Hoʻolauna

ʻO ka Trans-2,4-heptadienal kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻO ka Trans-2,4-heptadienal he wai melemele māmā me ka ʻala ʻala. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka etera a hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

Hoʻohana: Hiki ke hoʻohana ʻia e like me ka solvent a me ka waena ma nā hale hana kemika.

 

Hanana:

Hoʻomākaukau pinepine ʻia ʻo Trans-2,4-heptadienal e ka hoʻokahe ʻana o ka waikawa heptenic. Heptenic acid ua oxidized mua i ka heptadienoic acid, a laila e hana i ka hopena decarboxylation e loaʻa ai ka trans-trans-2,4-heptadienal.

 

ʻIke palekana:

ʻO ka Trans-2,4-heptadienal he wai lapalapa a pono e mālama ʻia mai ke ahi a me nā wela kiʻekiʻe. Pono nā hana palekana, e like me ke komo ʻana i nā maka pale, nā mīkina lima a me nā lole pale, i ka wā o ka hana. E hōʻalo i ka hoʻohu ʻana i kona mau mahu a e hōʻoia i ka hoʻoheheʻe maikaʻi ʻia o ka wahi hana. Inā pili ia me ka ʻili, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau. Inā ale ʻia, e nīnau koke i ke kauka.
