Ukubuka konke

I-N-methylaniline ingumkhiqizo oyinhloko ochungechungeni lwe-N-alkyl aromatic amine futhi iyingxenye ebalulekile yamakhemikhali amahle. Isebenziseka kakhulu. Isethi yokuqala yemishini yokukhiqiza yezwe lami yakhiwa ngosizo oluvela eSoviet Union yangaphambili ngawo-1950. Imikhiqizo yayisetshenziswa kakhulu ukwenza ama-centralizer aqhumayo futhi yayivame ukusetshenziselwa ukuhlanganisa uphethiloli ogijima ngqo. Njengoba uphethiloli ogijima ngqo une-n-alkanes eningi kanye nenombolo ye-octane ephansi, ngokuvamile isetshenziswa ku-Ngakho-ke, abanye ochwepheshe basebenzisa uphethiloli ogijima ngqo njengamafutha ayisisekelo kaphethiloli ohlanganisiwe, futhi bandise inombolo ye-octane ngokungeza i-N-methylaniline ukuze kufezwe imigomo yokutshalwa kwezimali okuphansi kanye nokusebenza kahle okuphezulu.

Izakhiwo zomzimba nezamakhemikhali

I-N-methylaniline iwuketshezi olunamafutha olungenambala ekamelweni lokushisa. Incibilika ku-ethanol, i-ether, kanye ne-chloroform, ayincibiliki emanzini, ayilahleki kalula ngokuhwamuka, kodwa ayivumeli ukusatshalaliswa kumasilinda ezinjini ezinamasilinda amaningi. Izinzile ngokwemvelo futhi ayiboli kalula emoyeni nasezindaweni ezimnyama. Izici eziyinhloko zikaphethiloli oxutshwe ne-N-methylaniline antiknock agent yiphunga, ukuminyana okuphezulu, i-gum engahlanzwanga kahle, inani eliphansi le-olefin, kanye nesidingo sama-ejenti okusiza okulwa nokuknock njenge-MTBE kanye ne-MMT.

Isicelo

I-N-methylaniline iwumkhiqizo omuhle wamakhemikhali onokusetshenziswa okubanzi. Isetshenziswa kakhulu ekwenzeni izibulala-zinambuzane, amadayi, izinto ezihlanganisa udayi, izithasiselo zerabha kanye neziqinisi eziqhumayo. Ingasetshenziswa futhi njenge-solvent kanye ne-acid acceptor yokwenziwa kwezinto eziphilayo. Izinto ezihlanganisa izinto eziphilayo, izinto ezihlanganisa izinto eziphilayo kanye nezinto ezihlanganisa izinto eziphilayo. Embonini yodayi, isetshenziswa ekukhiqizweni kwe-cationic brilliant red FG, i-cationic pink B, i-reactive yellow-brown KGR, njll. Ingasetshenziswa futhi ukwandisa inani le-octane likaphethiloli kanye nokwakheka kwezinto eziphilayo, futhi ingasetshenziswa njenge-solvent.

Uketshezi olunamafutha oluvuthayo olungenambala kuya kobomvu olunsundu. Luncibilika ku-ethanol, i-ether, i-chloroform, luncibilika kancane emanzini. Beka umbala ophuzi oluhlaza.

Izakhiwo Zamakhemikhali Ayinambala kuya kobomvu, uketshezi oluvuthayo olunamafutha. Luncibilika kancane emanzini, luncibilika ku-ethanol, i-ether kanye ne-chloroform. Lusetshenziswa njenge-dye intermediate.
