3A Molecular Sieve Rau Adsorbing Trace Moisture hauv Ethyl Acetate Solution
Ethyl acetate feem ntau muaj cov dej noo, uas ua rau azeotrope nrog ethyl acetate. Nyob rau hauv ib txwm siab, azeotrope muaj 8.5% dej los ntawm huab hwm coj. Yuav kom tau txais high-purity ethyl acetate, ethyl acetate yuav tsum tau ua kom zoo. Feem ntau siv cov txheej txheem refining feem ntau suav nrog: txheej txheem extraction refining; azeotropic distillation nrog tas li boiling tus neeg sawv cev thiab acetic acid extraction cov tshuaj tiv thaiv distillation txheej txheem, thiab lwm yam. Cov txheej txheem saum toj no refining siv ntau lub zog.
3A molecular sievemuaj cov nyhuv adsorption muaj zog ntawm cov dej noo, thiab nws yooj yim rau kev khiav lag luam thiab yooj yim rau regenerate. Siv 3A molecular sieve rau adsorb noo noo nyob rau hauv ethyl acetate tov, high-purity ethyl acetate tau ncaj qha, thiab cov txheej txheem ntau lawm yog yooj yim thiab lub zog noj yog tsawg.
Cov txheej txheem rov ua dua tshiab hauv cov txheej txheem cyclic adsorption ntawm 3A molecular sieve, nqus cov nyhuv tom qab kev tsim kho dua tshiab, thiab cov qauv hloov pauv thiab ua rau sab hauv molecular sieve tom qab cyclic adsorption xav tau kev kawm ntxiv, txhawm rau txo qhov deactivation tus nqi ntawm molecular sieve thaum tuav lub adsorption nyhuv ntau npaum li sai tau.
