Batch distillation yog dav siv rau kev sib cais ntawm cov khoom tshwj xeeb thiab cov tshuaj zoo thiab rau kev rov qab los ntawm me me ntawm cov kuab tshuaj thaum lub sij hawm tsim cov khoom purity siab thiab ntxiv cov nqi ntxiv. Batch Kev ua haujlwm yog qhov tseem ceeb ntawm kev lag luam tshuaj, biochemical, thiab tshuaj lom neeg tshwj xeeb.
Xav txog qhov no, dab tsi yog qhov txawv ntawm batch thiab nruam distillation?
Tus yuam sij Qhov sib txawv ntawm batch thiab txuas ntxiv distillation yog tus batch distillation ua tiav hauv pawg - ntse whereas tsis tu ncua distillation ua li a tsis tu ncua txheej txheem. Distillation yog cov txheej txheem tshuaj uas siv los cais cov khoom sib cais hauv a sib tov.
Ib yam li ntawd, vim li cas peb thiaj xav tau reflux hauv distillation? Reflux hauv dej haus distillation Los ntawm kev tswj qhov kub ntawm lub condenser, feem ntau hu ua dephlegmator, a reflux tseem tuaj yeem siv los xyuas kom meej tias cov khoom kub kub siab dua tau rov qab mus rau lub khob thaum lub teeb sib dua tau dhau mus rau qhov sib txawv ntawm cov condenser.
Kuj Paub, ua li cas txuas ntxiv distillation ua haujlwm?
Nruam distillation yog ib qho kev sib cais tsis tu ncua nyob rau hauv uas cov kua sib tov ntawm ob los yog ntau tshaj miscible Cheebtsam yog tsis tu ncua pub rau hauv cov txheej txheem thiab lub cev sib cais rau hauv ob lossis ntau yam khoom los ntawm qhov nyiam ua kom npau taws ntau dua (piv txwv li, qhov kub qis dua) cov khoom tawm ntawm qhov sib tov.
Dab tsi yog ib kab rectification?
Nyob rau hauv ib txwm siv los ntawm chemical engineers, ' kho kom raug ' yog tus txheej txheem ntawm concentrating ib volatile sib tov nyob rau hauv ntau volatile hom los ntawm countercurrent, multistage, vapor-kua hu. Qhov kev teeb tsa no yog hu ua fractionation kem los yog rectification kab.

Dab tsi yog qhov zoo ntawm fractional distillation tshaj qhov yooj yim distillation?
Fractional distillation yog qhov ua tau zoo dua hauv kev sib cais cov kev daws teeb meem zoo tshaj plaws rau hauv lawv cov khoom ntshiab dua li qhov yooj yim distillation. rau cov kev daws teeb meem uas sib txawv me ntsis ntawm Raoult txoj cai, txoj kev tseem tuaj yeem siv rau kev sib cais tag nrho
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog lub cev khoom siv hauv distillation los cais?
DISTILLATION yog kev ua kom huv ntawm cov kua los ntawm cua sov rau nws qhov kub thiab txias, ua rau vaporization, thiab tom qab ntawd condensing cov vapors rau hauv cov kua hauv lub xeev thiab sau cov kua. Kev sib cais ntawm ob lossis ntau dua cov kua yuav tsum muaj qhov sib txawv ntawm qhov kub thiab txias
Dab tsi yog cov khoom siv hauv distillation?
Khoom siv 2 Erlenmeyer flasks. 1 1-qhov stopper uas haum rau lub raj mis. 1 2-qhov stopper uas haum rau lub raj mis. Yas tubing. Ntev ntev ntawm iav tubing. Kev da dej txias (txhua lub thawv uas tuaj yeem tuav tau ob qho dej txias thiab lub khob) Boiling nti (ib yam khoom uas ua rau cov kua dej npau npau ntau dua thiab sib npaug) Kub phaj
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
