Intshayelelo
I-4-Amino-tetrahydropyran (eyaziwa nangokuthi i-1-amino-4-hydro-epoxy-2,3,5,6-tetrahydropyran) i-organic compound. Lulwelo olungenambala ukuya kumthubi oluluthuthu olunesakhiwo esifana neqela le-amine elisebenzayo kunye neringi ye-epoxy.
Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-4-amino-tetrahydropyran:
Umgangatho:
- Imbonakalo: ayinambala ukuya kulwelo olumthubi olukhanyayo;
- Ukunyibilika: ukunyibilika emanzini, utywala kunye nezinyibilikisi ze-ether;
- Iipropati zeMichiza: I-nucleophile esebenzayo enokuthi ithathe inxaxheba kwiimpendulo ezininzi zezinto eziphilayo, ezifana ne-nucleophilic substitution reactions, ukuphendulwa kweringi, njl.
Sebenzisa:
- I-4-amino-tetrahydropyran ingasetyenziselwa njenge-reagent kwi-organic synthesis kwaye ingasetyenziselwa ukudibanisa iintlobo ezahlukeneyo zezinto eziphilayo, ezifana ne-amides, i-carbonyl compounds, njl.;
- Kwishishini ledayi, linokusetyenziswa kwi-synthesis ye-organic dyes.
Indlela:
Kukho iindlela ezininzi zokulungiselela i-4-amino-tetrahydropyran, kwaye ilandelayo yenye yeendlela eziqhelekileyo ezisetyenziswayo:
Igesi ye-ammonia yongezwa kwi-tetrahydrofuran (THF), kwaye kwiqondo lokushisa eliphantsi, i-4-amino-tetrahydropyran yafunyanwa nge-oxidizing benzotetrahydrofuran inoculation.
Ulwazi ngoKhuseleko:
- I-4-amino-tetrahydropyran iyilwelo olunokutsha olufanele lugcinwe kwindawo epholileyo, enomoya, kude nomlilo;
- Gwema ukuphefumla, ukudibana kwesikhumba kunye nokudibana kwamehlo ngexesha lokusetyenziswa, kwaye uhlambe ngokukhawuleza ngamanzi xa udibana nengozi;
- Gwema ukuveliswa kweegesi ezinokutsha, umphunga okanye uthuli ngexesha lokusebenza;
- Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglasi kunye nempahla yokukhusela xa usetyenziswa;
