● Siv: 1,5-Dihyrdoxynthhalene yog ib nrab ntawm cov khoom siv hluavtaws mordant zo dyes. Nws yog ib qho nruab nrab siv nyob rau hauv cov organic synthesis, chaw muag tshuaj, dyestuff teb thiab kev lag luam duab.
1,5-Dihydroxynthhalene, tseem hu ua Naphthalene-1,5-Diol, yog cov organic sib xyaw nrog cov mis molecular c10h8o2. Nws yog qhov ua rau ntawm Naphthalene, ib lub caij tsheb kauj vab hydrocarbon.1,5-dhihydroxynthhalene yog cov khoom noj dawb lossis daj ntseg hauv cov kuab tshuaj muaj zog zoo li ethanol thiab acetone. Nws muaj ob pawg hydroxyl txuas nrog cov pa roj carbon atoms 1 thiab 5 txoj haujlwm ntawm lub nplhaib naphthalene .Qhov kev sib xyaw ua ke muaj ntau yam kev thov hauv cov khoom siv organic. Nws tuaj yeem raug siv los ua lub tsev thaiv kev npaj rau lwm cov tshuaj, thiab cov poly tshwj xeeb, ethylene terephthalate) (tsiaj) thiab nws cov copolymers. Cov polymers no tau siv dav hauv kev tsim cov fibers, cov duab yeeb yaj kiab, thiab lwm yam khoom siv yas, nws yog ib qho tseem ceeb kom coj 1,5-dhinthhalene nrog kev saib xyuas kom nyab xeeb. Nws raug nquahu kom siv cov khoom tiv thaiv tiv thaiv, ua haujlwm hauv qhov chaw muaj pa zoo, thiab ua raws cov txheej txheem uas tsim nyog thiab pov tseg thaum ua haujlwm nrog cov compound no.
