dc.description.abstract | The disaccharides called sucrose not hydrolyze in aqueous solution; the reaction is known as sucrose inversion, is catalyzed by mineral acids, and can be studied by the polarimetric method. Treaties chemical kinetics fit this kind of reaction order n = 1, [1- 4]; the reaction rate depends on the concentration of sucrose, being considered a chemical reaction of zero order towards water. Specialty papers mention that the order of reaction might be determined by graphical integral method; plot, towards values of reaction times, four functions of sucrose concentration ( 2t ct , lnct , 1 ct ,1 2c ). This paper proposes a modern kinetic study on acid hydrolysis of sucrose, without mechanical agitation of reactant mixture. The multiple measurements were made with automatic polarimeter, and objective experimental results were processed with a computer; the software offers additional information on the dispersion of experimental data, and the results are outstanding. | en_US |
