[A spectrophotometric method for determining n-butanol]. 1988

N Bonev

The method for determination of n-butanol is based on its reaction with phloroglucinol in phosphoric acid media until receiving colour compound and followed by photometric measurements at 455 nm. The specificity of the reaction is studied concerning the n-butanol in the presence of about 15 other organic substances. The reaction is optimized after the method of Jouden.

UI	MeSH Term	Description	Entries
D007202	Indicators and Reagents	Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.
