| Abstract |
The use of 4-aminoantipyrine was proposed by Emerson in a new color test for phenols. As outlined by Emerson, the essentials of the reaction consist of bringing together the phenolic material, the 4-aminoantipyrine and an alkaline oxidant in a solution of sufficiently high pH to prevent the formation of antipyrine red. Potassium ferricyanide was recommended as the oxidant. The work to be described has had two goals: Evaluation of the reaction variables which affect usage of Emerson's reagent for the determination of the simpler phenols; and Devising a procedure sufficiently sensitive to detect a one p.p.b. concentration of phenol. |
