Toxicity LD50 qhov ncauj hauv nas: 320 mg/kg (Woodard)
Hydroquinone (HQ) (CAS: 123-31-9) yog tsim los ntawm oxidation ntawm aniline lossis phenol, los ntawm kev txo qis ntawm quinone, lossis los ntawm cov tshuaj tiv thaiv ntawm acetylene thiab carbon monoxide.
Hydroquinone yog ib tug txo tus neeg sawv cev siv nyob rau hauv ib tug yees duab tsim, uas polymerizes nyob rau hauv lub xub ntiag ntawm oxidizing agents.Hauv kev lag luam kev lag luam nws tuaj yeem tshwm sim suav nrog tus neeg sawv cev bacteriostatic, tshuaj, kev ua plaub, roj cav, xim, organic chemicals, plastics, pob zeb txheej, thiab styrene monomers.
Siv raws li kev yees duab reducer thiab tsim tawm;raws li reagent nyob rau hauv kev txiav txim ntawm me me ntawm phosphate;raws li antioxidant.Depigmentor.
Kev yees duab reducer thiab tsim tawm;antioxidant;stabilizing tus neeg sawv cev rau qee cov polymers;nruab nrab hauv kev tsim khoom ntawm qee cov dyes thiab pigments;nyob rau hauv cov tshuaj pleev ib ce formulations.
Hydroquinone yog siv nyob rau hauv kev yees duab developers (dub thiab dawb, X-ray, thiab microfilms), nyob rau hauv yas, nyob rau hauv cov plaub hau dyes raws li ib tug antioxidant thiab plaub hau colorant.Hydroquinone muaj nyob rau hauv ntau daim tawv nqaij bleaching cream.
Hydroquinone yog siv tshuaj pleev ib ce los kho cov teeb meem uas tshwm sim los ntawm ntau heev melanin nyob rau hauv epidermis, xws li melasma.Hauv Tebchaws Meskas, cov khoom siv tshuaj pleev xim rau cov tawv nqaij tsis muaj tshuaj muaj hydroquinone ntawm qhov ntau ntawm 2% lossis tsawg dua;ntau dua concentration yog muaj los ntawm cov tshuaj.
Dav siv nyob rau hauv kev yees duab, dyes, roj hmab, tshuaj tua kab, tshuaj, tshuaj, polymer inhibitors, tshuaj chiv kev lag luam desulfurizer, urea synergistic tus neeg saib xyuas, antioxidant, tshuaj ntsuam xyuas reagents.kuj tseem siv tshuaj thiab dye intermediates.thiab nruab nrab rau cov tshuaj zoo.
Darkens ntawm raug huab cua thiab lub teeb.Miscible hauv dej.Cov tshuaj ua xim av hauv huab cua vim oxidation.Oxidation yog ceev heev nyob rau hauv lub xub ntiag ntawm alkali.
Hydroquinone yog qhov tawg me ntsis thaum raug tshav kub.Incompatible nrog muaj zog oxidizing neeg sawv cev.Kuj incompatible nrog bases.Hydroquinone reacts nrog oxygen thiab sodium hydroxide.Reacts nrog ferric ntsev.Kub thiab / lossis concentrated NaOH tuaj yeem ua rau Hydroquinone decompose exothermically ntawm qhov kub siab.(NFPA Pub. 491M, 1975, 385)
Kev nthuav tawm rau hydroquinone ntau ntau los ntawm kev sib tsoo ntawm qhov ncauj ua rau muaj tshuaj lom thiab lom.Cov tsos mob ntawm kev lom muaj xws li, tab sis tsis txwv rau, tsis meej pem, hais lus tsis meej, tinnitus, tshee, hnov tsw, ntuav, leeg twitching, mob taub hau, convulsions, dyspnea thiab cyanosis los ntawm methemoglobinemia, coma, thiab vau los ntawm kev ua pa tsis ua haujlwm.Cov neeg ua haujlwm ua haujlwm yuav tsum raug tso cai ua haujlwm nrog cov khaub ncaws tiv thaiv thiab plua plav qhov ncauj qhov ntswg nrog lub ntsej muag lossis tsom iav los tiv thaiv qhov muag, thiab nyob rau hauv kev tswj kom raug.
Plua plav huab yuav tawg yog tias ignited nyob rau hauv ib cheeb tsam uas nyob ib puag ncig.Hydroquinone tuaj yeem hnov mob nrog oxidizing cov ntaub ntawv thiab yog oxidized sai heev nyob rau hauv lub xub ntiag ntawm alkaline cov ntaub ntawv.Oxidizes hauv huab cua.
