| Research Abstract |
Solid super acid catalysts, <SO(_4^(2-))> / <TiO_2> and <SO(_4^(2-))> / <ZrO_2> were investigated their preparation which can procuce highly and stable active sites in their surface, and their use in which the catalysts prepared can exhibit their reaction selectivity. For the purpose, firstly the preparation technique for <TiO_2> and <ZrO_2> as catalyst supporter was examined from the standpoint of their pore structure, and secondly the sulfuric acid treatment to support <SO(_4^(2-))> ions on their surface, and the calcination conditions to activate sites adsorbed the ions partly up to the super acid sites were made clear.
The reaction selectivity due to the diffusion of reaction spieces within the pores in the catalysts was shown more excellent manner in vapor phase-solid catalyst in through bed reactor than in liquid phase-solid catalyst suspension in tank reactor. The test reaction for the catalyst activity was the esterification between alcohols and carboxylic acids in the excess of alcohols, mainly between methyl alcohol and acetic acid.
The result of the vapor phase esterification of acetic acid to several alcohols showed that these catalysts catalyze each reaction system to the different extent in primary alcohols with different bulkiness of alkyl groups.
