akā-3-yn-2-one (CAS # 1423-60-5) hoʻolauna
3-butyne-2-hoʻokahi. ʻO kēia ka hoʻolauna ʻana i kona ʻano, kumu, ʻano hana hana, a me ka ʻike palekana:
ʻano:
-Nani: 3-Butyn-2-one he wai kala ʻole i ka wai melemele māmā.
-ʻala: He ʻala like me ka waiʻona a me ka hua.
-Solubility: hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik e like me nā waiʻona a me nā ethers.
Ke kumu:
Hoʻohana nui ʻia ka -3-butyne-2-one ma ke kahua o ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he mea maka, catalyst, a me ka mea hoʻoheheʻe no nā hopena kemika, a hiki ke komo i loko o nā ʻano hoʻohālikelike kūlohelohe, e like me ka nucleophilic substitution reactions a me ka hui pū ʻana.
ʻano hana hana:
-ʻO kahi ala no ka hoʻomākaukau ʻana i ka 3-butyne-2-one ma o ka hopena o ka acetone me ka propargyl alcohol. ʻO ka mea mua, hoʻopili ʻia ka acetone me ka sodium hydroxide nui e loaʻa ai ka sodium acetate, a laila hana ʻia me ka propargyl alcohol i loko o kahi ʻohi oxygen e hana ai i 3-butyne-2-one.
-Aia nā ʻano hana ʻē aʻe e hana ai i ka 3-butyne-2-one, e like me ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā huahana kūlohelohe pili, me ka hoʻohana ʻana i nā ʻano synthesis kemika, etc.
ʻIke palekana:
-3-Butyn-2-one he mea hoʻonāukiuki i nā maka, ka ʻili, a me ka ʻōnaehana hanu, a pono e holoi koke ʻia me ka wai ke hoʻopili ʻia.
-E hōʻalo i ka pilina me nā mea hoʻomake ikaika, nā ʻakika ikaika, a me nā kumu ikaika e pale ai i nā hopena ʻino.
-I ka hoʻohana ʻana i ka 3-butyne-2-one, pono e hoʻohana ʻia nā mīkina lima pale kemika, nā maka aniani, a me ka pale pale e hōʻoia i nā kūlana ea.
He mau hoʻolauna kumu kēia e pili ana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau, a me ka ʻike palekana o 3-butyne-2-one. I ka hoʻohana ʻana a me ka lawelawe ʻana i kēia pūhui, e ʻoluʻolu e hahai i nā kaʻina hana palekana a e nānā i ka ʻike palekana kūpono a me ka Blue Book of Chemical Substances.
