Intshayelelo
I-Dimethoxyaniline (i-N-methylaniline) yi-organic compound. Yi-amine ephilayo ene-alcohol-amine nature kunye ne-pKa malunga ne-4.64. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-dimethoxyaniline:
Umgangatho:
- Imbonakalo: I-Dimethoxyaniline lulwelo olungenambala ukuya kumthubi okhanyayo.
- Ukunyibilika: Inokunyibilika kwizinyibilikisi ezininzi zezinto eziphilayo, ezinjengeealkoholi, ii-ethers, kunye neehydrocarbon ezikloriniwe.
- Ubutyhefu: Yityhefu, kwaye ukuba sesichengeni okanye ukuphefumla umphunga okanye ulwelo oluphezulu kunokuba yingozi empilweni.
Sebenzisa:
- I-Dimethoxyaniline isetyenziswa ikakhulu njengento ephakathi kwi-organic synthesis.
- Isenokusetyenziswa njenge-catalyst ukuba yongezwe kwisistim yokusabela ukuququzelela ukuphendulwa kweekhemikhali ezithile.
- I-reactivity ye-dimethoxyaniline kunye nezinye iikhompawundi, ukusabela kwayo kunye ne-carbamate kunye ne-amide compounds iba yinyathelo elibalulekileyo kwi-synthesis ye-compounds entsha.
Indlela:
- I-Dimethoxyaniline inokulungiswa ngokusabela kwe-aniline kunye ne-methanol. Iimpendulo phantsi kweemeko ze-acidic, ezifana nokusetyenziswa kwe-hydrochloric acid okanye i-sulfuric acid njenge-catalysts, inokwenza kube lula ukuphendula.
Ulwazi ngoKhuseleko:
- I-Lemonaniline iyacaphukisa ulusu kunye namehlo kwaye inokuba yingozi kwiinkqubo zokuphefumla kunye nezokwetyisa.
- Izilumkiso ezifanelekileyo ezinjengokunxiba iiglavu zokukhusela, izibuko, kunye nempahla yokukhusela iyafuneka xa usebenzisa i-dimethoxyaniline ukuqinisekisa iimeko zovavanyo ezinomoya kakuhle.
- Xa ugcina kwaye uphatha i-bimethoxyaniline, kunqande ukudibana ne-oxidants eyomeleleyo kunye nezinto ezinokutsha, kwaye ugcine kwindawo epholileyo, enomoya kunye neyomileyo.
