Abstract

The Bray-Liebhafsky (BL) oscillatory reaction generated in the batch reactor at 62- 68 oC was perturbed by cobalt(II)-nitrate, supported on the macroreticular copolymer of poly-4-vinylpyridine with divinylbenzene (Co-PVPDVB). The kinetic data was analyzed of the complex pathways of the hydrogen peroxide decomposition in the examined BL reaction. The obtained results confirm that the kinetics of the BL reaction in the presence Co-PVPDVB comes partially from the Co-catalyst and partially from the macroreticular copolymer support.

Oscilatorna reakcija Bray-Liebhafsky (BL) realizovana u zatvorenom reaktoru na temperaturi 62-68 oC je perturbovana sa kobalt(II)nitratom ugrađenim na makroretikularnom kopolimeru poli-4-vinilpiridina sa divinilbenzenom (Co- PVPDVB). Analizirani su kinetički podaci kompleksnih reakcionih puteva razlaganja vodonikperoksida u ispitivanoj BL reakciji. Dobijeni rezultati potvrđuju da je u prisustvu Co-PVPDVB kinetika BL reakcije delimično određena Co-katalizatorom, a delimično makromolekularnim kopolimernim nosačem katalizatora.
