3,5-difluorobenzaldehyde jẹ agbo-ara Organic pẹlu agbekalẹ kemikali C7H4F2O. Atẹle jẹ apejuwe ti awọn ohun-ini, awọn lilo, igbaradi ati alaye ailewu ti agbo:
Awọn ohun-ini: 3,5-difluorobenzaldehyde jẹ aini awọ si ina ofeefee to lagbara pẹlu õrùn phenone pataki kan. O ni iwuwo ti 1.383g/cm³, aaye yo ti 48-52°C, ati aaye didan ti 176-177°C. 3,5-difluorobenzaldehyde jẹ insoluble ninu omi, ṣugbọn tiotuka ninu awọn ohun elo ti o wa ni erupẹ bi ethanol, ether, ati benzene.
Nlo: 3,5-difluorobenzaldehyde ni a maa n lo gẹgẹbi agbedemeji ni iṣelọpọ Organic. O le ṣee lo lati ṣapọpọ ọpọlọpọ awọn agbo ogun Organic ti o ni fluorine, pataki fun awọn aati kemikali ti o ṣafihan awọn ọta fluorine sinu awọn ohun alumọni Organic. Ni afikun, o tun le ṣee lo bi agbedemeji sintetiki fun awọn oogun, awọn ipakokoropaeku ati awọn awọ.
ọna igbaradi: ọna igbaradi ti 3,5-difluorobenzaldehyde ni a le gba nipasẹ didaṣe 3,5-difluorobenzyl methanol pẹlu acid aldehyde reagent (gẹgẹbi trichloroformic acid, bbl). Awọn ọna sintetiki kan pato le tọka si Iwe-afọwọkọ Synthesis Organic ati awọn iwe ti o jọmọ.
Alaye aabo: 3,5-difluorobenzaldehyde jẹ kemikali ati pe o nilo lati lo lailewu. O jẹ irritating ati ibajẹ ati pe o le fa ibajẹ si oju, awọ ara ati eto atẹgun. Awọn ohun elo aabo ti ara ẹni ti o yẹ gẹgẹbi awọn goggles, awọn ibọwọ ati awọn apata oju yẹ ki o wọ lakoko lilo. Tẹle awọn iṣe ailewu yàrá ati fipamọ, mu ati sọ ohun elo naa daadaa.
