Isishwankathelo

I-N-methylaniline yeyona mveliso iphambili kuthotho lwe-N-alkyl aromatic amine kwaye iphakathi ebalulekileyo kwiikhemikhali ezintle. Isebenziseka lula kakhulu. Iseti yokuqala yezixhobo zemveliso zelizwe lam yakhiwa ngoncedo oluvela kwiSoviet Union yangaphambili ngeminyaka yoo-1950. Ezi mveliso zazisetyenziselwa kakhulu ukwenza ii-centralizers eziqhumayo kwaye zazisoloko zisetyenziselwa ukuxuba ipetroli eqhutywa ngokuthe ngqo. Ekubeni ipetroli eqhutywa ngokuthe ngqo ine-n-alkanes ezininzi kunye nenani eliphantsi le-octane, isetyenziswa ngokubanzi Ke ngoko, abanye oochwephesha basebenzisa ipetroli eqhutywa ngokuthe ngqo njengeoyile esisiseko yepetroli edibeneyo, kwaye bonyusa inani le-octane ngokongeza i-N-methylaniline ukufezekisa iinjongo zotyalo-mali oluphantsi kunye nokusebenza kakuhle okuphezulu.

Iimpawu zomzimba nezekhemikhali

I-N-methylaniline lulwelo olunamafutha olungenambala kubushushu begumbi. Inyibilika kwi-ethanol, i-ether, kunye ne-chloroform, ayinyibiliki emanzini, ayilahleki lula ngumphunga, kodwa ayilungelanga ukusasazwa kwiisilinda zeenjini ezineesilinda ezininzi. Izinzile ngokwendalo kwaye ayiboli lula emoyeni nakwiindawo ezimnyama. Iimpawu eziphambili zepetroli exutyiweyo ene-N-methylaniline antiknock agent livumba, uxinano oluphezulu, i-gum engahlanjwanga engagungqiyo, ixabiso eliphantsi le-olefin, kunye nesidingo see-arhente ze-antiknock ezincedisayo ezifana ne-MTBE kunye ne-MMT.

Isicelo

I-N-methylaniline yimveliso yekhemikhali entle enokusetyenziswa okubanzi. Isetyenziswa kakhulu ekwenzeni izibulali zinambuzane, iidayi, izinto ezidibanisa idayi, izongezo zerabha kunye nezinto eziqinisayo eziqhumayo. Ingasetyenziswa njenge-solvent kunye ne-acid acceptor kwi-organic synthesis. Izinto ezidibanisa i-Chemicalbook, izinto ezifunxa i-acid kunye nezinto ezinyibilikisayo. Kwishishini ledayi, isetyenziswa kwimveliso ye-cationic brilliant red FG, i-cationic pink B, i-reactive yellow-brown KGR, njl. Ingasetyenziswa kwakhona ukwandisa inani le-octane yepetroli kunye ne-organic synthesis, kwaye ingasetyenziswa njenge-solvent.

Ulwelo olunamafutha olungenambala ukuya kubomvu olumdaka olunokutsha. Lunyibilika kwi-ethanol, i-ether, i-chloroform, lunyibilika kancinci emanzini. Beka i-gradient mthubi.

Iipropati zeekhemikhali Ayinambala ukuya kubomvu mdaka, ulwelo oluvuthayo olunamafutha. Iyanyibilika kancinci emanzini, iyanyibilika kwi-ethanol, i-ether kunye ne-chloroform. Isetyenziswa njenge-dye intermediate.
