Tshuaj Tshuaj Muaj Zog::

Toluene, ib cov organic sib xyaw nrog cov tshuaj mis nyuj c₇h₈, yog cov kua tsis muaj xim, tsis muaj kua nrog lub txiv tsw ntxhiab tsw. Nws muaj cov khoom muaj zog tshiab. Nws yog me ntsis nrog ethanol, ether, acetone, chloroform, carbon rockor thiab glacial acetic acid, thiab me ntsis soluble hauv dej. Nqaij, lub vapor tuaj yeem tsim cov cua sib xyaw nrog huab cua, cov ntim kev sib xyaw kom sib xyaw tuaj yeem tawg ntawm qhov tsawg. Tsawg toxicity, LD50 (RAT, qhov ncauj) 5000mg / kg. Cov pa roj ntau ntawm cov roj yog cov narcotic, khaus

Daim Ntawv Thov:

Toluene yog muab tau los ntawm cov tawv nqaij ua kom zoo li zoo aspetroum. Nws tshwm sim hauv roj av thiab txiv neej matypetoleum cov kuab tshuaj. Toluene yog siv los tsim cov chaw muag khoom (tnt), tolrene diisocyanate, thiab benzene; raws li ib qho khoom xyaw rau cov tshuaj muaj yees, yeeb tshuaj, thiab dej paug; Thiab raws li kev muaj kev lag luam rau rubbers, cov xim tha xim, tsho xim, thiab nyiaj.

Toluene muaj ntau cov kev thov hauv kev lag luam thiab kev lag luam roj av, nrog kwv yees li 6 lab tons siv ib xyoos ib zaug hauv Tebchaws Meskas thiab 16 lab nqa khoom siv thoob ntiaj teb. Kev siv loj ntawm toluene yog ua lub roj oxolane hauv roj av. Toluene muaj ib lub octane ntaus nqi ntawm 114. Toluene yog ib ntawm plaub tus thawj xib fwb, thiab kev ua kom zoo nkauj, thiab ua kom muaj kev ua kom zoo rau kev txhim kho cov roj av ua haujlwm. Suav ua ke, cov plaub sib txuas no yog cov lus luv li BTEX. BTEX yog qhov tiv thaiv loj ntawm cov roj av, sib sau txog 18% los ntawm qhov hnyav ntawm ib qho kev sib xyaw. Txawm hais tias qhov kev faib ua feem ntawm cov neeg muaj kuab muaj ntau yam los tsim kev sib txawv los ua kom tau raws li thaj chaw thiab cov raws caij nyoog, tolreal yog ib qho ntawm cov khoom loj. Ib qho roj av nyias muaj kwv yees li 5% toluene los ntawm qhov hnyav.
Toluene yog thawj pub dawb siv los tsim ntau cov organic sib txuas. Nws yog siv rau tsim diisocyanates. Isocyanates muaj pab pawg ua haujlwm? N = c = O, thiab Diisocyanatalescontainion ob ntawm cov no. Ob lub luag hauj lwm tseem ceeb yog toluene 2,4-diisocyanate Andtoluene 2,6-Diisocyanate. Zeem ntawm Diisocyanates nyob rau hauv North America nyob ze rau ntawm billionpounds txhua xyoo. Ntau tshaj 90% ntawm Toluene Diisocyanate ntau lawm yog siv rau cov ua npuas ncauj. Lub tom kawg tau siv los hloov chaw nyob rau rooj tog, txaj, thiab Cushions.in Cov ntaub ntawv tawv, cov khoom siv pib, thiab cov log tsheb thauj khoom plig.

Hauv kev tsim cov khoom lag luam benzoic, benzaldehyde, tawg, dyes, thiab ntau lwm cov ocegic tebchaw; Raws li cov kuab tshuaj rau cov xim tha xim, lacquers, pos hniav, covsins; thinner rau inks, naj hoom, dyes; nyob rau hauv extraction ntawm ntau cov ntsiab cai los ntawm cov nroj tsuag; raws li roj av ntxiv.
