Реферат:
Correlations of the initial rates of butene and dibutyl ether formation from 1-butanol at 300 °C with strength and concentration of aprotic sites on aluminium oxides modified with various ions were examined. It was found that in the formation of dibutyl ether, weak aprotic acidic sites were active. Their specific activity increases with increasing strength of the sites, defined as the heat of adsorption of carbon monooxide, up to the value of 40 kJ/mol. The strongest aprotic sites do not take any important part in the reaction. In butene formation, both types of aprotic acidic sites, weak and strong, are active. It was found that the selectivity in 1-butanol dehydration depended on the concentration of stronger basic sites.
