N-methylaniline yog cov khoom tseem ceeb hauv N-alkyl aromatic amine series thiab ib qho tseem ceeb nruab nrab ntawm cov tshuaj zoo. Ntau yam heev. kuv lub teb chaws thawj txheej ntawm cov khoom tsim tau tsim nrog kev pab los ntawm lub qub Soviet Union nyob rau hauv 1950s. Cov khoom no tsuas yog siv los ua cov khoom siv hluav taws xob tawg thiab feem ntau siv los sib tov ncaj nraim-khiav Chemicalbook roj av. Txij li cov roj av ncaj nraim muaj ntau n-alkanes thiab qis dua tus lej octane, feem ntau yog siv rau hauv Yog li ntawd, qee cov kws tshaj lij siv cov roj av ncaj qha raws li cov roj hauv paus rau cov roj av sib xyaw, thiab nce tus lej octane los ntawm kev ntxiv N-methylaniline kom ua tiav. cov hom phiaj ntawm kev nqis peev tsawg thiab kev ua haujlwm siab.

Lub cev thiab tshuaj muaj zog:

N-methylaniline yog cov kua tsis muaj xim oily ntawm chav tsev kub. Soluble nyob rau hauv ethanol, ether, thiab chloroform, insoluble nyob rau hauv dej, tsis yooj yim poob los ntawm evaporation, tab sis tsis conducive rau faib nyob rau hauv lub tog raj kheej ntawm ntau lub tog raj kheej engine. Nws yog ruaj khov nyob rau hauv cov xwm thiab tsis decompose yooj yim nyob rau hauv huab cua thiab tsaus ib puag ncig. Cov yam ntxwv tseem ceeb ntawm cov roj av sib xyaw nrog N-methylaniline antiknock tus neeg sawv cev yog cov ntxhiab tsw, siab ceev, tsis ruaj tsis khov cov pos hniav, tsis muaj nqi olefin, thiab xav tau cov tshuaj tiv thaiv kab mob xws li MTBE thiab MMT.

Daim ntawv thov

N-methylaniline yog cov khoom siv tshuaj zoo nrog ntau yam kev siv. Nws yog tsuas yog siv los ua tshuaj tua kab, dyes, dye intermediates, roj hmab additives thiab explosive stabilizers. Nws kuj tseem siv tau los ua cov kuab tshuaj thiab cov kua qaub rau cov organic synthesis. Chemicalbook intermediates, acid absorbers thiab cov kuab tshuaj. Nyob rau hauv kev lag luam dyeing, nws yog siv nyob rau hauv zus tau tej cov cationic ci ntsa iab liab FG, cationic liab B, reactive daj-xim av KGR, thiab lwm yam. Nws kuj yuav siv tau los ua kom cov octane tus naj npawb ntawm cov roj av thiab organic synthesis, thiab kuj siv tau. raws li qhov hnyav.
