第一段翻譯如下
The experiment takes carbolic acid as raw material , adopt acetophenetidin-rization, Fries weight row , the oxime have molten , Beckmann weight row combining method has got target outcome to acetophenetidin aminophenol, total recovery is under using acetone as catalysator in the best reaction temperature and the best reaction time: 40.5%.
第二段翻譯如下
Different in having discussed Fries weight row process by experiment of equal rank operation way has collected the effect leading to outcome , the effect having studied reaction condition collects rates's in Beckmann weight row to target outcome has optimized and technological conditions. The structure being in progress to main outcome by the fact that melting point determines the instrument admeasurement and the infrared spectrometer identifies an at last.
文章有些長、、望認真看完、、標準人工翻譯、、希望可以幫助你、、
