Keʻokeʻo hina a ʻulaʻula a i ʻole ka pulp. Ua loaʻa ka sodium m-aminobenzene sulfonate ma o ka sulfonation reaction o nitrobenzene a me ka ho'ēmi. Hoʻohana ʻia no ka hana ʻana i nā dyes azo a me nā intermediates pharmaceutical, reactive, acidic, sulfide a me nā mea ʻē aʻe.

HIKI METANILICKA PAAKAI SODIUMA

英文 名词: m-aminobenzenesulfonic ACID SODIUM SALT; SODIUM METANILATE.

CAS no. : 1126-34-7

EINECS Helu : 214-419-3 [1]

Kumu molekala: C6H6NNaO3S

Kaumaha molekula: 195.1734

ʻAno: Keʻokeʻo hina a hiki i ke aniani ʻulaʻula māmā a i ʻole slurry

Keokeo maikai keokeo. ʻO ka mahana decomposition o ke aniani i loaʻa mai ka wai he 302 ~ 304 ℃.

ʻakika Metaniliche keʻokeʻo hina a ʻulaʻula paha ke ʻano he crystalline a i ʻole slurry

Ka huina amino, % ≥60

Maikaʻi, % ≥90

Maʻiʻo o ka mea hiki ʻole ke hoʻoheheʻe ʻia i loko o ka soda, % ≤1.5

Hoʻohana: hoʻohana ʻia i ka hana ʻana i nā dyes azo a me nā intermediates pharmaceutical, reactive, acid, sulfide a me nā mea ʻē aʻe.

ʻO ke ala kaʻina hana: lawe ʻia ka hopena sulfonation o ka nitrobenzene a me ka fuming sulfuric acid ma 115 ℃, a ua hoʻokaʻawale ʻia ka hopena hopena i ka neutral e ka wai alkali, a laila kānana ka hopena sodium o m-nitrobenzene sulfonate. Ua hoʻemi ʻia ka haʻina me nā kohu hao ma ke ʻano he catalyst e loaʻa ai ka m-aminobenzene sulfonate, a ua wehe ʻia ka lepo hao ma ka kānana ʻana. ʻO ka filtrate ka wai paʻakai m-aminobenzene sulfonate. E hoʻohui i ka sulfuric acid i loko o ka ipu hao a hiki i ka ʻulaʻula o Congo pepa hōʻike ʻulaʻula, a mālama i ka mahana ma 70 ℃. A laila, loaʻa ka m-aminobenzene sulfonate slurry ma ka kānana centrifugation.

ʻO ka ʻawaʻawa a me ka pale: he mea ʻawaʻawa kēia huahana. ʻO ka ʻai ʻana a i ʻole ke komo ʻana i loko o ka ʻili hiki ke hoʻomake nui. Eia naʻe, ʻoi aku ka liʻiliʻi o kona ʻona ma mua o ka aniline, ʻaʻole ia e hoʻoulu i ka hopena carcinogenic. I ka wā o ke kaʻina hana, pono e pale ʻia mai ka ʻaʻahu ʻole ʻana a i ʻole ka pīpī ʻana i ka ʻili, pono e hoʻopaʻa ʻia nā mea hana e pale ai i ka leakage, a pono ka mea hoʻohana e hoʻokomo i nā mea pale.

Hoʻopili a mālama ʻia: mālama i kahi ʻoluʻolu, ventilated a maloʻo, pale i ka wela, ka maʻa a me ka lā. E mālama a lawe ʻia e like me nā lula o nā mea ʻona.
