(1) Alkalimetric pH-stat titrations of cephalosporin C, cephacetril and their deacetyl derivatives using an acetyl esterase and beta-lactamase are described.
(2) An alkalimetric method was used to determine the enzyme activity and to estimate its inhibition by 6-amino-penicillanic acid derivatives.
(3) Alkalimetric, spectrophotometric, NMR, and resonance Raman titrations are reported for the sulfonamide Neoprontosil in aqueous solution.
(4) The advantages of the proposed method are good stability of sodium borohydride volumetric solution and insensitivity of titrated systems to CO2 from the atmosphere, which is unavoidable with alkalimetric titrations in aqueous and non-aqueous systems.
(5) A potentiometric acidi-alkalimetric titration, carried out in nonaqueous solution with the application of a titriprocessor is applied as an assay.
Alkalimetry
Definition:
(n.) The art or process of ascertaining the strength of alkalies, or the quantity present in alkaline mixtures.
Example Sentences:
(1) The amount of synthesized ester was estimated by alkalimetry, and products were identified by thin-layer chromatography and infrared spectroscopy.
