TitleMicro Determination Study and Organo physical properties of 2-Aminophenol and Catechol with 4-aminoantipyrine in the Presence of Potassium Iodat.
Untitled
Abstract

A simple, sensitive and selective method has been developed for the determination of 2-aminophenol and catechol with 4-aminoantipyrine. The method is based on the reaction of 2-aminophenol and catechol with 4-aminoantipyrine and potassium iodate at pH 3.7 and 3.3 respectively. The reactions gave an intense water soluble color products that have maximum absorption at 427, 378 nm and ?max0.19104 and 0.12104 for 2-aminophenol and catechol respectively . A linear correlations (1-9 ?g ml-1) for both compounds were found between absorbance at ?max and concentration. The results obtained are both precise (RSD were better than 1.3 % and 2.2 % respectively) and accurate (relative error were better than 0.03 % and 0.4 %) . The colored products were found to be 1:1 for 2-aminophenol:4-aminoantipyrine and catechol : 4-aminoantipyrine . The stability constants and the rate constants of the reactions under optimized conditions and at room temperature were 0.1×103 L.mole-1, 1.8×10-2 min-1 and 3.5×104 L.mole -1 , 2.6×10-2 min-1 respectively. Key words: 4-Aminoantipyrine, Catechol and[2-Aminophenol, Spectrophotometry .
