To determine the possibility of improvement of the process of CO2 removal by absorption with alkanolamines, densities, viscosities, and refractive indices of four aqueous alkanolamine solutions (water + monoisopropanolamine (MIPA), diisopropanolamine (DIPA), triisopropanolamine (TIPA), or diethanolamine (DEA)) were measured in the temperature range ...

Indirect (IBil), direct (DBil) and total (TBil) bilirubin are important clinical indicators of hepatobiliary diseases, which require rapid detection in diagnosis and treatment. IBil and DBil have a structural relationship with several macromolecules in hepatobiliary metabolism.

9-Methylfluorene was tested as an indicator in the titration of commonly used organometallic reagents. This indicator is readily prepared in three steps from fluorenone. In THF solution the deprotonated indicator is red and exhibits a sharp endpoint.

Features are established for formation of flux-cored wire spatial movement trajectories in relation to its parameters and rate of introduction, and possible areas of filler release are identified. A procedure is developed and a nomogram is constructed for evaluating existing technologies of steel treatment with flux-cored wire containing calcium ...

A rapid titration procedure is recommended for the estimation of Na2S2O4 in commercial sodium dithionite (sodium hydrosulphite, sodium hyposulphite) and in aqueous solutions of this compound, using potassium hexacyanoferrate(III) as reagent and methylene blue as indicator.

ABSTRACT A robust, stability-indicating isocratic HPLC method for the quantitation of cromolyn sodium and its related substances was developed and validated. The two known synthetic impurities likely to be present in cromolyn drug substance, designated as impurity 1 and impurity 2, are non-ionic compounds while cromolyn is a weak acid.
