訂正日: 2010/06/28 訂正理由: - 訂正箇所: 論文抄録訂正内容: Wrong : Reduction of butyraldehyde by ethyl alcohol proceeded with fairly high velocity and the decomposition of butyraldehyde was not so much accelerated. Reduction of crotonaldehyde yielded both of crotonalcohol and butyraldehyde, but which route is the main reaction could be determined. Isomerization of crotonalcohol to butyraldehydee is possible but the reaction velocity is not so high. Formation of n-butanol from ethanol seems difficult to proceed only by the reaction route including no reduction of double bond. Formation of butadiene by the dehydration of crotonalcohol is difficult below 350°c. The reaction of ethanol can be explained as a first order reaction including retardation term. Acetaldehyde, formed as a by-product in the reductoin proceeded by ethanol, even occupies about 60% of total acetaldehyde concerned in the condensation reaction of ethanol at the reaction temperature of 450°c.
