Hoʻolauna
4-Pentyny-1-ol, i ʻike ʻia hoʻi he ʻona hexynyl. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 4-pentynyn-1-ol:
ʻAno maikaʻi:
ʻO 4-Pentoyn-1-ol he wai kala ʻole a melemele me kahi ʻala ʻokoʻa. He pūhui paʻa ʻole ia e hoʻopololei a hoʻololi paha iā ia iho.
E hoʻohana:
Loaʻa iā 4-Pentyne-1-ol nā waiwai o kahi alkyne a hiki ke hoʻohana ʻia i ka synthesis o nā mea hoʻohuihui ʻē aʻe. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he waena i ka synthesis organik a hiki ke hoʻohana ʻia e hoʻomākaukau i nā ethers, esters, aldehydes a me nā mea hoʻohui ʻē aʻe.
Hanana:
Nui nā ala e hoʻomākaukau ai i ka 4-pentyn-1-ol. ʻO ke ala maʻamau ka hana ʻana i ka 1,2-dibromoethane me ka sodium ethanol e hana i ka pentynylethanol, a laila hoʻomākaukau i ka 4-pentyn-1-ol ma o ka hydrogenation reaction.
ʻIke palekana:
ʻO 4-Pentoyn-1-ol ʻaʻole paʻa a paʻa i ka pane ʻana iā ia iho, a pono e mālama pono ʻia i ka wā e lawelawe ai. He mea hiki ke puhi a hiki i nā hui pahū ke ʻike ʻia i nā lapalapa ahi a i ʻole nā wela kiʻekiʻe. ʻO ka pili ʻana me ka ʻili a i ʻole nā maka paha e hoʻoulu ʻia ai ka ʻeha a me ka huhū, a pono e lawe ʻia nā hana pale pilikino e like me nā mīkina lima a me nā maka aniani i ka wā e hana ai pēlā. E hana ma kahi ea maikaʻi a mamao i ke ahi. Ina inhaled a inested, e imi koke i ke kauka. E ʻoluʻolu e hahai i nā kaʻina hana palekana no ka hoʻohana pono ʻana.
