Taw qhia

Solvent Yellow 43 yog cov kuab tshuaj organic nrog lub npe tshuaj ntawm Pyrrole Sulfonate Yellow 43. Nws yog cov hmoov daj tsaus uas yaj hauv dej.

 

Cov kuab tshuaj daj 43 feem ntau yog siv los ua xim xim, xim thiab fluorescent sojntsuam.

 

Muaj ntau txoj hauv kev los npaj cov kuab tshuaj daj 43, ib qho ntawm cov tshuaj tiv thaiv 2-ethoxyacetic acid nrog 2-aminobenzene sulfonic acid hauv ketone hnyav, thiab tau txais cov khoom kawg los ntawm acidification, nag lossis daus, ntxuav thiab ziab.

Nws yog ib qho organic compound uas muaj qee yam toxicity thiab tuaj yeem ua rau khaus thiab ua xua nyob rau hauv kev sib cuag nrog daim tawv nqaij los yog nqus tau nws cov plua plav. Hnav cov hnab looj tes tiv thaiv thiab tsom iav thaum ua haujlwm, thiab xyuas kom meej tias nws tau ua nyob rau hauv qhov chaw muaj cua zoo. Tsis tas li ntawd, tsis txhob sib xyaw nrog cov tshuaj xws li oxidants thiab acids muaj zog kom tsis txhob muaj tshuaj lom neeg thiab tsim kev phom sij.
