Hoʻolauna
ʻO ka Ethyl trans-butenoate kahi pūhui mea ola. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka pūhui:
ʻAno maikaʻi:
He wai kala ʻole ʻo Ethyl trans-butenoate me kahi ʻala ʻokoʻa. ʻOi aku ka liʻiliʻi ma mua o ka wai me ka nui o 0.9 g / mL. Hiki ke hoʻoheheʻe ʻia i loko o nā ʻano mea hoʻoheheʻe kūlohelohe, e like me ka ethanol, ethers a me nā naphthenes, ma ka wela lumi.
E hoʻohana:
Loaʻa i ka Ethyl trans-butenate nā noi like ʻole i ka ʻoihana kemika. ʻO ka hoʻohana maʻamau ma ke ʻano he intermediate in organic synthesis no ka hoʻomākaukau ʻana i nā mea hoʻohui ʻē aʻe, e like me nā oxalates, nā mea hoʻoheheʻe ester a me nā polymers. Hiki ke hoʻohana ʻia e like me nā uhi, adjuvants rubber, a me nā solvents.
Hanana:
ʻO ke ʻano o ka hoʻomākaukau ʻana o ka trans-butenoate ethyl ester e loaʻa pinepine ʻia e ka hopena o ka waikawa trans-butenoic me ka ethanol. Loaʻa kēia huahana ma ka hoʻomehana ʻana i ka waika trans-butenic a me ka ethanol ma lalo o nā kūlana acidic e hana i kahi ester.
ʻIke palekana:
ʻO ka Ethyl trans-butenoate ka mea hoʻonāukiuki i ka maka a me ka ʻili a hiki ke hoʻomake i ka maka a me ka ʻili. Pono e pale ʻia ka inhalation o kāna mau mahu i ka wā e lawelawe ai i ka pūhui, a pono e hoʻokō ʻia nā hana ma kahi wahi i hoʻoluʻu maikaʻi ʻia. I ka wā e mālama ai, pono e hoʻokomo ʻia i loko o kahi pahu airtight, ma kahi mamao o ka ignition a me nā oxidizers.
