A SELECTIVE KINETIC METHOD FOR THE ESTIMATION OF BENZYL ALCOHOL IN CLOSELY RELATED MIXTURES

Ethylenebis(biguanide)silver(III) ion quantitatively oxidises benzyl alcohol and its derivatives (XC 6 H 4 CH 2 OH; X = H, CH 3 , Cl or NO 2 , substituents in ortho or para position). The difference in reaction rates for different alcohols has been utilised in developing a kinetic method for the est...

Description
Summary:Ethylenebis(biguanide)silver(III) ion quantitatively oxidises benzyl alcohol and its derivatives (XC 6 H 4 CH 2 OH; X = H, CH 3 , Cl or NO 2 , substituents in ortho or para position). The difference in reaction rates for different alcohols has been utilised in developing a kinetic method for the estimation of benzyl alcohol (2.0-40.0 mmol dm −3 ) in the presence of a large number of closely related alcohols and hydroxy compounds. The relative standard deviation for ten replicate measurements of 5 mmol dm −3 benzyl alcohol is 1.5%. The method was satisfactorily applied to analyse real samples.
