Hoʻolauna

ʻO 1-pentanol, i ʻike ʻia ʻo n-pentanol, he wai kala ʻole. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 1-pentanol:

 

ʻAno maikaʻi:

- Ke ʻano: wai kala ʻole me kahi ʻala kūikawā.

- Hiki ke hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe ʻia ka 1-pentanol i ka wai, nā eter a me nā mea hoʻonā waiʻona.

 

E hoʻohana:

- Hoʻohana nui ʻia ka waiʻona 1-Penyl i ka hoʻomākaukau ʻana i nā detergents, detergents a me nā solvents. He mea koʻikoʻi ia i ka ʻoihana maka a hoʻohana nui ʻia i ka hana ʻana i nā surfactants.

- Hiki ke hoʻohana ʻia e like me ka lubricant a me ka solvent i nā pena a me nā pena.

 

Hanana:

- 1-Hoʻomākaukau pinepine ʻia ka waiʻona Penyl e ka oxidation o n-pentane. Loaʻa ka N-pentane i kahi hopena hoʻonaʻauao e hana i ka valeraldehyde. A laila, loaʻa ka valeraldehyde i ka hopena hoʻemi e loaʻa ai ka 1-pentanol.

 

ʻIke palekana:

- ʻO ka waiʻona 1-Penyl he wai lapalapa, a pono e uku ʻia i ka hōʻiliʻili ʻana o ka uila a me ka uila i ka wā e hoʻohana ai.

- Hiki i ka pili me ka ʻili ke hoʻonāukiuki, a pono ke pale ʻia ka pili lōʻihi me ka ʻili. Pono e ʻaʻahu ʻia nā lako pale pilikino i ka wā e pono ai.

- ʻO ka inhalation a i ʻole ka ʻai ʻana i ka 1-pentanol hiki ke hōʻeha i ka ʻūhā, nausea, a me ka pilikia o ka hanu ʻana.
