Taw qhia

1,1′-[(phenylmethylene)bis[(2-methoxy-4,1-phenyl)azo]] di-2-naphthol, tseem hu ua AO60, yog cov organic hluavtaws dye. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:

 

Khoom: AO60 yog daj mus rau liab-xim av crystalline hmoov, insoluble nyob rau hauv dej, soluble nyob rau hauv organic solvents xws li methanol, ethanol thiab chloroform. Nws ruaj khov nyob rau hauv acidic, nruab nrab thiab alkaline tej yam kev mob.

 

Kev Siv: AO60 feem ntau yog siv los ua cov xim thiab qhov taw qhia. Nws tuaj yeem siv los ua tus neeg sawv cev dyeing rau textiles, tshwj xeeb tshaj yog rau cov nyhuv dyeing ntawm ntuj fibers xws li paj rwb thiab linen. Nws kuj tseem siv tau rau xim yas thiab roj hmab. Nws kuj tseem siv tau los ua cov ntsuas acid-puag thiab rau kev txiav txim siab pH.

 

Txoj kev npaj: Qhov kev npaj ntawm AO60 feem ntau yog tau los ntawm kev sib txuas cov tshuaj tiv thaiv ntawm nitrous acid thiab styrene, thiab tom qab ntawd reacted nrog 2-naphthol los tsim cov khoom lag luam.
