Mawu Oyamba
4-Amino-tetrahydropyran (yomwe imadziwikanso kuti 1-amino-4-hydro-epoxy-2,3,5,6-tetrahydropyran) ndi organic pawiri. Ndi madzi achikasu otumbululuka opanda mtundu okhala ndi mawonekedwe ofanana ndi gulu la amino la amine ndi mphete ya epoxy.
Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 4-amino-tetrahydropyran:
Ubwino:
- Maonekedwe: madzi opanda utoto mpaka owala achikasu;
- Kusungunuka: kusungunuka m'madzi, ma alcohols ndi zosungunulira za ether;
- Chemical properties: Ndi nucleophile yogwira ntchito yomwe imatha kutenga nawo mbali pamachitidwe ambiri achilengedwe, monga ma nucleophilic substitution reaction, kutsegulira kwa mphete, ndi zina.
Gwiritsani ntchito:
- 4-amino-tetrahydropyran angagwiritsidwe ntchito ngati reagent mu kaphatikizidwe organic ndipo angagwiritsidwe ntchito lithe zosiyanasiyana organic mankhwala, monga amides, carbonyl mankhwala, etc.;
- Pamakampani opanga utoto, itha kugwiritsidwa ntchito popanga utoto wa organic.
Njira:
Pali njira zingapo zokonzekera 4-amino-tetrahydropyran, ndipo zotsatirazi ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri:
Mpweya wa ammonia unawonjezeredwa ku tetrahydrofuran (THF), ndipo pa kutentha kochepa, 4-amino-tetrahydropyran inapezedwa ndi oxidizing benzotetrahydrofuran inoculation.
Zambiri Zachitetezo:
- 4-amino-tetrahydropyran ndi madzi oyaka moto omwe amayenera kusungidwa pamalo ozizira, opanda mpweya wabwino, kutali ndi moto;
- Pewani kutulutsa mpweya, kukhudzana ndi khungu ndikuyang'ana m'maso mukamagwiritsa ntchito, ndikutsuka nthawi yomweyo ndi madzi ngati mwakumana mwangozi;
- Pewani kutulutsa mpweya woyaka, nthunzi kapena fumbi panthawi yogwira ntchito;
- Valani zida zodzitetezera zoyenera monga magolovesi, magalasi ndi zovala zodzitetezera mukamagwiritsa ntchito;
