Izina RY'IGICURUZWA:Toluene

Imiterere ya molekulari ：C7H8

CAS Oya ：108-88-3

Ibicuruzwa bya molekuline structure

Ibikoresho bya Shimi:：

Toluene, ifumbire mvaruganda hamwe na formula ya chimique C₇H₈, ni amazi atagira ibara, ahindagurika hamwe numunuko wihariye wimpumuro nziza.Ifite umutungo ukomeye.Ntibishobora gukoreshwa na Ethanol, ether, acetone, chloroform, karubone disulfide na acide glacial acetike, kandi bigashonga cyane mumazi.Umuriro, imyuka irashobora gukora imvange iturika hamwe numwuka, ubwinshi bwuruvange rwuruvange rushobora guturika murwego ruto.Uburozi buke, LD50 (imbeba, umunwa) 5000mg / kg.ubwinshi bwa gaze nibiyobyabwenge, birakaze

Gusaba ：

Toluene ikomoka kumatara yamakara kimwe na aspetrole.Bibaho muri lisansi hamwe na peteroli nyinshi.Toluene ikoreshwa mu gukora prodetrinitrotoluene (TNT), toluene diisocyanate, na benzene;nkibikoresho bya fordyes, ibiyobyabwenge, hamwe nogukoresha ibikoresho;kandi nkinganda zinganda za reberi, amarangi, impuzu, nubutaka.

Toluene ifite porogaramu nyinshi mu nganda z’imiti n’ibikomoka kuri peteroli, hafi toni miliyoni 6 zikoreshwa buri mwaka muri Amerika na toni miliyoni 16 zikoreshwa ku isi.Ikoreshwa ryinshi rya toluene ninkindi ya octane muri lisansi.Toluene ifite igipimo cya octane kingana na 114. Toluene ni kimwe mu bintu bine byingenzi bihumura neza, hamwe na benzene, xylene, na Ethylbenzene, bikozwe mu gihe cyo gutunganya kugira ngo bongere imikorere ya lisansi.Hamwe na hamwe, ibyo bice bine bigufi muri make nka BTEX.BTEX nigice kinini cya lisansi, ikora hafi 18% kuburemere bwuruvange rusanzwe.Nubwo igipimo cya aromatics kiratandukanye kugirango gitange imvange zitandukanye kugirango zuzuze imiterere yimiterere nigihe cyigihe, toluene nikimwe mubice byingenzi.Benzin isanzwe irimo toluene hafi 5% kuburemere.
Toluene ni ibiryo by'ibanze bikoreshwa mu gukora ibinyabuzima bitandukanye.Ikoreshwa mukubyara diisocyanates.Isocyanates ikubiyemo itsinda rikora? N = C = O, na diisocyanates irimo bibiri muribi.Diisocyanate ebyiri nyamukuru ni toluene 2,4-diisocyanate natoluene 2,6-diisocyanate.Umusaruro wa diisocyanate muri Amerika ya ruguru ugera hafi kuri miliyari buri mwaka.Kurenga 90% byumusaruro wa toluene diisocyanate ukoreshwa mugukora ifuro rya polyurethanes.Iyanyuma ikoreshwa nkibintu byoroshye byuzuza ibikoresho, uburiri, hamwe nudushumi.Mu buryo bukomeye ikoreshwa mugukingira, gutwikisha ibishishwa bikomeye, ibikoresho byubaka, ibice byimodoka, hamwe na skroline ya skate.

Mugukora acide benzoic, benzaldehyde, ibisasu, amarangi, nibindi byinshi bivanga kama;nk'umuti wo gusiga amarangi, lacquers, amenyo, resin;kunanuka kuri wino, parufe, amarangi;mu gukuramo amahame atandukanye mu bimera;nk'inyongera ya lisansi.
