在此次工作中,我們試用了三种催化剂:Ⅰ,五氧化二釩沉淀于浮石上,Ⅱ,氧化鋅、氧化鎂、氧化鈣、氫氧化鋁、鉻酸鉀、硫酸鉀的混合物,Ⅲ二氧化錳和氧化鋁的混合物。用空气作氧化剂进行苊的脫氫,不能得到滿意的結果,其中催化剂Ⅰ不适宜于用作脫氫催化剂。用催化剂Ⅱ和Ⅲ在水蒸汽为稀釋剂的情况下,分别进行苊的气相催化脫氫得到比較滿意的結果。在此二种催化剂中以催化剂Ⅲ的結果比較好,最适宜的反应温度是600℃,脫氫产物的产量为90％,用光电比色法测出其中苊烯的含量为96％。
In this work, we tried three kinds of catalysts: Ⅰ, vanadium pentoxide precipitated on pumice, Ⅱ, zinc oxide, magnesium oxide, calcium oxide, aluminum hydroxide, potassium chromate, potassium sulfate mixture, A mixture of manganese oxide and aluminum oxide. Dehydrogenation of acenaphthene with air as oxidant did not give satisfactory results, of which catalyst I was not suitable as a dehydrogenation catalyst. With the catalyst Ⅱ and Ⅲ in the case of steam as a diluent, were respectively 苊 gas-phase catalytic dehydrogenation to get more satisfactory results. In these two catalysts, the result of catalyst III is quite good. The most suitable reaction temperature is 600 ℃, the yield of dehydrogenated product is 90%, and the content of camphene is 96% measured by photoelectric colorimetry.
