邻硝基苯乙酮 1-(2-nitrophenyl)ethanone
邻硝基苯甲醛 2-Nitrobenzaldehyde
查尔酮 1,3-bis(2-nitrophenyl)prop-2-en-1-one
我怎么看着这么别扭啊,composing 2 , 2 without exception each other' 。。。。。。。真的看不懂
希望有更好的答案哈,在线自动的就免了!
Under aqueous solution condition, make use of sodalye to be reaction catalysator, mixing makes 1-(2-nitrophenyl)ethanone and 2-Nitrobenzaldehyde be must go down two nitro group carrying out hydroxyl aldehyde condensation , composing 2 , 2 without exception each other' 1,3-bis(2-nitrophenyl)prop-2-en-1-one. By the outcome under the different temperature and different catalysator thickness condition, productivity analyses, Get the best reaction temperature and the best reaction catalysator thickness , ascertain optimum experiment condition finally. The temperature is controlled by 24 degree by the fact that the experiment bear fruit analysing , owing reaction best reaction , NaOH thickness is controlled by 1% , the minute controls reaction time in 18 , condition goes down reaction productivity best here.
希望能帮到你 :)
