Chemical Properties::

Toluene, organic compound ine kemikari formula C₇H₈, imvura isina ruvara, isingachinjiki uye ine hwema hunonhuhwirira. Iine simba refractive pfuma. Inosanganiswa ne ethanol, ether, acetone, chloroform, kabhoni disulfide uye glacial acetic acid, uye yakanyanya kunyungudika mumvura. Inopisa, iyo mhute inogona kuumba musanganiswa unoputika nemhepo, huwandu hwehuwandu hwemusanganiswa hunogona kuputika panzvimbo yakaderera. Low toxicity, LD50 (gonzo, nemuromo) 5000mg/kg. kukwirira kwegasi kunodhaka, kunogumbura

Application:

Toluene inotorwa kubva mumarasha tara pamwe neaspetroleum. Inowanikwa mu peturu uye many petroleum solvents. Toluene inoshandiswa kugadzira trinitrotoluene (TNT), toluene diisocyanate, uye benzene; sechinhu chekugadzira dhayi, zvinodhaka, uye zvekugezesa; uye sechinhu chinonyungudutsa mumaindasitiri chemarabha, pendi, marashi, uye oiri.

Toluene ine akawanda maapplication muindasitiri yemakemikari nepetroleum, ine matani angangoita 6 miriyoni anoshandiswa pagore muUnited States uye 16 miriyoni matani anoshandiswa pasi rose. Iko kushandiswa kukuru kwetoluene kwakafanana neoctane booster mupeturu. Toluene ine muyero weoctane we114. Toluene chimwe chezvikamu zvina zvakakosha zvinonhuhwirira, pamwe nebenzene, xylene, uye ethylbenzene, zvinogadzirwa pakunatswa kuti peturu ishande zvakanaka. Pamwe chete, makomisheni mana aya akadimburirwa seBTEX. BTEX chikamu chikuru chepeturu, ichiita 18% nehuremu hwemusanganiswa wakajairika. Kunyangwe iwo chikamu chearomatics chakasiyana-siyana kugadzira masanganiswa akasiyana kuti asangane nenzvimbo nemwaka zvinodikanwa, toluene chimwe chezvinhu zvikuru. A yakajairika peturu ine inenge 5% toluene nehuremu.
Toluene ndiyo yekutanga feedstock inoshandiswa kugadzira akasiyana organic makomisheni. Inoshandiswa kugadzira diisocyanates. Isocyanates ine boka rinoshanda ?N = C = O, uye diisocyanates ine zviviri zveizvi. Iwo maviri makuru diisocyanates ari toluene 2,4-disocyanate uyetoluene 2,6-disocyanate. Kugadzirwa kwe diisocyanates muNorth America kuri pedyo nebhiriyoni pagore. Zvinopfuura 90% ye toluene diisocyanate kugadzirwa inoshandiswa kugadzira polyurethanes furo. Iwo ekupedzisira anoshandiswa seanochinjika kuzadza fenicha, yekurara, uye makushion.Mu fomu yakaoma inoshandiswa kuvharisa, magomba akaomarara, zvekuvaka, auto parts, androller skate mavhiri.

Mukugadzira benzoic acid, benzaldehyde, zvinoputika, madhayi, uye mamwe akawanda organic Compounds; semugadziri wependi, lacquers, gums, resins; kutetepa ingi, pefiyumu, madhayi; mukutorwa kwemitemo yakasiyana-siyana kubva mumiti; sekuwedzera peturu.
