Kev siv
- Kaus: Acetoniturile yog cov organic zoo heev, siv rau kev rho tawm thiab sib cais ntawm butadiene thiab lwm tus olefins hauv kev lag luam petrochemical; hauv kev lag luam kws tshuaj, feem ntau nws siv nyob rau hauv synthesis, crystallisation thiab rho cov tshuaj; Hauv kev lag luam hluav taws xob, nws tuaj yeem siv rau kev ntxuav hluav taws xob.
- Cov khoom siv raw rau cov synthic: ace yog cov khoom siv tseem ceeb rau cov khoom sib txuas, thiab lwm cov tshuaj, thiab muaj peev xwm siv tau rau kev npaj cov khoom siv tshuaj lom neeg xws li acrylonitrile .
- Kev tshawb xyuas cov tshuaj tiv thaiv kab mob: hauv kev tsom xam tshuaj lom neeg, cov pa roj ntsha ua kua chromatography (HPLC)
