4,4′-Oxydianiline me CAS 101-80-4
ʻO 4,4-diaminodiphenyl Ether (4'-ODA) CAS 101-80-4,4,4' -oxydianiline kahi hui organik diamine ʻala koʻikoʻi. Ma muli o ke alo o ʻelua mau hui amino (-NH₂) a me hoʻokahi pilina ether (-O-) i loko o kāna molekala, loaʻa iā 4,4'-DPE ka reactivity maikaʻi loa a me ke kūpaʻa wela a he monomer koʻikoʻi ia no ka hana ʻana i nā mea polymer hana kiʻekiʻe.
Ma ke ʻano he mea ʻenekinia kūikawā, loaʻa i ka polyimide nā pono o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa i ka radiation a me ka ikaika mechanical kiʻekiʻe. Hoʻohana ʻia ka diaminodiphenyl ether i nā kiʻiʻoniʻoni, nā uhi, nā fibers, aerospace, nā ʻoihana uila a me nā uila, nā plastics foamed a me nā photoresists. ʻO 4,4'-Diaminodiphenyl ether kekahi o nā mea maka nui. I ka manawa like, hiki ke hoʻohana ʻia ka 4,4'-diaminodiphenyl ether e hana i ka mea hoʻopili cross-linking, a hoʻohana nui ʻia e pani i ka benzidine carcinogenic e hana i nā dyes azo a me nā dyes reactive. No laila, ʻo 4,4'-diaminodiphenyl ether kahi waena me ka waiwai i hoʻohui ʻia.

1. ʻO 4'-ODA kekahi o nā mea maka koʻikoʻi no nā plastics ʻenekinia kūikawā hou e like me ka polyimide, polyetherimide, polyesterimide, polymaleimide, polyaramid a me nā resins pale wela kiʻekiʻe ʻē aʻe;
2. Hoʻohui ʻia hoʻi ka 4'-ODA. ʻO ka mea maka o 3,3',4,4'-tetraaminodiphenyl ether, ʻo ia ka monomer nui no ka hoʻomākaukau ʻana i kahi moʻo o nā mea polymer heterocyclic aromatic e kūʻē i ka wela.
3. Hoʻohana ʻia ʻo 4,4'-DPE ma ke ʻano he mea maka a me ka mea hoʻopili no ka resin epoxy pale wela kiʻekiʻe, polyurethane a me nā polymer synthetic ʻē aʻe.
4. Hoʻohana ʻia hoʻi ʻo 4,4'-DPE e pani i ka benzidine carcinogenic i ka hana ʻana i nā dyes azo, nā dyes reactive a me nā mea ʻala. I kēia manawa, me ka hoʻohana ʻana i ka diaminodiphenyl ether ma ke ʻano he mea maka, ua hoʻomohala ʻia nā dyes pololei o nā pae kala like ʻole e like me ka ʻulaʻula ʻālohilohi, ʻulaʻula ʻālohilohi, ʻulaʻula one, melemele-brown, ʻōmaʻomaʻo, hina, uliuli, ʻalani ʻālohilohi a me ka ʻeleʻele, hiki ke hoʻohana ʻia no ka silika, ka hulu hipa, ka pulupulu. ʻOi aku ka maikaʻi o ka dyeing o ka hemp a me nā lole ʻē aʻe ma mua o nā dyes benzidine ma ke ʻano o ka paʻa o ke kala a me ka wikiwiki o ka pau ʻana.
