Taw qhia

Pigment yellow 138, tseem hu ua raw paj daj, daj trumpet, tshuaj lub npe yog 2,4-dinitro-N-[4-(2-phenylethyl)phenyl]aniline. Cov hauv qab no yog kev qhia txog qee yam ntawm cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb ntawm Yellow 138:

Zoo:

- Yellow 138 yog cov hmoov crystalline daj, uas yooj yim soluble hauv cov kuab tshuaj organic, xws li methanol, ethanol, thiab lwm yam, thiab insoluble hauv dej.

- Nws cov qauv tshuaj txiav txim siab tias nws muaj qhov zoo photostability thiab kub tsis kam.

- Yellow 138 muaj kev ruaj ntseg zoo nyob rau hauv acidic tej yam kev mob, tab sis nws yog nquag mus rau discoloration nyob rau hauv alkaline tej yam kev mob.

Siv:

- Yellow 138 feem ntau yog siv los ua cov organic pigment thiab yog siv dav hauv cov xim, inks, plastics thiab lwm yam lag luam.

- Vim nws cov xim daj zoo nkauj thiab cov xim zoo nkauj, Yellow 138 feem ntau yog siv los ua cov xim hauv cov roj pleev xim, pleev xim dej, pleev xim acrylic thiab lwm yam kev kos duab.

Txoj kev:

- Txoj kev npaj ntawm daj 138 yog qhov nyuaj dua, thiab nws feem ntau tau txais los ntawm oxidation cov tshuaj tiv thaiv nrog cov amino tebchaw.

- Txoj kev npaj tshwj xeeb yuav suav nrog cov tshuaj tiv thaiv ntawm nitroso tebchaw nrog aniline kom tau 2,4-dinitro-N-[4-(2-phenylethyl)phenyl] imine, thiab tom qab ntawd cov tshuaj tiv thaiv ntawm imine nrog silver hydroxide los npaj Huang 138 .

Cov ntaub ntawv kev nyab xeeb:

- Yellow 138 feem ntau suav tias yog qhov ruaj khov thiab muaj kev nyab xeeb raws li kev siv ib txwm siv.

- Yellow 138 yog qhov ua rau tsis muaj xim nyob rau hauv cov xwm txheej alkaline, yog li kev sib cuag nrog cov tshuaj alkaline yuav tsum raug zam.

Yav dhau los: Pigment Yellow 110 CAS 5590-18-1 / 106276-80-6
