Methanol ntom: Kev Tshawb Xyuas Tshaj Tawm thiab Kev Tso Cai Tso Cai
Methanol, raws li cov organic tseem ceeb, muaj ntau cov ntawv thov hauv kev lag luam tshuaj. To taub cov khoom siv lub cev ntawm methanol, xws li qhov ceev ntawm methanol, yog qhov tseem ceeb rau kev tsim cov tshuaj, chaw cia khoom thiab thauj khoom. Hauv tsab xov xwm no, peb yuav tham txog cov ntsiab lus ntawm Methanol ntom, nws qhov cuam tshuam thiab nws qhov tseem ceeb hauv kev siv.
Lub tswv yim ntawm methanol ntom
Qhov ceev ntawm methanol yog qhov loj ntawm Methanol ib lub ntim ntim, feem ntau qhia nyob rau hauv grams ib cubic centimeter (g / cmo meter ib cubic meter (kg / mp / mp / mp / mp / mp / mp / mp / mp / mg / mp / mp / mg / mg / mg / mg / mp / mg / mg / mg / mg / mg / mg / mg / mg / mg / mg / hlet). Nyob rau hauv cov qauv ntawm cov qauv, qhov ceev ntawm methanol ntawm 20 ° C yog kwv yees li 0.7918 g / cm³. Qhov ceev no tus nqi ua rau methanol sib dua dua li dej (uas muaj qhov ntom ntom (uas muaj qhov ntom ntom ntawm li 1 g / cm³), uas nyob rau hauv ntau daim ntawv thov txhais tau tias sib txawv ntawm cov khoom sib txawv thiab kev cia khoom sib txawv.
Yam cuam tshuam rau qhov ntom ntom ntawm methanol
Cawv ntawm qhov kub
Qhov kub yog ib qho ntawm qhov tseem ceeb cuam tshuam rau qhov ceev ntawm methanol. Raws li qhov kub nce ntxiv, cov lus tsa suab molecular ntawm methanol nce, lub ntim nthuav dav thiab qhov ntom txo qis. Hloov siab, thaum qhov ntsuas kub, txo cov molecular txav qeeb qeeb thiab qhov ceev ntawm methanol nce. Yog li ntawd, hauv kev xyaum, tuam txhab chemical feem ntau kho cov qauv tsim thiab muaj peev xwm ntawm cov khoom khaws cia raws li qhov kub thiab txias.
Cuam tshuam ntawm kev coj dawb huv
Lub purity ntawm methanol kuj cuam tshuam ncaj qha rau nws qhov ntom ntom. Hauv kev lag luam ntau lawm, methanol tuaj yeem sib xyaw nrog cov dej los yog lwm yam kev tsis txaus siab, uas feem ntau yog kev hloov pauv ntawm methanol, yog li hloov tag nrho cov ceev ntawm methanol. Yog li ntawd, tswj txoj kev coj dawb huv ntawm methanol yog qhov tseem ceeb hauv kev siv cov xwm txheej tsis sib xws.
Daim Ntawv Thov Kev Ua Yeeb Yam rau Methanol ntom
Cov Ntawv Thov Siv Tshuaj Lom Neeg
Cov ntaub ntawv raug ntawm Methanol ntom yog qhov tseem ceeb rau kev txhaj tshuaj thiab cov tshuaj tiv thaiv kev tswj ntawm kev tsim cov tshuaj. Ntau cov tshuaj lom zem muaj txoj kev yuav tsum tau ua rau cov concentration ntawm reactration ntawm reactants, uas feem ntau txiav txim siab los ntawm kev ntom. Piv txwv li, hauv ib qho kev ntsuas methanol-rau-formaldehyde, qhov tseeb ceev ntsuas ntsuas kev ua kom tau cov tshuaj tiv thaiv thiab kev ua kom huv ntawm cov khoom lag luam.
Cov ntawv thov hauv kev khaws cia thiab thauj
Methanol ntom cuam tshuam cov qauv ntawm kev tso tsheb hlau luam thiab cov thawv thauj khoom. Thaum lub sijhawm thauj, qis ntom ntom txhais tau tias methanol nyhav tsawg dua rau tib lub ntim, uas tuaj yeem txo cov nqi thauj. To taub txog cov methanol kuj tseem pab kom ua kom tau zoo rau cov qauv tsim ntawm cov khoom siv cia kom ntseeg tau tias kev ceev thiab tiv thaiv kom tsis txhob muaj kev xau.
Hauv cov ntsiab lus
Qhov ceev ntawm methanol tsis yog tsuas yog ib qho yooj yim ntawm lub cev, tab sis nws kuj tseem yog qhov tseem ceeb rau kev siv tshuaj lom neeg, chaw cia khoom thiab thauj khoom thiab thauj khoom. Nkag siab thiab kho kom raug cov ntaub ntawv methanol tsis yog siv cov nqi ntau lawm, tab sis kuj tseem siv tau kev nyab xeeb zoo thiab ua kom muaj kev nyab xeeb zoo. Txog cov kws kho mob tshuaj, kev paub txog methanol ntom yog ib feem tseem ceeb ntawm lawv cov kev txawj tshaj lij.
