Taw qhia

Vat txiv kab ntxwv 7, tseem hu ua methylene txiv kab ntxwv, yog cov organic hluavtaws dye. Cov hauv qab no yog cov lus qhia txog qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm Vat Orange 7:

Zoo:

- Cov tsos mob: Vat txiv kab ntxwv 7 yog cov txiv kab ntxwv crystalline hmoov, soluble hauv cawv thiab ketone cov kuab tshuaj, me ntsis soluble hauv dej, thiab cov tshuaj tuaj yeem tau los ntawm cov kuab tshuaj xws li chloroform thiab acetylacetone.

Siv:

- Vat txiv kab ntxwv 7 yog cov organic dye dav siv hauv kev lag luam dye thiab pigment.

- Nws muaj peev xwm xim zoo thiab thermal stability, thiab feem ntau siv hauv textile, tawv, number case, yas thiab lwm yam.

Txoj kev:

- Txoj kev npaj ntawm txo cov txiv kab ntxwv 7 feem ntau yog tau los ntawm reacting nitrous acid thiab naphthalene.

- Nyob rau hauv acidic tej yam kev mob, nitrous acid reacted nrog naphthalene los tsim N-naphthalene nitrosamines.

- Tom qab ntawd, N-naphthalene nitrosamines yog reacted nrog ib tug hlau sulfate tov rau rearrange thiab ua kom txo tau txiv kab ntxwv7.

Cov ntaub ntawv kev nyab xeeb:

- Tsis txhob sib cuag ncaj qha nrog lub qhov muag, tawv nqaij, thiab kab mob ua pa, thiab yaug tam sim ntawd nrog dej kom ntau yog tias muaj kev sib cuag tsis raug.

- Hnav tsom iav thiab hnab looj tes tiv thaiv kom tsis txhob nqus plua plav lossis kev daws teeb meem thaum ua haujlwm.

- Khaws Vat Orange 7 hauv qhov chaw qhuav, txias, kom deb ntawm hluav taws thiab oxidants.
