By orthogonal design method, Catalytic activity of /ZrO2 solid superacid is studied, and the influence of catalyst characteristic and structure by manufacturing equipment is issued. It is concluded that the best prepared conditions of the superacid catalyst /ZrO2 for the synthesis of Octyl-Polyglycoside are followed:(1) PH=9.5; (2) calcined temperature at 500; (3) M(H2SO4)=0.5mol/L. Using this kind of catalyst the conversion of glueoside may reach as high as 96% in the synthesis of OCtyl-Polyglycoside and the selectivity is very high for the synthesis of Octyl-Polyglycoside. By introducing other metal oxide, the catalytic activity of complex solid superacid is studied.
Epoxidation of allyl chloride catalyzed by silica-based HTMS-3A was studied in chemical engineering. Under the selected conditions,the conversion of allyl chloride reached 65.6%,the yield and selectivity of epichlorohydrin were 63.9% and 97.6%,the yield of glycerol and heavier by-products were1.5% and 0.2% respectively. The stability of silica-based HTMS-3A in epoxidation of allyl chloride was studied: the conversion of allyl chloride decreased from 65.6% to 58.9%.The activity of the deactivated catalyst may be recovered by washing with hot acetone,or by calcinations
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
