Njirimara kemịkalụ::

Toluene, ngwakọta organic nwere usoro kemịkal C₇H₈, bụ mmiri na-enweghị agba, nke na-agbanwe agbanwe nke nwere isi ísì ụtọ. O nwere ihe ntughari siri ike. Ọ na-esighi ike na ethanol, ether, acetone, chloroform, carbon disulfide na glacial acetic acid, yana obere soluble na mmiri. Na-enwu ọkụ, vapor nwere ike ịmepụta ngwakọta ihe mgbawa na ikuku, ụda olu nke ngwakọta nwere ike ịgbawa na obere ala. Nsi dị ala, LD50 (oke, ọnụ) 5000mg/kg. nnukwu mkpokọta gas bụ ọgwụ ọjọọ, na-akpasu iwe

Ngwa:

A na-enweta Toluene site na coal tar yana aspetroleum. Ọ na-apụta na mmanụ ụgbọala na ọtụtụ ihe mgbaze mmanụ ala. A na-eji Toluene emepụta trinitrotoluene (TNT), toluene diisocyanate, na benzene; dị ka ihe mgwa fordyes, ọgwụ ọjọọ, na ncha; na dị ka ihe mgbaze maka rubbers, agba, mkpuchi na mmanụ.

Toluene nwere ọtụtụ ngwa na ụlọ ọrụ kemịkalụ na mmanụ ala, yana ihe dị ka nde tọn 6 na-eji kwa afọ na United States yana nde tọn 16 na-eji ụwa niile. Isi ojiji nke toluene bụ dị ka octane booster na mmanụ ụgbọala. Toluene nwere ogo octane nke 114. Toluene bụ otu n'ime ogige aromatic anọ bụ isi, yana benzene, xylene, na ethylbenzene, nke a na-emepụta n'oge a na-emezigharị iji kwalite ọrụ mmanụ ụgbọala. N'ịchịkọta, a na-akpọkọta ogige anọ ndị a dị ka BTEX. BTEX bụ akụkụ bụ isi nke mmanụ ụgbọala, na-eme ihe dịka 18% n'ịdị arọ nke ngwakọta a na-ahụkarị. Ọ bụ ezie na ọnụ ọgụgụ nke aromatics dịgasị iche iche iji mepụta ngwakọta dị iche iche iji gboo ihe gbasara mpaghara na oge oge, toluene bụ otu n'ime ihe ndị bụ isi. Otu mmanụ ụgbọala nwere ihe dị ka 5% toluene site n'ịdị arọ.
Toluene bụ nri nri bụ isi eji emepụta ogige organic dị iche iche. A na-eji ya emepụta diisocyanates. Isocyanates nwere otu ọrụ ?N = C = O, na diisocyanates nwere abụọ n'ime ndị a. Isi diisocyanates abụọ bụ toluene 2,4-diisocyanate na toluene 2,6-diisocyanate. Mmepụta diisocyanates na North America dị nso otu ijeri paụnd kwa afọ. A na-eji ihe karịrị 90% nke mmepụta toluene diisocyanate eme ka ọ bụrụ ụfụfụ polyurethane. A na-eji nke ikpeazụ eme ihe dị ka ihe na-agbanwe agbanwe n'ime arịa ụlọ, ihe ndina, na ihe mgbochi. N'ụdị siri ike a na-eji ya eme ihe maka mkpuchi, mkpuchi shei siri ike, ihe ụlọ, akụkụ akpaaka, wiil skate androller.

N'imepụta benzoic acid, benzaldehyde, ihe mgbawa, ihe eji esiji ákwà, na ọtụtụ ngwakọta organic ndị ọzọ; dị ka ihe mgbaze maka agba, lacquers, goms, resins; thinner maka ink, senti, e ji esiji ákwà; na mmịpụta ụkpụrụ dị iche iche sitere na osisi; dị ka mmanụ ụgbọala mgbakwunye.
