N-methylaniline ndiye chinthu chachikulu chomwe chimagwiritsidwa ntchito mu N-alkyl aromatic amine series komanso chinthu chofunikira kwambiri pakupanga mankhwala abwino. Chogwiritsidwa ntchito mosiyanasiyana kwambiri. Zida zoyamba zopangira dziko langa zidapangidwa mothandizidwa ndi Soviet Union yakale m'zaka za m'ma 1950. Zogulitsazi zinkagwiritsidwa ntchito makamaka popanga ma centralizer ophulika ndipo nthawi zambiri zinkagwiritsidwa ntchito kusakaniza mafuta oyenda molunjika. Popeza mafuta oyenda molunjika ali ndi n-alkanes ambiri komanso octane yotsika, nthawi zambiri amagwiritsidwa ntchito mu Chifukwa chake, akatswiri ena amagwiritsa ntchito mafuta oyenda molunjika ngati mafuta oyambira a mafuta osakanikirana, ndikuwonjezera octane number powonjezera N-methylaniline kuti akwaniritse zolinga zawo zotsika ndalama komanso magwiridwe antchito apamwamba.

Kapangidwe ka thupi ndi mankhwala

N-methylaniline ndi madzi amafuta opanda mtundu pa kutentha kwa chipinda. Amasungunuka mu ethanol, ether, ndi chloroform, osasungunuka m'madzi, samatayika mosavuta chifukwa cha nthunzi, koma samalola kufalikira m'masilinda a injini zamasilinda ambiri. Ndi okhazikika mwachilengedwe ndipo samawola mosavuta mumlengalenga ndi m'malo amdima. Makhalidwe akuluakulu a mafuta osakanikirana ndi mankhwala oletsa kugwedezeka a N-methylaniline ndi fungo, kuchuluka kwambiri, chingamu chosakhazikika, mtengo wotsika wa olefin, komanso kufunikira kwa mankhwala othandizira oletsa kugwedezeka monga MTBE ndi MMT.

Kugwiritsa ntchito

N-methylaniline ndi mankhwala abwino kwambiri omwe amagwiritsidwa ntchito m'njira zosiyanasiyana. Amagwiritsidwa ntchito kwambiri popanga mankhwala ophera tizilombo, utoto, zinthu zopaka utoto, zowonjezera za rabara ndi zokhazikika. Ingagwiritsidwenso ntchito ngati chosungunulira ndi cholandirira asidi popanga zinthu zachilengedwe. Zinthu zopaka utoto, zopopera asidi ndi zinthu zosungunulira. Mu makampani opanga utoto, imagwiritsidwa ntchito popanga cationic brilliant red FG, cationic pink B, reactive yellow-brown KGR, ndi zina zotero. Ingagwiritsidwenso ntchito kuwonjezera kuchuluka kwa octane kwa mafuta ndi zinthu zachilengedwe, komanso ingagwiritsidwenso ntchito ngati chosungunulira.

Katundu wa Mankhwala

Madzi oyaka opanda utoto mpaka ofiira a bulauni. Amasungunuka pang'ono m'madzi, amasungunuka mu ethanol, ether ndi chloroform. Amagwiritsidwa ntchito ngati utoto wapakati.
