Lub Melting Point ntawm EtOAc cuam tshuam li cas rau kev khaws cia thiab kev thauj mus los?
Ethyl Acetate (EtOAc) muaj qhov taw tes qis heev ntawm -83.6 degree, uas ua lub luag haujlwm tseem ceeb hauv kev thauj mus los thiab kev ruaj khov.
Cov txiaj ntsig tseem ceeb:
- Tseem ua kua nyob rau hauv huab cua txias heev
- Tiv thaiv kom ruaj khov hauv lub caij ntuj no logistics
- Ua kom ruaj khov twj tso kua mis thiab kev hloov pauv kev ua haujlwm
- Txo kev pheej hmoo ntawm crystallization hauv cov tank cia
Cov ntaub ntawv txhawb nqa:
- Melting Point: -83.6 degree
- Freezing pheej hmoo tsam: xyaum tsis saib xyuas raws li ib txwm muaj kev lag luam
- Kev ua haujlwm kub ntau: -50℃rau +40℃kev nyab xeeb kev tuav
Qhov no ua rau Ethyl Acetate muaj kev ntseeg siab heev rau cov khoom siv thoob ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj qhov hloov pauv ntawm lub caij ntuj sov.
