AcetophenoneTxheej Txheem Tsim Khoom Txheej Txheem
Kev oxidation ntawm ethylbenzene tsim cov acetophenone, uas yog cov tshuaj cobalt lossis manganese acetates uas ua rau kub txog li 120–200°C kom tau txog li 90%. Kev sib cais ntau theem yuav tshem tawm cov phenylethane thiab hydroperoxides, ces cov tshuab distillation uas raug cais tawm cov acetophenone. Cov ntsuas qhov ntom ntom hauv kab yuav saib xyuas qhov huv ntawm cov distillate, ua rau muaj kev hloov kho qhov piv ntawm cov kua rov qab los ntawm lub sijhawm tiag tiag kom tswj tau ≥99.5% acetophenone, uas tseem ceeb rau kev siv tshuaj tsw qab. Kev tawm tswv yim qhov ntom ntom ua rau kev kuaj pom cov khoom tsis huv ntawm benzene thiab acetyl chloride yooj yim dua - kev tswj hwm qhov ntsuas qis dua 0.5% yog qhov tseem ceeb rau kev ntxuav acetophenone. Kev tswj hwm hauv kab tsis siv neeg ua kom cov piv ntawm cov kua rov qab los ntawm kev sib cais ntawm 2:1 thiab 3:1, txhim kho kev tshem tawm cov khoom tsis huv thiab txo cov yuam kev ntawm tes.
Thaum lub sijhawm oximation, dichloromethane extraction tswj cov organic theem ceev ntawm 1.045–1.050 g/cm³, saib xyuas ncaj qha siv Lonnmeter inline density instruments. Lub qhov rais ceev no tiv thaiv kev tsim ntawm oxime hydrolysate thiab tswj sodium hydroxide ntxiv. Qhov poob qis ntawm qhov ceev qhia txog kev rho tawm tsis tiav, ua rau muaj kev ua kom zoo dua ntawm cov extractant flow rate rau kev tsim cov acetophenone purity siab. Kev ntsuas inline tsav kev sib xyaw thiab kev sib xyaw ua ke, txhawb nqa cov qauv kev ntshiab acetophenone thiab kev tsim cov tshuaj tsw qab zoo.
