Hoʻolauna

(E)-2-heptenal he mea hoʻohuihui. ʻO kēia ka hoʻolauna pōkole i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau, a me ka ʻike palekana o ka pūhui:

 

ʻAno maikaʻi:

(E)-2-heptenal he wai waihoʻoluʻu me ka ʻala ʻala. He polarity nāwaliwali ka mea hoʻohui a hiki ke hoʻoheheʻe ʻia i ka ethanol a me nā solvents ether.

 

E hoʻohana:

(E)-2-heptonal loaʻa kekahi waiwai noi i ka ʻoihana kemika. Hoʻohana nui ʻia ia ma ke ʻano he waena i ka synthesis o nā mea ʻala a me nā pūhui ʻē aʻe.

 

Hanana:

ʻO ka hoʻomākaukau ʻana o (E) -2-heptena e loaʻa pinepine ʻia ma o ka hoʻonā ʻana o ka heptene. ʻO ke ala maʻamau, ʻo ia ka hoʻohele ʻana i ka oxygen i loko o kahi hoʻonā o ka acetic acid acyl oxidizer o ka heptene e hoʻohua ai (E)-2-heptenal a me ka acetic acid. ʻO nā kaʻina hana lapaʻau e pili ana i ka distillation, hoʻomaʻemaʻe, a me ka wehe ʻana i nā haumia.

 

ʻIke palekana:

(E)-2-heptenal he mea hoʻonāukiuki a pono e mālama ʻia no ka hoʻopili ʻana a me ka inhalation. Hiki ke hoʻonāukiuki i ka ʻili, ka maka, a me ka ʻōpū hanu no ka lōʻihi a koʻikoʻi paha. I ka hoʻohana ʻana i (E)-2-heptenal, pono e mālama ʻia nā ʻōkuhi kūpono e like me nā mīkina lima pale a me nā aniani e hōʻoia ai i ka ea maikaʻi. I ka mālama ʻana a me ka mālama ʻana i kēia pūhui, pono e mālama ʻia nā hana palekana e pili ana, ʻoiai e mālama pono i ka pale ʻana mai ka hoʻopili ʻana me nā mea hiki ke puhi ʻia i ke ahi a pahū paha.
