I-Hydroquinone (HQ) (i-CAS: 123-31-9) ikhiqizwa yi-oxidation ye-aniline noma i-phenol, ngokunciphisa i-quinone, noma ngokusabela kwe-acetylene ne-carbon monoxide.
IHydroquinone i-ejenti yokunciphisa esetshenziswa kumthuthukisi wezithombe, eyenza i-polymerize phambi kwama-oxidizing agents.Embonini yokukhiqiza ingase yenzeke ihlanganisa i-bacteriostatic ejenti, izidakamizwa, ukucutshungulwa koboya, uphethiloli wemoto, upende, amakhemikhali emvelo, amapulasitiki, okokumboza ngamatshe, nama-styrene monomers.
Sebenzisa njengesinciphisi sezithombe kanye nonjiniyela;njenge-reagent ekunqumeni amanani amancane we-phosphate;njenge-antioxidant.I-Depigmentor.
Isinciphisi sezithombe kanye nonjiniyela;i-antioxidant;i-ejenti yokuzinzisa kwamanye ama-polymer;okuphakathi ekwenziweni kwabathile odayi nezingulube;ekwenziweni kwezimonyo.
IHydroquinone isetshenziswa kubathuthukisi bezithombe (abamnyama nabamhlophe, ama-X-ray, nama-microfilm), kumapulasitiki, kumadayi ezinwele njengesithako esivikela ukuvikela kanye nombala wezinwele.IHydroquinone itholakala kumakhilimu amaningi okugcoba isikhumba.
IHydroquinone isetshenziswa phezulu ekwelapheni izifo ezibonakala nge-melanin eyeqile ku-epidermis, njenge-melasma.E-United States, imikhiqizo engagunyaziwe yokukhanyisa isikhumba iqukethe i-hydroquinone ekugxilweni kuka-2% noma ngaphansi;ukugxila okuphezulu kuyatholakala ngencwadi kadokotela.
Isetshenziswa kakhulu ezithombeni, odayi, irabha, izibulala-zinambuzane, amakhemikhali, imithi, i-polymer inhibitors, imboni kamanyolo kamanyolo desulfurizer, i-urea synergistic agent, antioxidant, chemical analysis reagents.futhi intermediate imithi kanye nodayi.futhi kuphakathi kwamakhemikhali amahle.
Yenza kube mnyama ekuchayekeni emoyeni nasekukhanyeni.Ingxube emanzini.Izixazululo ziba nsundu emoyeni ngenxa ye-oxidation.I-oxidation ishesha kakhulu lapho kukhona i-alkali.
IHydroquinone iyingozi yokuqhuma kancane lapho ichayeke ekushiseni.Akuhambisani nama-oxidizing agents aqinile.Futhi akuhambisani nezisekelo.I-Hydroquinone ihlangana ne-oxygen ne-sodium hydroxide.Isabela ngosawoti we-ferric .I-NaOH eshisayo kanye/noma egxilile ingabangela i-Hydroquinone ukuthi ibole ngendlela exakile ezingeni lokushisa eliphakeme.(NFPA Pub. 491M, 1975, 385)
Ukuchayeka ku-hydroquinone ngobuningi ngokuyiphuza ngomlomo ngephutha kukhiqiza ubuthi kanye nobuthi.Izimpawu zobuthi zihlanganisa, kodwa azigcini nje lapho, inkulumo elufifi, i-tinnitus, ukuvevezela, ukuzwa ukumibilika, ukuhlanza, ukudikiza kwemisipha, ikhanda elibuhlungu, ukudlikizeka, ukuphelelwa umoya kanye ne-cyanosis evela ku-methemoglobinemia, ikhoma, kanye nokuwa ngenxa yokwehluleka ukuphefumula.Izisebenzi zasemsebenzini kufanele zivunyelwe ukusebenza ngezingubo zokuzivikela kanye nezifihlabuso zothuli ezinobuso obugcwele noma izibuko zokuvikela amehlo, nangaphansi kokuphathwa okufanele.
Ifu lothuli lingase liqhume uma livutha endaweni evalekile.I-Hydroquinone ingasabela ngezinto ezi-oxidizing futhi ikhishwa nge-oxid ngokushesha lapho kukhona izinto ezine-alkali.I-Oxidize emoyeni.
