Isicelo

IHydroquinone iyi-ejenti ekhanyisa umbala esetshenziswa kumakhilimu amhlophe. I-Hydroquinone ihlangana nomoya-mpilo ngokushesha kakhulu futhi iba nsundu lapho ichayeke emoyeni. Nakuba kwenzeka ngokwemvelo, inguqulo yokwenziwa iyona evame ukusetshenziswa ezimonyoni. Ukufakwa esikhumbeni kungase kubangele ukungezwani komzimba futhi kwandise isikhumba ukuzwela ilanga. IHydroquinone inamandla okwenza umdlavuza futhi ihlotshaniswa nokubangela i-ochronosis, ukuguga kwesikhumba. I-US FDA ivimbele i-hydroquinone ekwenziweni kwezimonyo kwe-oTC, kodwa ivumela amaphesenti angu-4 emikhiqizweni kadokotela.

I-1,4-dihydroxybenzene, eyaziwa nangokuthi i-hydroquinone, iyikhemikhali ebalulekile yezinto ezingavuthiwe. Ukubukeka kwayo kuyikristalu e-acicular emhlophe. I-1,4-dihydroxybenzene isetshenziswa kakhulu njengento ebalulekile, ephakathi nendawo futhi eyisizayo emithini, izibulala-zinambuzane, odayi kanye nenjoloba. Isetshenziswa kakhulu njengonjiniyela, udayi we-anthraquinone, udayi we-azo, irabha antioxidant kanye ne-monomer polymerization inhibitor, i-stabilizer yokudla kanye ne-coating antioxidant, i-petroleum anticoagulant, i-synthetic ammonia catalyst, njll. Ingasetshenziswa futhi njenge-reagent yokuhlaziya, i-ejenti yokunciphisa kanye nomthuthukisi wethusi. negolide.
