Dulmar Guud

N-methylaniline waa badeecada ugu weyn ee taxanaha amine aromatic N-alkyl waana mid muhiim u ah kiimikooyinka fiican. Aad bay u kala duwan yihiin. Qalabka wax soo saarka ee ugu horreeyay ee dalkayga waxaa la dhisay iyadoo la kaashanayo Midowgii Soofiyeeti ee hore sanadihii 1950-meeyadii. Badeecadaha waxaa inta badan loo isticmaali jiray in lagu sameeyo qalab qarxa waxaana badanaa loo isticmaali jiray in lagu qaso shidaalka tooska ah. Maadaama shidaalka tooska ah uu leeyahay n-alkanes badan iyo tiro octane oo hooseeya, guud ahaan waxaa loo isticmaalaa Sidaa darteed, farsamoyaqaannada qaar ayaa isticmaala shidaalka tooska ah sida saliidda salka u ah shidaalka isku dhafan, waxayna kordhiyaan tirada octane iyagoo ku daraya N-methylaniline si loo gaaro yoolalka maalgashiga hooseeya iyo hufnaanta sare.

Sifooyinka jirka iyo kiimikada

N-methylaniline waa dareere saliid ah oo aan midab lahayn heerkulka qolka. Waxaa lagu milmaa ethanol, ether, iyo kloroform, oo aan ku milmi karin biyaha, si fudud looma lumin karo uumiga, laakiin kuma habboona qaybinta dhululubada matoorada dhululubada badan. Waa mid deggan dabeecadda mana si fudud u burburo hawada iyo jawiga mugdiga ah. Astaamaha ugu muhiimsan ee shidaalka isku dhafan ee leh wakiilka N-methylaniline antiknock waa ur, cufnaan sare, xanjo aan degganayn, qiimo olefin oo hooseeya, iyo baahida loo qabo wakiilada antiknock ee caawiya sida MTBE iyo MMT.

Codsiga

N-methylaniline waa badeeco kiimiko oo fiican oo leh isticmaal badan. Waxaa inta badan loo isticmaalaa in lagu sameeyo sunta cayayaanka, rinjiyeyaasha, dhexdhexaadinta rinjiga, waxyaabaha lagu daro caagga iyo xasiliyeyaasha qarxa. Waxa kale oo loo isticmaali karaa sidii dareere iyo aashito aqbale ah oo loogu talagalay isku-darka dabiiciga ah. Qalabka kiimikada, nuugayaasha aashitada iyo dareeraha. Warshadaha rinjiga, waxaa loo isticmaalaa soo saarista FG cas oo dhalaalaya oo cationic ah, casaan cationic ah B, KGR huruud-bunni ah oo falcelin leh, iwm. Waxa kale oo loo isticmaali karaa in lagu kordhiyo tirada octane ee shidaalka iyo isku-darka dabiiciga ah, waxaana sidoo kale loo isticmaali karaa sidii dareere.

Dareere saliid leh oo guban kara oo aan midab lahayn ilaa bunni casaan ah. Ku milma ethanol, ether, chloroform, oo si yar ugu milma biyaha. Dhig jaalle jaalle ah.

Sifooyinka Kiimikada: Dareere saliid leh oo guban kara oo aan midab lahayn ilaa bunni casaan ah. Si yar ugu milma biyaha, ku milma ethanol, ether iyo kloroform. Waxaa loo isticmaalaa midab dhexdhexaad ah.
