Qhov ntom ntawm n-butanol: kev tsom xam qhov tob thiab nws cov yam ntxwv cuam tshuam
Qhov ntom ntawm n-butanol yog ib qho tseem ceeb ntawm lub cev tsis zoo hauv kev tsim tshuaj lom neeg, uas muaj kev cuam tshuam ncaj qha rau cov khoom lag luam tswj, kev ua kom zoo dua qub thiab kev tswj hwm kev nyab xeeb. Daim ntawv no yuav tshuaj xyuas kom meej txog cov yam ntxwv ntawm n-butanol, qhov cuam tshuam ntawm qhov ceev thiab nws qhov tseem ceeb hauv kev siv tswv yim.
Cov khoom tseem ceeb thiab qhov ceev ntawm n-butanol
n-Butanol (1-butanol) yog cov kua tsis muaj xim, pob tshab nrog cov ntxhiab tsw ntxhiab, uas yog siv dav hauv cov xim, plastics, detergents thiab tshuaj. Cov tshuaj formula ntawm n-butanol yog C₄H₉OH thiab nws belongs rau cov pab pawg neeg ntawm thawj cawv. Qhov ntom ntawm n-butanol yog qhov loj ntawm cov khoom hauv ib chav tsev ntim, uas feem ntau qhia hauv grams ib cubic centimeter (g / cm³) lossis kilograms ib cubic meter (kg / m³). Hauv lub xeev tus qauv (20 ° C, 1 atm), qhov ceev ntawm n-butanol yog kwv yees li 0.81 g / cm³.
Cov yam ntxwv cuam tshuam qhov ntom ntawm n-butanol
Tus nqi ntawm n-butanol ntom ntom tsis zoo li qub thiab cuam tshuam los ntawm ntau yam. Qhov kub thiab txias yog ib qho ntawm cov khoom tseem ceeb cuam tshuam rau qhov ntom ntom. Raws li qhov kub thiab txias, lub thermal txav ntawm n-butanol molecules yog txhim khu kev qha thiab qhov sib nrug ntawm cov molecules nce, ua rau lub ntim expansion thiab txo qhov ntom. Ntawm qhov tsis sib xws, ntawm qhov kub thiab txias, qhov kev txav ntawm molecular tsis muaj zog thiab qhov ceev nce ntxiv. Kev sim cov ntaub ntawv qhia tias qhov ceev ntawm n-butanol txo qis li ntawm 0.005 g / cm³ rau txhua 10 ° C nce hauv qhov kub thiab txias.
Lub siab kuj yog ib qho tseem ceeb ntawm qhov ntom ntawm n-butanol, txawm tias nws cov nyhuv me me. Nyob rau hauv kev kub siab, qhov sib txawv molecular yog compressed thiab qhov ceev ntawm n-butanol nce me ntsis. Cov cuab yeej no tseem ceeb tshwj xeeb hauv cov tshuab hluav taws xob siab thiab yuav tsum tau tswj xyuas kom tsis txhob muaj qhov yuam kev.
Purity thiab cov xwm txheej ntawm qhov sib tov kuj tuaj yeem cuam tshuam qhov ntom ntawm n-butanol. Thaum n-butanol ntawm purity siab dua muaj qhov ruaj khov, nyob rau hauv cov ntawv thov kev lag luam feem ntau yuav tsum sib xyaw n-butanol nrog rau lwm cov kuab tshuaj, thiab qhov ceev yuav txawv nyob ntawm qhov sib piv ntawm cov sib tov. Yog li ntawd, qhov tseeb ntsuas thiab tswj qhov ceev ntawm n-butanol yog qhov tseem ceeb rau kev ua kom zoo ntawm cov txheej txheem ntau lawm.
Qhov tseem ceeb ntawm n-butanol ceev hauv kev siv tswv yim
Kev nkag siab thiab tswj qhov ceev ntawm n-butanol yog qhov tseem ceeb tshaj plaws hauv kev tsim tshuaj. Qhov ntom ntawm n-butanol tuaj yeem siv los ua qhov ntsuas tseem ceeb rau kev tswj kom zoo. Hauv cov txheej txheem tsim khoom, los ntawm kev saib xyuas qhov kev hloov ntawm qhov ntom ntom, qhov purity ntawm raw cov ntaub ntawv thiab kev ruaj ntseg ntawm cov txheej txheem tshuaj tiv thaiv tuaj yeem txiav txim tau zoo.
Cov ntaub ntawv ceev yog ib qho kev qhia rau txheej txheem tsim thiab optimisation. Piv txwv li, nyob rau hauv tus txheej txheem ntawm huab hwm coj thiab tshav kub hloov, qhov ceev ntawm n-butanol cuam tshuam lub fluidity thiab loj hloov efficiency, uas nyob rau hauv lem cuam tshuam rau lub reactor tsim thiab lub zog noj. Yog li ntawd, nyob rau hauv tus txheej txheem tsim theem, kev hloov txoj cai ntawm n-butanol ceev yuav tsum tau tag nrho txiav txim siab nyob rau hauv thiaj li yuav maximize ntau lawm efficiency.
Qhov ceev ntawm n-butanol kuj tseem cuam tshuam nrog kev tsim khoom nyab xeeb. Nyob rau hauv cov txheej txheem ntawm kev cia thiab thauj, kev hloov ntawm qhov ceev yuav cuam tshuam rau lub ntim ntawm cov kua, uas nyob rau hauv lem cuam tshuam rau kev xaiv ntawm ntim ntim thiab kev nyab xeeb ntawm cov txheej txheem thauj. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntawm qhov sib txawv ntawm qhov kub thiab txias, qhov kev hloov ceev yog pom tseeb dua, yuav tsum tau them nyiaj tshwj xeeb.
Cov ntsiab lus
Kev nkag siab thiab tswj qhov ceev ntawm n-butanol yog ib qho tseem ceeb ntawm kev tsim tshuaj. Los ntawm kev txheeb xyuas qhov cuam tshuam ntawm qhov kub thiab txias, siab, purity thiab sib xyaw ua ke ntawm qhov ntom ntawm n-butanol, peb tuaj yeem ua kom zoo dua cov txheej txheem ntau lawm, txhim kho cov khoom zoo thiab ua kom muaj kev nyab xeeb. Yog li ntawd, hauv kev xyaum, kev soj ntsuam tas li thiab kev tswj hwm ntawm n-butanol ntom ntom yog tsim nyog los xyuas kom meej cov txheej txheem du.
