2-Chloro-4-fluorobenzoic acid jẹ ẹya Organic yellow. Atẹle jẹ ifihan si awọn ohun-ini, awọn lilo, awọn ọna igbaradi ati alaye ailewu ti 2-chloro-4-fluorobenzoic acid:
Didara:
- Ifarahan: 2-Chloro-4-fluorobenzoic acid jẹ okuta kirisita funfun.
- Solubility: O ni solubility kekere ninu omi, ṣugbọn o ni solubility ti o dara ni awọn nkan ti o wa ni erupẹ (fun apẹẹrẹ, ethanol, acetone).
- Iduroṣinṣin: O jẹ agbopọ iduroṣinṣin, ṣugbọn olubasọrọ pẹlu awọn oxidants ti o lagbara ati awọn acids yẹ ki o yee.
Lo:
- Awọn agbedemeji kemikali: 2-chloro-4-fluorobenzoic acid le ṣee lo bi awọn agbedemeji kemikali ni iṣelọpọ Organic.
- Surfactant: O le ṣee lo bi awọn kan aise ohun elo fun surfactants ati ki o ni o dara dada aṣayan iṣẹ-ṣiṣe ati pipinka-ini.
- Awọn ohun elo ti o ni imọran: 2-chloro-4-fluorobenzoic acid le ṣee lo lati ṣeto awọn ohun elo ti o ni imọran, gẹgẹbi awọn adhesives-itọju-ina.
Ọna:
2-Chloro-4-fluorobenzoic acid le ṣee gba nipasẹ ifarọpo fluorochloro ti p-dichlorobenzoic acid tabi difluorobenzoic acid. Awọn ọna igbaradi kan le pẹlu aropo fluorochloro, fluorination tabi awọn aati aropo to dara miiran.
Alaye Abo:
- Majele ti: 2-chloro-4-fluorobenzoic acid jẹ ẹya organofluorine yellow, eyi ti o jẹ kere majele ti ju gbogbo organofluorine agbo. Sibẹsibẹ, o yẹ ki o ṣe itọju lati yago fun ifasimu tabi olubasọrọ.
- Irritation: O le fa irritation si awọn oju, awọ ara ati atẹgun atẹgun ati pe o yẹ ki o fọ ni kiakia lẹhin olubasọrọ.
- Awọn aṣoju ti npa ina: Ninu ina, piparẹ yẹ ki o ṣee ṣe pẹlu ohun elo imukuro ti o yẹ gẹgẹbi carbon dioxide, foomu tabi lulú gbigbẹ, yago fun lilo omi lati pa ina nitori pe o ni iyọkuro kekere ninu omi.
- Ibi ipamọ: 2-Chloro-4-fluorobenzoic acid yẹ ki o wa ni ipamọ ni ibi gbigbẹ, aaye ti o dara daradara, kuro lati ina ati awọn oxidants lagbara.
