Hoʻolauna

ʻO Solvent Red 146 (Solvent Red 146) he mea hui pū me ka inoa kemika 2- [(4-nitrophenyl) methylene] -6-[[4-(trimethylammonium bromide) phenyl] amino] aniline. He mea ʻeleʻele ʻulaʻula pauka, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka waiʻona, ether, ester, etc., hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

Hoʻohana nui ʻia ka Solvent Red 146 ma ke ʻano he kala. Hoʻohana pinepine ʻia no ke kala ʻana i nā textiles, nā fibers a me nā huahana plastic i ka ʻoihana kala.

Hiki iā ia ke hāʻawi i ka mea ʻulaʻula ʻulaʻula, a loaʻa iā ia ke kūpaʻa māmā maikaʻi, ke kūpaʻa wela a me ke kūpaʻa kemika.

ʻano hoʻomākaukau, maʻamau e ka aniline a me ka p-nitrobenzaldehyde a me ʻekolu methyl ammonium bromide reaction. Hiki i nā ʻanuʻu kikoʻī ke kuhikuhi i ka palapala kemika pili.

E pili ana i ka ʻike palekana, ʻo ia ka Solvent he haʻahaʻa haʻahaʻa ka Red 146 ma lalo o nā kūlana hoʻohana maʻamau. Eia nō naʻe, pono e pale ʻia ka inhalation, ka ʻai ʻana a i ʻole ka pili ʻana me ka ʻili a me nā maka no ka mea hiki ke hoʻonāukiuki a me ka naʻau. E noʻonoʻo i nā hana pale pilikino i ka wā e hoʻohana ai, e like me ke komo ʻana i nā mīkina lima, nā maka aniani a me nā lole pale. Inā loaʻa ka pilikia, holoi koke me ka wai a ʻimi i ke kōkua olakino inā pono. Eia kekahi, e mālama i kahi maloʻo a maloʻo, kahi mamao i ke ahi a me nā mea hiki ke ahi.
