英语翻译
在水溶液条件下,利用氢氧化钠作为反应催化剂,搅拌使邻硝基苯乙酮和邻硝基苯甲醛在非均相下进行羟醛缩合,合成2,2’二硝基查尔酮.通过在不同的温度和不同的催化剂浓度条件下得到的产物产率分析,得到最佳反应温度和最佳反应催化剂浓度,最后确定最优实验条件.通过实验结果分析,该反应最佳反应温度为24℃左右,NaOH浓度为1%左右,反应时间在18min左右,在此条件下反应产率最佳.
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!

Answer 1

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.：）
