Cov ncauj lus kom ntxaws ntawm cov boiling taw tes ntawm Toluene
Toluene yog cov organic sib txuas nrog ntau cov ntawv thov hauv kev lag luam tshuaj. To taub cov khoom siv lub cev ntawm Toluene, tshwj xeeb tshaj yog nws qhov cub npau npau, yog qhov tseem ceeb rau kev tsim thiab ua haujlwm ntawm cov txheej txheem ntau lawm. Hauv tsab xov xwm no, peb yuav tshawb txog qhov kev paub ntawm lub qhov cub npau npau thiab txheeb xyuas nws qhov tseem ceeb hauv kev lag luam thiab qhov cuam tshuam rau nws.
Cov Khoom Yooj Yim ntawm Toluene thiab nws qhov cub npau npau
Toluene (Toluene) yog methyl hloov ntawm benzene, nrog tshuaj rau cov mis nyuj c7h8. Nws yog cov kua tsis muaj kob nrog cov ntxhiab tsw ntxhiab tsw ntxhiab. Toluene muaj qhov cub kub npau suav txog 110.6 ° C (231.1 ° F), uas yog qhov ntsuas kub nws hloov los ntawm cov kua rau roj. Qhov cub sov ntawm toluene yog qhov tseem ceeb hauv kev siv cov ntawv thov vim nws cuam tshuam nrog distillation, sib cais, thiab lwm yam kev hloov tshuaj lom neeg nrog rau theem hloov pauv.
Toluene boiling taw tes hauv kev siv cov ntawv thov
Toluene siv feem ntau yog siv los ua cov kuab tshuaj, cov khoom siv tsis zoo, thiab nruab nrab hauv cov khoom siv hluav taws xob hauv pettrochemical thiab organic synthesis. Toluene muaj me ntsis kub dua boiling taw tes dua benzene, yog li lwm cov tebchaw sib xyaw ua ke tau yooj yim los ntawm kev ntsuas kub thaum sib tov. Qhov no yog qhov tseem ceeb rau kev tsim cov khoom lag luam nrog cov kev xav tau siab. Lub qhov cub npau npau ntawm toluene kuj tseem ua lub luag haujlwm ntawm kev txhim kho hluav taws xob siv hauv cov txheej txheem kev lag luam. Piv txwv li, thaum lub sij hawm distillation, paub txog qhov boiling point ntawm toluene tuaj yeem pab txiav txim siab cov qauv cov khoom cua sov, yog li txo cov nqi hluav taws xob cua sov.
Yam cuam tshuam rau txoj kev npau npau ntawm toluene
Txawm hais tias Toluene muaj cov qauv rhaub ntawm 110.6 ° C, hauv kev xyaum, hauv kev xyaum, hloov hauv qhov kev hloov siab hauv qhov cub hauv qhov cub. Hauv qhov chaw qis qis, qhov cub kub ntawm Toluene txo qis, thaum nyob hauv ib puag ncig muaj txiaj ntsig, lub boiling point nce. Yog li ntawd, cov nyhuv ntawm lub siab rau ntawm boiling point yuav tsum raug txiav txim siab thaum tsim thiab ua haujlwm los ntawm toluene. Qhov kub npau suav ntawm toluene kuj hloov pauv thaum nws sib xyaw, tshwj xeeb yog tsim, uas yuav muaj cov ntsiab lus npau npau uas muaj los ntawm cov toluene ntshiab.
Toluene boiling taw tes thiab nyab xeeb tuav
Hauv kev lag luam kev lag luam koom nrog TOLUES, paub thiab nkag siab thiab nkag siab txog qhov taw tes npau npau yog qhov tseem ceeb rau kev nyab xeeb. Raws li Toluene yog cov kua hluav taws kub ua kua, thaum muaj qhov kub tshaj nws txoj kev npau npau npau, cov vapor tsim tawm, uas nyeg muaj kev pheej hmoo ntawm kev tawg thiab hluav taws. Yog li ntawd, thaum tuav toluene, qhov ntsuas kub yuav tsum tau nruj thiab cov kev ntsuas hluav taws thiab cov kev ntsuas hluav taws tawg thiab cov khoom tiv thaiv tawg.

Qhov cub kub ntawm Toluene yog qhov tseem ceeb ntawm lub cev tsis muaj peev xwm tsis tuaj yeem ua rau muaj kev lag luam tsim tshuaj, uas tsis yog cuam tshuam rau kev muaj kev nyab xeeb. Los ntawm kev nkag siab tob ntawm lub boiling taw tes ntawm toluene thiab nws cov txheej txheem tshuaj lom neeg tuaj yeem tsim tau zoo dua los txhim kho cov khoom lag luam zoo thiab tsim kev nyab xeeb. Hauv kev coj ua, kev tswj hwm ntawm lub qhov cub npau npau ntawm kev ua ke nrog cov siab, sib xyaw ua ke thiab lwm yam txheej txheem sib txawv.
