I-Hydroquinone (HQ) (i-CAS: i-123-31-9) iveliswa yi-oxidation ye-aniline okanye i-phenol, ngokunciphisa i-quinone, okanye ukuphendulwa kwe-acetylene kunye ne-carbon monoxide.
IHydroquinone yiarhente yokunciphisa esetyenziswa kumphuhlisi weefoto, ezenza iipolymerize kubukho bee-oxidizing agents.Kwishishini lokuvelisa inokuthi yenzeke ibandakanya i-bacteriostatic agent, iziyobisi, ukusetyenzwa koboya, i-motor fuel, ipeyinti, iikhemikhali eziphilayo, iiplastiki, i-coating yamatye, kunye ne-styrene monomers.
Sebenzisa njengokunciphisa iifoto kunye nomphuhlisi;njenge-reagent ekumiselweni kwee-phosphates ezincinci;njenge-antioxidant.I-Depigmentor.
Isinciphisi sefoto kunye nomphuhlisi;antioxidant;i-arhente yokuzinzisa kwezinye iipolymers;esiphakathi ekwenzeni ezinye iidayi kunye nebala;kwiinkqubo zokuthambisa.
IHydroquinone isetyenziswa kubaphuhlisi bokufota (abamnyama namhlophe, iX-reyi, kunye nemicrofilm), kwiiplastiki, kwiidayi zeenwele njenge-antioxidant kunye nombala weenwele.IHydroquinone ifumaneka kwiikhrimu ezininzi zokuthambisa ulusu.
IHydroquinone isetyenziswa ngokwesihloko ukunyanga iziphazamiso eziphawulwa ngokugqithisileyo kwe-melanin kwi-epidermis, njenge-melasma.EUnited States, iimveliso ezikhanyisa ulusu ezingabhalwanga ziqulethe i-hydroquinone ekugxininiseni kwe-2% okanye ngaphantsi;ugxininiso oluphezulu lufumaneka ngomyalelo.
Isetyenziswa kakhulu ukufota, idayi, irabha, izibulali zinambuzane, iikhemikhali, iyeza, i-polymer inhibitors, i-desulfurizer ye-chemical fertilizer, i-urea synergistic agent, i-antioxidant, i-reagents yohlalutyo lweekhemikhali.kwakhona amayeza kunye nedayi intermediates.kunye nephakathi kwiikhemikhali ezilungileyo.
Kwenza kube mnyama xa kutyhileke emoyeni nasekukhanyeni.Ingxubevange emanzini.Izisombululo ziba mdaka emoyeni ngenxa ye-oxidation.I-oxidation ikhawuleza kakhulu xa kukho i-alkali.
IHydroquinone yingozi yokudubula kancinane xa ibekwe kubushushu.Ayihambelani ne-oxidizing agents ezinamandla.Kananjalo ayihambelani neziseko.IHydroquinone idibana neoksijini kunye nesodium hydroxide.Isabela ngeetyuwa ezineferrikhi .I-NaOH eshushu kunye/okanye igxile kunokubangela ukuba iHydroquinone ibole ngokugqithisileyo kubushushu obuphezulu.(NFPA Pub. 491M, 1975, 385)
Ukutyhileka kwi-hydroquinone ngobuninzi obukhulu ngokusela ngomlomo ngempazamo kuvelisa ubutyhefu kunye netyhefu.Iimpawu zetyhefu ziquka, kodwa aziphelelanga apho, intetho engacacanga, i-tinnitus, ukungcangcazela, ukufuthaniselwa, ukugabha, ukuxhuzula kwemisipha, intloko ebuhlungu, ukuxhuzula, ukuphelelwa umoya kunye ne-cyanosis evela kwi-methemoglobinemia, isiqaqa, kunye nokuwa ngenxa yokungaphefumli kakuhle.Abasebenzi basemsebenzini kufuneka bavunyelwe basebenze ngempahla ekhuselayo kunye neemaski zothuli ezinobuso obugcweleyo okanye iiglasi ukukhusela amehlo, kwaye phantsi kolawulo olululo.
Ilifu lothuli linokudubula ukuba lithe lavutha kwindawo evalelweyo.I-Hydroquinone inokusabela ngezixhobo ze-oxidizing kwaye i-oxidized ngokukhawuleza kubukho bezinto ze-alkaline.I-Oxidizes emoyeni.
