Hoʻolauna
ʻakika pent-4-ynoic, ʻike ʻia hoʻi ʻo pent-4-ynoic acid, ka hoʻohālikelike kemika C5H6O2. ʻO kēia ka hoʻolauna ʻana i ke ʻano, hoʻohana, hana a me ka ʻike palekana o ka pent-4-ynoic acid:
ʻAno:
- pent-4-ynoic acid he wai waihoʻoluʻu me ka ʻala ʻala.
-ʻO 102.1g/mol kona nui molekala pili.
E hoʻohana:
- pent-4-ynoic acid he mea koʻikoʻi koʻikoʻi i ka synthesis kemika a hoʻohana ʻia e hoʻomākaukau i nā pūhui ʻē aʻe.
-Hiki ke hoʻohana ʻia no ka hopena carbonylation, ka hopena condensation a me ka hopena esterification i ka hopena synthesis organik.
- hiki ke hoʻohana ʻia ka pent-4-ynoic acid i ka hoʻomākaukau ʻana i nā lāʻau lapaʻau, nā mea ʻala a me nā kala.
Kaʻina hoʻomākaukau:
-ʻO ka hoʻomākaukau ʻana o ka pent-4-ynoic acid hiki ke hoʻokō ʻia e 1-chloropentyne a me ka waikawa hydrolysis. ʻO ka mua, hoʻololi ʻia ka 1-chloropentyne me ka wai e hāʻawi i ka aldehyde a i ʻole ketone pili, a laila hoʻololi ʻia ka aldehyde a i ʻole ketone i pent-4-ynoic acid ma o ka hopena oxidation.
ʻIke palekana:
- ʻO ka pent-4-ynoic acid he mea hoʻonāukiuki hiki ke hoʻoulu i ka huhū a me ka mumū i ka pilina me ka ʻili a me nā maka.
-E hoʻohana i nā mīkina lima pale, nā aniani, a me nā lole keʻena ke hoʻohana ʻana i ka waikawa pent-4-ynoic.
-Inā pili me ka ʻili a i ʻole nā maka, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.
- Hōʻalo i ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika a me nā kumu ikaika i ka wā o ka mālama ʻana a me ka hoʻohana ʻana e pale aku i nā hopena pōʻino.
E ʻoluʻolu, ma mua o ka hoʻohana ʻana i kekahi kemika, pono ʻoe e heluhelu pono i ka pepa ʻikepili palekana (MSDS) o ka kemika a hahai i nā ʻano hana kūpono a me nā kaʻina hana palekana.
