Hoʻolauna

Pigment melemele 138, ʻike ʻia hoʻi he melemele pua maka, pū melemele, inoa kemika ʻo 2,4-dinitro-N-[4-(2-phenylethyl)phenyl]aniline. ʻO kēia ka hoʻolauna ʻana i kekahi o nā waiwai, hoʻohana, hana hana a me ka ʻike palekana o Yellow 138:

ʻAno maikaʻi:

- ʻO ka melemele 138 he pauka crystalline melemele, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik, e like me ka methanol, ethanol, etc., a hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

- ʻO kāna hana kemika e hoʻoholo ai i ka photostability maikaʻi a me ka pale wela.

- He kūpaʻa maikaʻi ka melemele 138 ma lalo o nā kūlana ʻawaʻawa, akā hiki ke wehe ʻia ma lalo o nā kūlana alkaline.

E hoʻohana:

- Hoʻohana nui ʻia ka melemele 138 ma ke ʻano he puaʻa kūlohelohe a hoʻohana nui ʻia i nā pena, nā inika, nā plastics a me nā ʻoihana ʻē aʻe.

- Ma muli o kona waihoʻoluʻu melemele a me ka wikiwiki o ka waihoʻoluʻu maikaʻi, hoʻohana pinepine ʻia ʻo Yellow 138 ma ke ʻano he puaʻa i ka pena aila, pena pena wai, pena acrylic a me nā kiʻi ʻē aʻe.

Hanana:

- ʻOi aku ka paʻakikī o ka hoʻomākaukau ʻana o ka melemele 138, a loaʻa pinepine ʻia e ka hopena oxidation me nā pūhui amino.

- Hiki i ke ala hoʻomākaukau kūikawā ke komo i ka hopena o nā pūhui nitroso me ka aniline e loaʻa ai ka 2,4-dinitro-N-[4-(2-phenylethyl)phenyl] imine, a laila ka hopena o ka imine me ke kālā hydroxide e hoʻomākaukau ai iā Huang 138 .

ʻIke palekana:

- Manaʻo ʻia ka melemele 138 he paʻa a palekana ma lalo o nā kūlana hoʻohana maʻamau.

- Hiki i ka melemele 138 ke wehe i ka waihoʻoluʻu ma lalo o nā kūlana alkaline, no laila e pale ʻia ka hoʻopili ʻana me nā mea alkaline.
