Daim Ntawv Thov Ntawm Tshuaj Reagent Distillation Thiab Rectification
Nov 06, 2021
Distillation thiab rectification yog tsuas yog siv rau cov kua los yog tshuaj reagents uas yuav tsum tau rhuab los ua kua, tshwj xeeb tshaj yog rau purification ntawm organic chemical reagents. Ua ntej distillation lossis rectification, qee zaum qee cov tshuaj reagents tuaj yeem muab ntxiv rau cov tshuaj tiv thaiv nrog impurities hauv cov tshuaj reagent kom huv si los tsim cov khoom kub (lossis qis dua) cov ntsiab lus kub, uas yooj yim dua tshem tawm thaum distillation lossis rectification.
Hauv distillation lossis rectification, thawj feem ntawm distillate thiab qhov kawg seem feem ntau raug tshem tawm. Qhov ntau ntawm ob qhov kawg raug tshem tawm, qhov siab dua qhov purity ntawm cov tshuaj reagents tau txais, tab sis qhov qis dua qhov tawm los.
