Ọrọ Iṣaaju
2-Bromo-5- (trifluoromethyl) pyridine (ti a tun mọ ni BTFP) jẹ ẹya-ara Organic. Atẹle jẹ ifihan si iseda rẹ, lilo, ọna igbaradi ati alaye aabo:
Didara:
- Irisi: White ri to
- iwuwo molikula: 206.00 g / mol
- Solubility: BTFP jẹ irọrun tiotuka ninu awọn nkan ti ara ẹni (fun apẹẹrẹ, awọn ọti-lile, ethers, ketones) ṣugbọn o kere si tiotuka ninu omi.
Lo:
- Gẹgẹbi agbedemeji iṣelọpọ: BTFP ni lilo pupọ ni igbaradi ti awọn agbedemeji iṣelọpọ Organic, gẹgẹbi awọn agbo ogun pyridine, awọn agbo ogun aromatic, ati bẹbẹ lọ.
- Gẹgẹbi ligand: BTFP le ṣee lo bi ligand fun awọn eka irin ati pe o ni ipa ninu ọpọlọpọ awọn aati katalytic ati igbaradi awọn ohun elo iṣẹ.
- Gẹgẹbi reagent: BTFP ṣe ipa pataki ninu iṣelọpọ Organic, gẹgẹ bi ifarapọ idapọ, ifarọpo, ati iṣe idinku.
Ọna:
2-Bromo-5- (trifluoromethyl) pyridine le ṣepọ nipasẹ awọn igbesẹ wọnyi:
1. Tu 2-amino-5- (trifluoromethyl) pyridine ninu epo-ara ti o dara, gẹgẹbi oti tabi ketone.
2. Fi awọn agbo ogun bromine kun (fun apẹẹrẹ hydrogen bromide, methyl bromide).
3. Ṣe iṣeduro ni iwọn otutu ti o tọ ati awọn ipo igbiyanju.
4. Ṣe àlẹmọ ọja naa ki o si ṣe crystallization ati ìwẹnumọ.
Alaye Abo:
- BTFP le ṣinṣin tabi crystallize ni awọn iwọn otutu kekere, jọwọ tọju ni iwọn otutu yara ki o yago fun crystallization.
- Wọ awọn ibọwọ aabo ti o yẹ ati awọn gilaasi lakoko iṣẹ lati yago fun olubasọrọ pẹlu awọ ara ati oju.
- Yẹra fun simi eruku rẹ tabi vapors, bi BTFP le ni ipa irritating lori atẹgun atẹgun.
- Tọkasi itọnisọna ailewu ti o yẹ nigba lilo tabi mimu BTFP, ki o si sọ egbin ati awọn nkanmimu nu ni deede.
