Ubungozi Nokuphepha
| Izimpawu Eziyingozi | I-Xn - Iyingozi |
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | 26 - Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. |
| I-WGK Germany | 3 |
99528-42-4 - Imvelo
| ukuzungeza okuthile | -48 ° (C=1 KU-CHLOROFORM) |
| umsebenzi we-optical (umsebenzi wokukhanya) | [α]20/D -48.0°, c = 1 ku-chloroform |
99528-42-4 - Ulwazi Lwereferensi
| sebenzisa | (S)-1-(4-chlorophenyl) i-ethanol iyisisekelo sezinto ezingavuthiwe zokuhlanganiswa kohlobo olusha lwe-N,N'-dimethylpiperazine enekhono lokubopha insimbi. |
Isingeniso esifushane
(S)-1-(4-chlorophenyl)ithanol isakhi esiphilayo. Kuyi-molecule ye-chiral enesakhiwo esinjengendandatho esinwetshiwe. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Ikhwalithi:
- Ukubukeka: (S)-1-(4-chlorophenyl)thanol uketshezi olungenambala ukuya kokuphuzi ngokukhanyayo.
- Iyancibilika: Ingancibilika kuzincibilikisi eziningi eziphilayo, njengotshwala, ama-ether nama-hydrocarbon anephunga elimnandi.
Sebenzisa:
- (S)-1-(4-chlorophenyl) ithanol ivamise ukusetshenziswa njengendawo emaphakathi ekuhlanganiseni kwezinto eziphilayo.
- Ingasetshenziswa futhi ekulungiseleleni ama-chiral compounds, ama-chiral ligands, kanye nama-chiral catalysts, phakathi kokunye.
Indlela:
- (S)-1-(4-chlorophenyl)thanol ingahlanganiswa ngezinyathelo ezilandelayo:
1. I-ethylene acetonitrile incishiswa nge-4-chlorobenzaldehyde ukuze yakhe i-N-[(4-chlorobenzene)methyl]ethyleneacetonitrile.
2. Lokhu okuphakathi kube sekushisisa nge-sodium hydroxide ne-ethanol ukuze kukhiqizwe (S)-1-(4-chlorophenyl)thanol.
Ulwazi Lokuphepha:
- (S)-1-(4-chlorophenyl)thanol ngokuvamile iphephe kakhulu ngaphansi kwezimo ezivamile zokusebenza, kodwa kusenezinqubo ezithile eziyisisekelo zokusebenza zokuphepha zaselabhorethri okudingeka zilandelwe.
- Kungaba into ecasulayo emehlweni, esikhumbeni, nasemgudwini wokuphefumula futhi kufanele kugwenywe ukuthintana ngqo nokuhogela. Izinto zokuzivikela ezifanele ezifana namagilavu, izibuko zokuzivikela, namamaski kufanele zigqokwe lapho uphathwa.
- Lapho uphatha noma ugcina inhlanganisela, kufanele kuthathwe ukunakekelwa ukuze kugwenywe ukuvutha kanye nokushisa okuphezulu.
- Uma usebenzisa futhi ulahla, bheka amaSpredishithi eDatha Yezokuphepha afanelekile namalebula amakhemikhali, futhi ulandele imihlahlandlela yokusebenza ukuze uqinisekise ukuphepha kanye nezingozi zempilo ziyancishiswa.
