Isingeniso
I-4-Amino-tetrahydropyran (eyaziwa nangokuthi i-1-amino-4-hydro-epoxy-2,3,5,6-tetrahydropyran) iyinhlanganisela yezinto eziphilayo. Iwuketshezi olungenambala kuya kokuphuzi okuphaphathekile olunesakhiwo esifana neqembu le-amino elisebenzayo nendandatho ye-epoxy.
Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-4-amino-tetrahydropyran:
Ikhwalithi:
- Ukubukeka: uketshezi olungenambala oluphuzi olukhanyayo;
- I-Solubility: i-soluble emanzini, utshwala kanye nezincibilikisi ze-ether;
- Izakhiwo zamakhemikhali: I-nucleophile esebenzayo engabamba iqhaza ekuphenduleni okuningi kwe-organic, njengokusabela kwe-nucleophilic esikhundleni, ukusabela kokuvula indandatho, njll.
Sebenzisa:
- I-4-amino-tetrahydropyran ingasetshenziswa njenge-reagent ku-organic synthesis futhi ingasetshenziswa ukuhlanganisa ama-organic compounds ahlukahlukene, njengama-amides, ama-carbonyl compounds, njll;
- Embonini yodayi, ingasetshenziswa ekuhlanganiseni udayi we-organic.
Indlela:
Kunezindlela eziningana zokulungiselela i-4-amino-tetrahydropyran, futhi okulandelayo kungenye yezindlela ezivame ukusetshenziswa:
Igesi ye-ammonia yengezwe ku-tetrahydrofuran (THF), futhi emazingeni okushisa aphansi, i-4-amino-tetrahydropyran itholwe nge-oxidizing inoculation ye-benzotetrahydrofuran.
Ulwazi Lokuphepha:
- I-4-amino-tetrahydropyran iwuketshezi oluvuthayo okufanele lugcinwe endaweni epholile, enomoya omuhle, kude nomlilo;
- Gwema ukuhogela, ukuthintana kwesikhumba kanye nokuthinta amehlo ngesikhathi usebenzisa, futhi ugeze ngokushesha ngamanzi uma kwenzeka ukuthintana ngephutha;
- Gwema ukukhiqizwa kwamagesi avuthayo, umusi noma uthuli ngesikhathi sokusebenza;
- Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko nezingubo zokuzivikela lapho usetshenziswa;
