2-Hydroxy-1,4-naphthoquinone Alias: Lausoquinone, Scattered Foam Quinone, Henna Quinone, 2-Hydroxy, 4-Naphthalenedione, Lauson Yellow, 2-Hydroxy-p-naphthoquinone.
2-Hydroxy-1,4-naphthoquinone yog ib qho organic compound uas muaj hydroxyl thiab quinone pawg nyob rau hauv ib tug ci daj los yog txiv kab ntxwv crystal daim ntawv. Lub compound yog ruaj khov nyob rau hauv chav tsev kub tab sis yog flammable thiab incompatible nrog muaj zog oxidizing agents, yog li yuav tsum tau saib xyuas tshwj xeeb rau kev nyab xeeb nyob rau hauv cia thiab siv.
Ib txoj hauv kev ntawm kev npaj yog cov tshuaj tiv thaiv ntawm ammonium 1,2-naphthoquinone-4-sulfonate thiab sulfur hauv methanol kom muab methoxynaphthoquinone, uas tom qab ntawd hydrolyzed nrog sodium hydroxide thaum kawg muab 2-hydroxy-1,4-naphthoquinone. Cov txiaj ntsig ntawm txoj kev no tuaj yeem ncav cuag 58-65%.
Raws li naphthoquinone dye, 2-hydroxy-1,4-naphthoquinone yog siv dav hauv kev npaj cov plaub hau dyes thiab textile dyes vim nws cov xim ci thiab zoo dyeing zog. Lub kaw lus conjugated hauv nws cov molecule ua rau cov dye molecule muaj lub zog nqus spectrum thiab tuaj yeem nthuav tawm cov xim ci hauv qhov pom ntau yam.
2-Hydroxy-1,4-naphthoquinone muaj peev xwm tiv thaiv kab mob thiab muaj peev xwm tiv thaiv lossis tua kev loj hlob ntawm qee yam kab mob. Yog li ntawd, nyob rau hauv lub chaw ua tshuaj, nws yog feem ntau siv raws li ib tug constituent ntawm bactericidal agents rau kev npaj cov khoom uas muaj bactericidal thiab tshuaj tua kab mob. Tsis tas li ntawd, lub compound muaj qee yam antioxidant zog thiab tuaj yeem siv rau kev tiv thaiv antioxidant ntawm cov tshuaj molecules.
Vim nws cov khoom siv tshuaj tshwj xeeb, 2-hydroxy-1,4-naphthoquinone tuaj yeem siv los ntes cov ntiv tes latent ntawm daim ntawv. Thaum cov khoom sib xyaw ua ke nrog qee yam tshuaj lom neeg ntawm cov ntiv tes, nws ua rau pom kev hloov xim, uas pab tshawb nrhiav thiab txheeb xyuas cov ntiv tes. Cov cuab yeej no muaj cov ntawv thov tseem ceeb hauv thaj chaw xws li kev tshawb nrhiav kev ua txhaum cai thiab kev txheeb xyuas cov ntaub ntawv.
