Taw qhia

Benzoazobenzoazo-2-naphthol feem ntau yog siv los ua xim hauv kev lag luam xws li textiles, inks thiab plastics. Nws tuaj yeem siv los zas cov ntaub ntawv fiber ntau xws li paj rwb, linen, wool, thiab lwm yam. Nws cov xim ruaj khov yog qhov zoo thiab tsis yooj yim rau ploj, yog li nws tau siv dav hauv kev lag luam textiles.

 

Cov txheej txheem ntawm kev npaj benzoazobenzobenzo-azo-2-naphthol feem ntau yog ua los ntawm azo cov tshuaj tiv thaiv. Aniline yog thawj zaug reacted nrog nitric acid los tsim nitroaniline, thiab tom qab ntawd reacted nrog naphtholl los tsim cov khoom lag luam, benzoazobenzo-azo-2-naphthol.

 

Kev nyab xeeb cov ntaub ntawv hais txog benzoazobenzenezo-2-naphthol, nws yog cov khoom siv hluav taws xob thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua, kom deb ntawm qhov hluav taws kub thiab qhov kub thiab txias. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes (lab) hnab looj tes, tsom iav kev nyab xeeb, thiab cov tsho tiv thaiv yuav tsum hnav thaum ua haujlwm. Raws li nws yog ib qho tshuaj, cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm thiab cov txheej txheem pov tseg yuav tsum ua raws.
