Title: Kinetics of drug decomposition. Part 48. Specific acid-base hydrolysis of rolitetracycline. Author: Pawelczyk E, Plotkowiak Z. Journal: Pol J Pharmacol Pharm; 1977; 29(4):451-9. PubMed ID: 20613. Abstract: Using chromatographic-spectrophotometric method, the effect of H+ and OH- ions on the rate of hydrolysis of rolitetracycline (RT) to tetracycline (T) at 20degreeC was investigated. The advantage of this analytical procedure over the direct fluorescence or UV absorption measurements of RT solutions during the kinetic investigations in HCl medium was demonstrated. The catalytic rate constants (kH+ and kOH-) for the hydrolytic degradation of RT under oxygen-free conditions are given.[Abstract] [Full Text] [Related] [New Search]
