Hoʻolauna
ʻO ka solvent melemele 33 he mea hoʻoheheʻe kalapona me ka waihoʻoluʻu ʻalani-melemele, a ʻo kona inoa kemika he bromophenol melemele. Loaʻa iā Solvent Yellow 33 nā waiwai penei:
1. Pa'a kala: ho'ohehe'e 'ia ka 'olu'olu melemele 33 i loko o ka solvent organik ma ka lumi wela, e hō'ike ana i ka hopena 'alani-melemele, me ke kūpa'a kala maika'i.
2. Solubility: hiki ke hoʻoheheʻe ʻia ka melemele 33 i loko o nā mea hoʻoheheʻe organik e like me nā ʻawaʻawa, nā ketones, nā esters, nā mea ʻala, a me nā mea ʻē aʻe, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
3. Kū'ē kū'ē kiʻekiʻe: He kiʻekiʻe ka hoʻoheheʻeʻana o ka melemele 33 i loko o nā mea'ūheheʻe a maikaʻi ke kū'ē'ē.
ʻO ka hoʻohana nui ʻana o ka solvent yellow 33 he:
1. Nā puaʻa waiʻona: E like me nā mea hoʻoheheʻe organik, hoʻohana pinepine ʻia ka solvent melemele 33 i nā uhi, inika, plastics, rubber, fibers a me nā māla ʻē aʻe e hāʻawi i nā huahana alani melemele.
2. Dye intermediate: hiki ke hoʻohana ʻia ka solvent yellow 33 ma ke ʻano he intermediate dye, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hoʻohui ʻana i nā mea pena puaʻa ʻē aʻe.
ʻO nā ala maʻamau no ka hoʻomākaukau ʻana i ka solvent yellow 33:
1. Synthesis: hiki ke hoʻomākaukau ʻia ka mea hoʻoheheʻe melemele 33 e ka bromine i ka bromination phenol, a laila acidification, sulfonation, alkylation a me nā ʻano hana like ʻole.
2. ʻO ke ʻano o ka hoʻoheheʻe ʻana: ʻo ka mea maka o ka solvent melemele 33 ua hoʻoheheʻe ʻia me ka oxygen i mua o kahi mea hoʻoheheʻe e hoʻohua ai i ka melemele solvent 33.
ʻO ka ʻike palekana o ka solvent yellow 33 penei:
1. Loaʻa i ka solvent yellow 33 kekahi degere o ka sensitization, hiki ke hoʻoulu i nā hopena maʻi, hopena hoʻonāukiuki i ka ʻili a me nā maka, a pono e hoʻohana i nā mea pale kūpono.
2. I ka wā o ka hoʻohana ʻana, e pale i ka hoʻohu ʻana i ka lepo a i ʻole ka wai o ka solvent melemele 33, a pale i ka pili ʻana me ka ʻili a me nā maka.
3. Inā loa'a ka hui 'ana me ka mea ho'ohehe'e melemele 33, holoi koke i ka wahi i pilikia me ka wai nui.
4. Pono e mālama ʻia ka solvent melemele 33 ma kahi anuanu, maloʻo a me ka makani maikaʻi e pale aku ai i ka hoʻopili ʻana me nā oxidants, acids, alkalis a me nā mea ʻē aʻe.
