Isingeniso
I-Dimethoxyaniline (N-methylaniline) iyinhlanganisela yemvelo. I-amine yemvelo enemvelo ye-alcohol-amine kanye ne-pKa engaba ngu-4.64. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dimethoxyaniline:
Ikhwalithi:
- Ukubukeka: I-Dimethoxyaniline iwuketshezi olungenambala ukuya kokuphuzi ngokukhanyayo.
- Ukunyibilika: Kungancibilika kuzincibilikisi eziningi eziphilayo, njengotshwala, ama-ether, nama-hydrocarbon ane-chlorine.
- Ubuthi: Yinto enobuthi, futhi ukuchayeka noma ukuhogela ukugcwala okuphezulu komhwamuko noma uketshezi kungaba yingozi empilweni.
Sebenzisa:
- I-Dimethoxyaniline isetshenziswa kakhulu njengendawo ephakathi ku-organic synthesis.
- Ingasetshenziswa futhi njenge-catalyst yokwengezwa ohlelweni lokusabela ukuze kube lula ukusabela okuthile kwamakhemikhali.
- Ukuphinda kusebenze kwe-dimethoxyaniline nezinye izinhlanganisela, ukusabela kwayo nge-carbamate kanye nezinhlanganisela ze-amide kuba isinyathelo esibalulekile ekuhlanganisweni kwezinhlanganisela ezintsha.
Indlela:
- I-Dimethoxyaniline ingalungiswa ngokusabela kwe-aniline ne-methanol. Ukusabela ngaphansi kwezimo ezine-acidic, ezifana nokusetshenziswa kwe-hydrochloric acid noma i-sulfuric acid njengama-catalysts, kungenza kube lula ukusabela.
Ulwazi Lokuphepha:
- I-Lemonaniline iyacasula esikhumbeni nasemasweni futhi ingaba yingozi ezinhlelweni zokuphefumula nezokugaya ukudla.
- Izinyathelo ezifanele ezinjengokugqoka amagilavu okuzivikela, izibuko, nezingubo zokuzivikela ziyadingeka lapho usebenzisa i-dimethoxyaniline ukuze kuqinisekiswe izimo zokuhlola ezinomoya omuhle.
- Lapho ugcina futhi uphatha i-bimethoxyaniline, gwema ukuthintana nama-oxidants aqinile nezinto ezivuthayo, futhi ugcine endaweni epholile, engenamoya neyomile.
