0.0000000000036604 (3.6604 E-12) cm3/molecule-sec. at half life of the 35.065 hrs.The estimated half life of the substance indicates that the substance is slowly hydrolysable.
