N-methylaniline yog cov khoom tseem ceeb hauv N-alkyl aromatic amine series thiab yog ib qho tseem ceeb hauv cov tshuaj zoo. Muaj ntau yam siv tau. Kuv lub teb chaws thawj cov khoom siv tsim khoom tau tsim los ntawm kev pab los ntawm lub tebchaws Soviet yav dhau los hauv xyoo 1950. Cov khoom no feem ntau yog siv los ua cov khoom siv tawg thiab feem ntau siv los sib tov roj av ncaj. Txij li thaum roj av ncaj muaj ntau n-alkanes thiab tus lej octane qis dua, nws feem ntau yog siv rau hauv Yog li ntawd, qee tus kws tshaj lij siv roj av ncaj ua roj rau roj av sib xyaw, thiab nce tus lej octane los ntawm kev ntxiv N-methylaniline kom ua tiav lub hom phiaj ntawm kev nqis peev tsawg thiab kev ua haujlwm siab.

Cov khoom siv lub cev thiab tshuaj lom neeg

N-methylaniline yog ib yam roj uas tsis muaj xim nyob rau hauv chav tsev kub. Yaj hauv ethanol, ether, thiab chloroform, tsis yaj hauv dej, tsis yooj yim poob los ntawm kev ua pa, tab sis tsis zoo rau kev faib tawm hauv cov tog raj kheej ntawm cov cav ntau lub tog raj kheej. Nws ruaj khov hauv qhov xwm txheej thiab tsis yooj yim lwj hauv huab cua thiab qhov chaw tsaus ntuj. Cov yam ntxwv tseem ceeb ntawm roj av sib xyaw nrog N-methylaniline antiknock agent yog ntxhiab tsw, siab ceev, tsis ruaj khov tsis ntxuav gum, qis olefin tus nqi, thiab qhov xav tau cov neeg sawv cev antiknock xws li MTBE thiab MMT.

Daim Ntawv Thov

N-methylaniline yog ib yam khoom siv tshuaj zoo uas muaj ntau yam kev siv. Nws feem ntau yog siv los ua tshuaj tua kab, xim pleev, xim nruab nrab, roj hmab ntxiv thiab cov khoom ruaj khov tawg. Nws kuj tseem siv tau ua cov kuab tshuaj thiab cov kua qaub rau kev tsim cov organic. Cov tshuaj nruab nrab, cov kua qaub nqus thiab cov kuab tshuaj. Hauv kev lag luam xim pleev, nws yog siv rau hauv kev tsim cov xim liab ci ntsa iab FG, cationic liab dawb B, reactive daj-xim av KGR, thiab lwm yam. Nws kuj tseem siv tau los ua kom cov roj av thiab cov organic synthesis muaj octane ntau dua, thiab kuj siv tau ua cov kuab tshuaj.

Cov Khoom Siv Tshuaj

Tsis muaj xim rau xim av liab, roj, thiab yooj yim hlawv. Yaj me ntsis hauv dej, yaj hauv ethanol, ether thiab chloroform. Siv ua xim nruab nrab.
