Hydroquinone (HQ) (CAS: 123-31-9) imapangidwa ndi okosijeni wa aniline kapena phenol, ndi kuchepetsa quinone, kapena kuchokera ku acetylene ndi carbon monoxide.
Hydroquinone ndi chochepetsera chomwe chimagwiritsidwa ntchito popanga zithunzi, chomwe chimapangika pamaso pa oxidizing agents.M'makampani opanga zinthu zikhoza kuchitika monga bacteriostatic agent, mankhwala, ubweya wa ubweya, mafuta amoto, utoto, mankhwala achilengedwe, mapulasitiki, zokutira mwala, ndi styrene monomers.
Gwiritsani ntchito ngati chochepetsera zithunzi ndi mapulogalamu;monga reagent mu mtima wa ochepa mankwala;ngati antioxidant.Depigmentor.
Zithunzi zochepetsera ndi mapulogalamu;antioxidant;stabilizing wothandizira ma polima ena;wapakatikati popanga utoto ndi utoto wina;mu cosmetic formulations.
Hydroquinone imagwiritsidwa ntchito popanga zithunzi (zakuda ndi zoyera, X-ray, ndi ma microfilms), m'mapulasitiki, mu utoto watsitsi monga antioxidant ndi utoto wa tsitsi.Hydroquinone imapezeka m'mafuta ambiri opaka khungu.
Hydroquinone imagwiritsidwa ntchito pamutu pochiza matenda omwe amadziwika ndi melanin yambiri mu epidermis, monga melasma.Ku United States, mankhwala ounikira khungu osalembedwa ndi dokotala amakhala ndi hydroquinone pamlingo wa 2% kapena kuchepera;ndende zapamwamba zimapezeka ndi mankhwala.
Amagwiritsidwa ntchito kwambiri pojambula, utoto, mphira, mankhwala ophera tizilombo, mankhwala, mankhwala, zoletsa polima, mafakitale a feteleza amafuta desulfurizer, urea synergistic agent, antioxidant, ma reagents osanthula mankhwala.komanso mankhwala ndi utoto intermediates.ndi zapakatikati kwa mankhwala abwino.
Imachititsa mdima pakakhala mpweya ndi kuwala.Zosakanikirana m'madzi.Zothetsera zimakhala zofiirira mumlengalenga chifukwa cha okosijeni.Oxidation imathamanga kwambiri pamaso pa alkali.
Hydroquinone ndi ngozi ya kuphulika pang'ono ikakhudzidwa ndi kutentha.Zosagwirizana ndi ma oxidizing amphamvu.Komanso yosagwirizana ndi maziko.Hydroquinone imachita ndi mpweya ndi sodium hydroxide.Imakhudzidwa ndi mchere wa ferric .NaOH yotentha komanso/kapena yochulukira kwambiri imatha kupangitsa Hydroquinone kuwola mopitilira muyeso pa kutentha kokwezeka.(NFPA Pub. 491M, 1975, 385)
Kukumana ndi hydroquinone mochulukira mwakumwa mwangozi kumabweretsa kawopsedwe komanso poyizoni.Zizindikiro za poyizoni ndi monga, koma si zokhazo, kulankhula mosokonekera, tinnitus, kunjenjemera, kumva kukomoka, kusanza, kugwedezeka kwa minofu, kupweteka mutu, kukomoka, kupuma movutikira ndi cyanosis kuchokera ku methemoglobinemia, chikomokere, ndi kukomoka chifukwa cholephera kupuma.Ogwira ntchito ayenera kuloledwa kugwira ntchito ndi zovala zodzitetezera ndi zophimba fumbi zokhala ndi nkhope zonse kapena magalasi kuti ateteze maso, ndikuyang'aniridwa bwino.
Mtambo wafumbi ukhoza kuphulika ngati utayaka pamalo otsekedwa.Hydroquinone imatha kuchitapo kanthu ndi zinthu zotulutsa oxidizing ndipo imatulutsidwa mwachangu pamaso pa zinthu zamchere.Oxidize mu mpweya.
