Ọrọ Iṣaaju
1,3-Difluorobenzene jẹ ẹya Organic yellow. Atẹle jẹ ifihan alaye si awọn ohun-ini, awọn lilo, awọn ọna igbaradi ati alaye ailewu ti 1,3-difluorobenzene:
Didara:
1,3-Difluorobenzene jẹ agbo-ara organofluorine pẹlu iduroṣinṣin kemikali giga. Kii ṣe ina ṣugbọn ṣe atunṣe pẹlu awọn aṣoju oxidizing to lagbara. 1,3-Difluorobenzene jẹ tiotuka ni awọn ohun elo ti o wọpọ gẹgẹbi ethanol, ether ati chloroform, ati insoluble ninu omi.
Lo:
1,3-difluorobenzene ni iye ohun elo kan ninu iṣelọpọ Organic. O le ṣee lo bi reagent ifaseyin ni iṣelọpọ Organic, fun apẹẹrẹ bi reagent fluorinating fun awọn agbo ogun oorun. 1,3-difluorobenzene tun le ṣee lo ni iṣelọpọ ti awọn ohun elo fluorescent, igbaradi ti awọn ohun elo optoelectronic Organic ati awọn aaye miiran.
Ọna:
1,3-Difluorobenzene le wa ni ipese nipasẹ fluorination ti benzene. Awọn ọna igbaradi ti o wọpọ jẹ hydrogen fluoride bi oluranlowo fluoride tabi lilo awọn eka fluoride ferrous fun awọn aati fluorination.
Alaye Abo:
Awọn iṣọra ailewu atẹle yẹ ki o mu nigba lilo 1,3-difluorobenzene:
1.1,3-Difluorobenzene ni awọn majele kan, eyiti o le fa ipalara ni ifọwọkan pẹlu awọ ara, ifasimu ti gaasi tabi ingestion lairotẹlẹ. Ohun elo aabo ti ara ẹni ti o yẹ gẹgẹbi awọn ibọwọ, awọn oju aabo, ati awọn iboju iparada yẹ ki o wọ lakoko lilo.
2. Yago fun olubasọrọ pẹlu awọn aṣoju oxidizing lagbara lati yago fun ina tabi bugbamu.
3. O yẹ ki o wa ni ipamọ ni ibi gbigbẹ, itura ati daradara, kuro lati ina ati awọn ohun elo ti o ni ina.
5. Yẹra fun idapọ pẹlu awọn kemikali miiran ki o yago fun awọn ọmọde ati awọn eniyan ti ko mọ bi a ṣe le ṣiṣẹ.
