| Abstract: | Z\-rO\-2-Fe\-2O\-3-S\-nO\-2/SO\ \{2-\}\-4 complex solid acid has beenprepared by chemical coprecipitation with ethylene glycol used as a dispersant.Factors were investigated that have effects on acid strength such as the molarratioes,the concentiation of sulfite acid, the duration of acid dipping, the firing temperature and the period of firing.Also inspected was the catalyst activity in the esterification of ethyl acetate. |
