Qhov ntom ntom ntawm Ethyl Acetate: Kev Ntsuam Xyuas Kev Ntsuas thiab Kev Siv Ua Haujlwm
Ethyl Acetate yog cov organic hnyav siv nyob rau hauv ntau yam kev lag luam thiab chaw kuaj mob. Kev nkag siab txog qhov ntom ntom ntawm Ethyl Acetate tsis yog tsuas yog ib qho tseem ceeb rau kev tsim tshuaj lom neeg, tab sis kuj pab txhim kho nws cov txiaj ntsig zoo hauv cov ntawv thov sib txawv. Hauv tsab xov xwm no, peb yuav tham txog qhov ntom ntawm ethyl acetate thiab cov xwm txheej cuam tshuam los pab koj nkag siab zoo dua cov khoom tseem ceeb ntawm lub cev.
Lub ntsiab lus ntawm qhov ntom ntom ntawm Ethyl Acetate
Qhov ceev ntawm ethyl acetate yog qhov loj ntawm ib chav tsev ntim ntawm ethyl acetate ntawm qhov muab kub thiab siab. Feem ntau, qhov ceev yog ntsuas hauv g / cm³ (grams ib cubic centimeter) lossis kg / m³ (kilograms ib cubic meter). Rau cov neeg ua haujlwm hauv kev lag luam tshuaj, cov ntaub ntawv meej ntawm qhov ntom ntom ntawm ethyl acetate tuaj yeem pab suav cov khoom siv kom raug, txhim kho cov txheej txheem thiab ua kom cov khoom zoo.
Cov nqi tshwj xeeb rau qhov ntom ntawm ethyl acetate
Raws li tus qauv (20 ° C, 1 cua), qhov ceev ntawm ethyl acetate yog kwv yees li 0.902 g / cm³. Tus nqi no txhais tau hais tias txhua qhov cubic centimeter ntawm ethyl acetate hnyav kwv yees li 0.902 grams. Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov ceev sib txawv nrog qhov kub thiab txias. Raws li qhov kub thiab txias, qhov ntim ntawm cov kua feem ntau nthuav, ua rau qis dua. Yog li ntawd, qhov tshwm sim ntawm qhov kub thiab txias hloov ntawm qhov chaw ua haujlwm ntawm qhov ntom ntawm ethyl acetate yuav tsum raug coj mus rau hauv tus account thaum ua cov kev suav raug.
Cov yam ntxwv cuam tshuam rau qhov ntom ntawm ethyl acetate
Kub: Kub yog ib qho tseem ceeb cuam tshuam rau qhov ntom ntawm ethyl acetate. Raws li qhov kub thiab txias nce, cov molecular motion ntawm cov kua intensifies thiab lub ntim nce, uas ua rau ib tug txo nyob rau hauv ceev. Feem ntau hauv kev tsim khoom, qhov ceev ntawm ethyl acetate raug kho raws li qhov kub thiab txias hloov kom ntseeg tau qhov tseeb ntawm kev ntsuas.

Purity: Qhov ntom ntawm ethyl acetate kuj cuam tshuam los ntawm nws cov purity. Yog hais tias ethyl acetate tov nrog lwm yam impurities, xws li dej los yog lwm yam kuab tshuaj, qhov ceev yuav hloov. Yog li ntawd, kev siv siab purity ethyl acetate tsis tsuas yog ua kom cov txheej txheem ruaj khov, tab sis kuj ua rau cov ntaub ntawv muaj kev ruaj ntseg ntau dua.

Siab: Txawm hais tias lub siab muaj qhov cuam tshuam me me rau qhov ntom ntawm cov kua, nyob rau hauv cov xwm txheej siab, qhov ceev yuav nce me ntsis. Qhov no yuav tsum tau coj mus rau hauv tus account nyob rau hauv high-pressure industrial daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv high precision kev ua hauj lwm koom nrog.

Kev siv tswv yim ntawm ethyl acetate ntom ntom
Hauv kev lag luam tshuaj, qhov ntom ntawm ethyl acetate muaj cov ntawv thov tseem ceeb hauv ntau qhov chaw. Hauv kev tsim cov khoom xws li coatings thiab adhesives, cov ntaub ntawv ceev yog lub hauv paus rau kev txiav txim siab qhov sib npaug ntawm cov khoom. Hauv kev khaws cia thiab thauj cov txheej txheem, cov ntaub ntawv ceev yuav pab suav cov ntim ntim thiab thauj cov nqi ntawm cov khoom. Hauv cov txheej txheem sib cais xws li distillation, qhov ntom ntom yog qhov tseem ceeb rau kev txiav txim siab qhov ua tau zoo ntawm kev sib cais ntawm cov khoom sib xws.

Kev nkag siab txog qhov ntom ntom ntawm ethyl acetate thiab cov yam ntxwv cuam tshuam rau nws yog qhov tseem ceeb rau txhua yam ntawm kev tsim tshuaj. Los ntawm kev tuav cov teebmeem ntawm qhov kub thiab txias, purity thiab siab ntawm qhov ntom ntawm ethyl acetate, cov kws kho mob tuaj yeem tswj cov txheej txheem ntau lawm thiab txhim kho cov khoom zoo. Peb cia siab tias tsab xov xwm no yuav pab koj kom nkag siab zoo dua thiab siv lub cev tseem ceeb ntawm qhov ntom ntom ntawm ethyl acetate hauv kev siv tswv yim.
