Study on treatment and modification of Binh Thuan bentonite by Zn2+ to catalysis for diels-ander reactions of anthracene with anhydride maleic
Abstract
BenLG, BenH and BenZn were preparated by modification from Binh Thuan bentonite . The catalytical characteristic of modificated bentonite were studied by chemical analysis, XRD, TGA-DTG, BET and, BJH. The catalytic activity of modificated bentonite were studied on Diels-Alder reaction between anthracene with anhydride maleic. The structure of reaction product was deteminted by 1H-NMR, 13C-NMR, HSQC, HMBC and NOESY. Some conditions of Diels-Alder reaction were tested and optimal reaction conditions were BenZn, 120 minuts, 170oC, 80 atm, C6H5NO2.
