Hoʻolauna

ʻO Isoprenol kahi pūhui kino. He wai waihoʻoluʻu me ka ʻala ʻala. ʻO kēia ka hoʻolauna ʻana i kekahi o nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana e pili ana i ka isoprenol:

 

ʻAno maikaʻi:

Hiki ke hoʻoheheʻe ʻia ʻo Isopentenol i ka wai a me kekahi mau mea hoʻoheheʻe kūlohelohe e like me nā ʻona a me nā etera.

He ʻala ʻala ikaika kona a hiki ke hoʻonāukiuki a i ʻole ke ahi ke hoʻohu ʻia ka mahu a pili pū paha me ka ʻili.

Hiki ke hoʻohui ʻia nā mea pahū i nā kiʻekiʻe o ka waiʻona prenyl.

 

E hoʻohana:

Hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā uhi, nā mea hoʻoheheʻe, a me nā kala.

 

Hanana:

Loaʻa ke ʻano hoʻomākaukau nui o ka waiʻona isoprene e ka hopena epoxidation o isoprenene, ka mea maʻamau i catalyzed me ka hydrogen peroxide a me nā catalysts acidic.

 

ʻIke palekana:

He mea hoʻonāukiuki ka waiʻona prenyl a pono e hoʻohana ʻia me nā mea pale pono a pale i ka pili ʻana me ka ʻili a me nā maka.

Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika a me nā kumu i ka wā e hoʻohana ai a mālama ai i ka isoprenol e pale aku i nā hopena pōʻino.

He wahi uila haʻahaʻa ko Isopentenol a me ka palena pahū a pono e mālama ʻia mai nā lapalapa ahi a me nā kumu hoʻāla a hoʻohana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia.
