Raw Khoom Siv Tshuaj Xylene

Xylene yog cov kua tsis muaj xim, pob tshab thiab muaj ntxhiab tsw. Nws yog cov khoom ntawm kev hloov ntawm ob lub hydrogen atoms ntawm lub nplhaib benzene los ntawm pawg methyl. Nws qhov kub kub yog 137-140 ºC. Xylene tuaj yeem muab faib ua peb isomers: o-xylene, m-xylene thiab p-xylene raws li qhov sib txawv ntawm ob pawg methyl. Hauv kev lag luam, xylene hais txog kev sib xyaw ntawm cov isomers saum toj no thiab ethyl benzene. Feem ntau, qib ntawm cov dej huv huv yog qib siab dua thiab qib thawj cov khoom lag luam nrog cov dej distillation ntawm 3 ºC thiab 5 ºC.

Khoom Description

Xylene yog cov kua tsis muaj xim, pob tshab thiab muaj ntxhiab tsw. Nws yog cov khoom ntawm kev hloov ntawm ob lub hydrogen atoms ntawm

benzene nplhaib los ntawm methyl pawg. Nws qhov kub kub yog 137-140 ºC. Xylene tuaj yeem muab faib ua peb isomers: o-xylene,

m-xylene thiab p-xylene raws li txoj haujlwm sib txawv ntawm ob pawg methyl. Hauv kev lag luam, xylene hais txog cov

Kev sib xyaw ntawm cov isomers saum toj no thiab ethyl benzene. Feem ntau, qib ntawm cov dej huv huv yog qib siab dua thiab qib thawj cov khoom lag luam nrog cov dej distillation ntawm 3 ºC thiab 5 ºC. Nws tuaj yeem sib xyaw nrog ethanol, chloroform lossis ether ntawm qhov xav tau thiab insoluble hauv dej. Nws yog dav siv nyob rau hauv cov organic solvents, tshuaj hluavtaws, coatings, resins, dyes thiab tshuaj tua kab. yog cov kua tsis muaj xim, pob tshab thiab muaj ntxhiab tsw.
