摘要

Abstract

A systematic study of the synthesis of C.I. Acid Blue 9 leuco compound in water is reported. The kinetic analysis of experimental data for the condensation reaction between 2-formylbenzenesulfonic acid sodium and

-ethyl-

-(3'-sulfonic acid benzyl) aniline obtained at four different temperatures ranging between 85 and 100℃ is discussed. It is shown that the reaction followed second-order rate kinetics. The overall rate constant (

) increased with the increase of temperature. On the basis of the value of

activation energy (

) of the reaction was evaluated. Importantly

it is found that reactant concentration has great effect on the formation of C.I. Acid Blue 9 leuco compound

implying that it is not enough to improve the conversion of

-ethyl-

-(3'-sulfonic acid benzyl) aniline by only prolonging reaction time in the late period of the reaction.
