Ifaara
O-difluorobenzene jẹ agbo-ara Organic. Atẹle jẹ ifihan si awọn ohun-ini, awọn lilo, awọn ọna igbaradi ati alaye ailewu ti o-difluorobenzene:
Didara:
- Ifarahan: O-difluorobenzene jẹ omi ti ko ni awọ tabi kirisita funfun.
- Solubility: O-difluorobenzene jẹ tiotuka ninu awọn nkan ti o nfo Organic gẹgẹbi awọn ọti, ethers ati benzene.
Lo:
O-difluorobenzene le ṣee lo bi ohun elo ibẹrẹ ati agbedemeji ni iṣelọpọ Organic, ati pe o lo pupọ ni oogun, ipakokoropaeku ati awọn aaye dai.
- O tun le ṣee lo bi aropo ninu awọn aṣọ, awọn olomi ati awọn lubricants.
O-difluorobenzene tun le ṣee lo ni ile-iṣẹ itanna, fun apẹẹrẹ gẹgẹbi paati awọn ohun elo kirisita olomi.
Ọna:
Awọn ọna akọkọ meji lo wa fun igbaradi o-difluorobenzene: iṣesi ti awọn agbo ogun fluorine pẹlu benzene ati ifasilẹ fluorination yiyan ti benzene fluorinated.
- Idahun ti awọn agbo ogun fluorine pẹlu benzene jẹ wọpọ, ati o-difluorobenzene le ṣee gba nipasẹ fluorination ti chlorobenzene nipasẹ gaasi fluorine.
- Yiyan fluorination ti fluorinated benzene nbeere lilo ti yiyan fluorinating reagents fun kolaginni.
Alaye Abo:
- Ifihan si o-difluorobenzene le fa ibinu si awọ ara, oju ati eto atẹgun, ati pe o yẹ ki o mu awọn iṣọra.
- Wọ awọn gilaasi aabo, awọn ibọwọ ati awọn aṣọ iṣẹ nigba lilo o-difluorobenzene, ati ṣetọju agbegbe ti o ni afẹfẹ daradara.
- Jeki kuro lati ina ati awọn iwọn otutu giga, ati tọju ni itura, aaye gbigbẹ.
- Ṣaaju lilo tabi mimu o-difluorobenzene mu, ka ati tẹle awọn itọnisọna mimu aabo ti o yẹ.
