Pigment Samasama 138 CAS 30125-47-4
Folasaga
Pigment samasama 138, e lauiloa foi o le fuga lanu samasama, pu samasama, igoa vailaʻau o le 2,4-dinitro-N-[4-(2-phenylethyl)phenyl]aniline. O lo'o taua i lalo se fa'amatalaga i nisi o meatotino, fa'aoga, auala gaosiga ma fa'amatalaga saogalemu a Yellow 138:
Tulaga lelei:
- Lanu samasama 138 o se paʻu tioata samasama, lea e faigofie ona solu i solu faʻaletino, e pei o le methanol, ethanol, ma isi, ma e le mafai ona solu i le vai.
- O lona fausaga kemikolo e iloa ai e lelei le photostability ma le vevela.
- Lanu samasama 138 e lelei le mautu i lalo o tulaga oona, ae e faigofie ona faʻafefe i lalo o tulaga alkaline.
Fa'aaogā:
- Lanu samasama 138 e masani ona faʻaaogaina e avea o se vailaʻau faʻasolosolo ma e faʻaaogaina lautele i vali, vaitusi, palasitika ma isi pisinisi.
- Ona o lona lanu samasama manino ma le vave lanu lanu, Yellow 138 e masani ona faʻaaogaina e fai ma pigmenti i le suauʻu vali, vali vai, vali vali ma isi faʻataʻitaʻiga.
Metotia:
- O le sauniuniga o le samasama 138 e sili atu ona faigata, ma e masani lava ona maua e ala i le faʻamaʻiina o faʻamaʻi ma mea amino.
- O le auala faʻapitoa sauniuni e mafai ona aofia ai le tali atu o mea faʻapipiʻi nitroso ma le aniline e maua ai le 2,4-dinitro-N-[4-(2-phenylethyl)phenyl] imine, ona sosoo ai lea ma le tali atu o le imine ma le hydroxide siliva e saunia ai Huang 138 .
Fa'amatalaga Saogalemu:
- Samasama 138 e masani ona manatu e mautu ma saogalemu i lalo ole fa'aoga masani.
- Lanu samasama 138 e faigofie ona liu lanu i lalo o tulaga alkaline, o lea e tatau ona aloese mai le faʻafesoʻotaʻi ma mea alkaline.
