The colorimetric determination of alcohols

Kinetic Study of the Oxidation of tert-Butanol by Cerium(IV) in Perchloric Acid Media

“…A gradual increase in the rate was observed when adding sodium perchlorate. When analysing the results that were found, the rate constant values fit the following equation (r xy ϭ 0.9975): log k r ϭ Ϫ5.89(±0.10)ϩ4.12(±0.16)ΊI/(1ϩΊI) (1) where the origin ordinate actually is the logarithm of the corrected rate constant for the I-effect, k r (0). This result strongly suggests the existence of a kinetic salt effect for the reaction.…”

“…The use of cerium(IV) compounds as a quantitative colorimetric reagent in the analysis of alcohols it is well known [1,2]. The colorimetric technique is based on the formation of Ce IV -alcohol complexes.…”

Spectrophotometric method for the determination of ethanol in beverages and beer samples using cerium (IV) as reagent

“…The complexation of cerium(1V) with alcohols is known to be non-selective (Reid & Truelove, 1952). Further, cerium(1V) also reacts with reducing substances.…”

“…Cerium(1V) was used to detect and determine trace amounts of alcohols based on the red complexes formed with various alcohols (Reid & Truelove, 1952;Reid & Salmon, 1955). However, the method is not selective.…”

Portable platform for rapid and indirect photometric determination of water in ethanol fuel samples

“…The method is based on colorimetric complexation reactions between ethanol and cerium(IV), which generate deep orangered solutions. [22][23][24] Photometry is a good approach because it requires only simple and portable instrumentation and provides fast, selective, sensitive, and robust results. 25 This method is promising in the development of rapid testing tools as a result of the ease of making prototype systems, good analytical performance, portability, low cost, and reliability.…”
