Hoʻolauna
ʻO (2E) -2-Butene-1,4-diol, ʻike ʻia hoʻi ʻo (2E) -2-Butene-1,4-diol, he mea hoʻohuihui. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
ʻO (2E) -2-Butene-1,4-diol he wai ʻeleʻele a ʻeleʻele paha me kahi ʻala ʻala kūikawā. ʻO C4H8O2 kona paona kemika a he 88.11g/mol kona kaumaha mole. He 1.057g/cm³ kona mānoanoa, kahi paila o 225-230 degere Celsius, a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka wai, ethanol a me ka etera.
E hoʻohana:
(2E)-2-Butene-1,4-diol he nui nā hoʻohana i ka ʻoihana kemika. Hiki ke hoʻohana ʻia ma ke ʻano he intermediate in organic synthesis, no ka hoʻomākaukau ʻana i nā resins synthetic, nā uhi kiʻekiʻe, nā dyes a me nā intermediates pharmaceutical a me nā mea hoʻohui ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia e like me ka solvent a me ka surfactant i ka ʻoihana.
Kaʻina hoʻomākaukau:
Hiki ke hana ʻia ka hoʻomākaukau ʻana o (2E) -2-Butene-1,4-diol e nā ʻano hana like ʻole. ʻO kahi ala maʻamau ma ka hōʻemi ʻana i ka waikawa Butenedioic. Hiki i kēia ho'ēmi ke hoʻohana i ka mea hoʻemi e like me ka hydrogen a me ka catalyst, a i ʻole ka mea hoʻohaʻahaʻa e like me ka sodium hydride a i ʻole sulfoxide.
ʻIke palekana:
ʻO (2E) -2-Butene-1,4-diol kahi hui palekana ma lalo o nā kūlana maʻamau o ka hoʻohana. Eia nō naʻe, ma ke ʻano he mea kemika, hiki ke hoʻopilikia i ke kino o ke kanaka. Hiki i ka hoʻopili ʻana me ka ʻili, nā maka a i ʻole ka inhalation o ka mahu e hoʻonāukiuki a ʻeha ka maka. No laila, i ka lawelawe ʻana a me ka hoʻohana ʻana i (2E) -2-Butene-1,4-diol, pono e lawe ʻia nā hana palekana kūpono, e like me ke kau ʻana i nā mīkina lima pale a me nā mea pale maka, a me ka hōʻoia ʻana i kahi ʻano hana maikaʻi. I ka manawa like, pono e mālama ʻia mai ke ahi a pale i ka hoʻopili ʻana me nā oxidants ikaika. E ʻimi koke i ka lāʻau lapaʻau inā hoʻopā ʻoe a ʻai paha.
