Melemele 18 CAS 6407-78-9

Hoʻolauna

ʻO Solvent Yellow 18 he mea hoʻoheheʻe organik me ka inoa kemika o 2-chloro-1,3,2-dibenzothiophene.

Loaʻa iā Solvent Yellow 18 nā waiwai penei:

1. Nani: melemele crystalline pauda paʻa;

4. Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe polar organic, e like me ka ethanol, ethers a me nā hydrocarbons chlorinated.

Nā hoʻohana nui o ka solvent yellow 18:

1. Ma keʻano he kala waena: hiki ke hoʻohana ʻia ka solvent melemele 18 i ka synthesis o nā kala, a he hana koʻikoʻi i ka pena ʻana i nā lole, pepa a i ʻole nā ​​​​huahana plastik;

2. Ma keʻano he mea hoʻoheheʻe: Loaʻa iā ia ka solubility maikaʻi a hiki ke hoʻohanaʻia ma keʻano he mea hoʻoheheʻe i nā hanana synthesis.

ʻO ke ʻano o ka hoʻomākaukau ʻana o ka solvent melemele 18:

Hiki ke hoʻokumu ʻia ka mea hoʻoheheʻe melemele 18 e ka hopena o benzothiophene me ka chloroacetyl chloride, a laila loaʻa i ka hana catalytic o ka cuprous chloride a me ka iridium carbonate.

ʻIke palekana o Solvent Yellow 18:

1. Loaʻa i ka solvent yellow 18 kekahi ʻano ʻino a me nā mea ʻawaʻawa, hiki ke hoʻonāukiuki a me ka ʻoluʻolu i ka pili ʻana me ka ʻili a me ka inhalation;

2. Pono e mālama ʻia e pale aku i ka pili ʻana me ka ʻili a me nā maka i ka wā e hoʻohana ai, a e hōʻoia i ka hana ʻia ʻana o ka hana ma kahi wahi hoʻoluʻu maikaʻi;

3. Inā pili ka ʻai ʻana a i ʻole ka ʻai ʻana, e holoi koke me ka wai nui a e ʻimi i ka lāʻau lapaʻau i ka manawa;

4. I ka wā e mālama ai, pono e hoʻopaʻa ʻia a hoʻopaʻa ʻia i kahi maloʻo maloʻo e pale aku i ka hoʻopili ʻana me nā oxidants ikaika a me nā waikawa ikaika.
