Taw qhia

4-Amino-N-2,4-xylyl-1, 8-napthalimide, tseem hu ua Sultan gills, yog cov organic hnyav dye. Hauv qab no yog cov lus piav qhia ntawm cov khoom, kev siv, kev npaj thiab kev nyab xeeb ntawm 4-Amino-N-2,4-xylyl-1, 8-napthalimide:

Xwm:

4-Amino-N-2,4-xylyl-1, 8-napthalimide yog xim daj daj crystalline hmoov uas tsis yooj yim soluble hauv dej tab sis soluble hauv cov kuab tshuaj organic xws li ethers, olefins thiab cawv. Nws muaj kev ruaj ntseg zoo thiab lub teeb ua haujlwm.

Siv:

4-Amino-N-2,4-xylyl-1, 8-napthalimide feem ntau yog siv los ua xim xim rau sab hauv thiab sab nraum zoov pigments, inks thiab plastics. Nws tseem tuaj yeem siv rau dyeing cov ntaub ntawv xws li textiles, tawv thiab ntawv. Nws yog xim daj tsaus los muab lub zog zais zoo thiab xim ruaj khov.

Txoj kev:

4-Amino-N-2,4-xylyl-1, 8-napthalimide yog tau los ntawm cov tshuaj synthesis. Ib txoj kev siv hluavtaws feem ntau yog cov tshuaj tiv thaiv ntawm p-toluidine thiab aniline tov nrog sulfur kom muab 4-Amino-N-2,4-xylyl-1, 8-napthalimide crystals nyob rau hauv acidic tej yam kev mob.

Cov ntaub ntawv kev nyab xeeb:

4-Amino-N-2,4-xylyl-1, 8-napthalimide kuj muaj kev nyab xeeb nyob rau hauv kev siv dav dav, tab sis cov teeb meem hauv qab no tseem yuav tsum tau saib xyuas:

1. Thaum siv, yuav tsum tsis txhob sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag. Thaum muaj kev sib cuag, yaug tam sim nrog dej ntau thiab nrhiav kev kho mob.

2. Tsis txhob nqus cov 4-Amino-N-2,4-xylyl-1, 8-napthalimide hmoov lossis roj. Siv rau hauv qhov chaw uas muaj cua zoo thiab hnav cov khoom tiv thaiv tsim nyog (xws li lub npog ntsej muag).

3. Kev khaws cia yuav tsum tsis txhob sib cuag nrog cov khoom siv hluav taws xob tiv thaiv hluav taws los yog tawg.

4. Yog tias koj muaj lus nug lossis muaj xwm txheej ceev, thov xa mus rau daim ntawv qhia kev nyab xeeb ntawm cov ntaub ntawv uas cuam tshuam lossis nrog tus kws tshaj lij.
