Iipropathi zeekhemikhali::

I-Touluene, i-organic ye-organic yefomula c₇hu₈, ngulwelo olungenabala, oluguqukayo nge-odor evuthayo. Inepropathi eqinileyo eyomeleleyo. Kuyaqondakala i-ethanol, i-ether, i-acetone, i-chloroform, i-carbon discofe decicrefic kunye ne-glaciciclic acid, kwaye inyibilike kakhulu emanzini. Ukutshaya, umphunga unokwenza umxube wokuqhushumba unomoya, ukugxininiswa komthamo womxube kunokuqhuma kwinqanaba eliphantsi. Ityhefu esezantsi, ld50 (i-rat, ngomlomo) 5000mg / kg. Uxinzelelo oluphezulu lwerhasi luyi-narcotic, luyacaphukisa

Isicelo:

I-Touluene isuselwa kwi-Coal tat kunye ne-activetroleum. Yenzeka kwi-petroli kunye ne-hardpettroleum. I-Touluene isetyenziselwa ukuvelisa i-PRETTRINITFROTOME (i-TNT), i-toluene diisocyanciate, kunye ne-Bezene; Njengamathako esithako, iziyobisi, kunye neziqwengana; Kwaye njengomzi wezolimo kwiirubber, iipeyinti, iingubo, i-andoils.

I-toulue inezicelo ezininzi kumzi-mveliso wekhemikhali kunye nepetroleum, malunga neetoni ezi-6 ezisetyenziswa minyaka le e-United States kunye neetoni eziyi-16 ezisetyenziswa kwihlabathi liphela. Ukusetyenziswa okukhulu kwe-toluene kuyinto enyusa i-octane infolline. I-Touluene inomlinganiso we-octane ye-octane ye-114. I-toluene yenye yezona zinto zine ziyinqamlezo, kunye ne-Benzene, i-Bezene, kunye ne-Ethylbenzene, eziveliswa ngexesha lokuphucula ukusebenza kwe-petroli. Ngokudibeneyo, ezi ziqokelelo ezine zincitshisiwe njenge-BTEX. I-BTEX yeyona nto iphambili kwi-petroli, yakha malunga ne-18% ngobunzima bendlela eqhelekileyo yokudibanisa. Nangona uninzi lwenani le-allomatics lungafani nokuvelisa iinkqubo ezahlukeneyo zokudibana neemfuno zeJografi kunye neemfuno zexesha, i-toluene yenye yezinto eziphambili. Ipetroli eqhelekileyo iqulethe malunga ne-5% i-toluene ngesiqhelo.
I-Touluene yiyona nto iphambili esetyenziselwa ukuvelisa imigangatho eyahlukeneyo yezinto eziphilayo. I-Shoreto ivelise i-viocytans. I-Isoclonates iqulethe iqela elisebenzayo? N = c = o, kunye ne-diisocynatesstatescontathu mabini kwezi. Ezi zinto zimbini ziphambili ze-disoclonites ze-2,4-disocyanate andtofaene 2,6-disocyanate. Ukuveliswa kwe-diisocysates eMntla Merika ikufuphi neebhiliyoni qho ngonyaka. Ngaphezulu kwe-90% yemveliso ye-Issugene Dialocyanate isetyenziselwa ukulungiselela i-fespolythanes. Oku kusetyenziswayo kusetyenziswa njengokugcwalisa ifanitshala, ukulala, kunye nama-sushion.in ifomu ye-rigid isetyenziselwa ukufakelwa, iingubo ezinzima zegobolo, iinxalenye zokwakha, ii-androller skiviels.

Ukuqulunqwa kwe-Benzoic Acid, MBeldehyde, iziqhushumbisi, idayi, kunye nezinye izinto eziphilayo ezininzi; Njengomsele weepeyinti, izilafu, iintsini, i-resins; Umncinci wee-inks, iziqholo, idaya; ekukhokeleni imigaqo eyahlukeneyo evela kwizityalo; njenge-petroli irenki.
