OLELO HOOLAHA
ʻO Cis-2-penten-1-ol (cis-2-penten-1-ol) kahi mea hoʻohuihui.

Nā waiwai:
He wai kala ʻole ʻo Cis-2-penten-1-ol me kahi ʻala hua. He 0.81 g/mL kona mānoanoa. hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik i ka lumi wela, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He mole mole chiral kēia pūhui a aia i loko o nā isomers optical, ʻo ia hoʻi, loaʻa iā ia nā conformations cis a me ka trans.

Hoʻohana:
Hoʻohana pinepine ʻia ʻo Cis-2-penten-1-ol ma ke ʻano he solvent organik i ka ʻoihana kemika.

Ke ʻano o ka hoʻomākaukau ʻana:
Nui nā ala e hoʻomākaukau ai i ka cis-2-penten-1-ol, loaʻa ke ʻano maʻamau e ka hoʻohui ʻana ma waena o ka ethylene a me ka methanol i mua o kahi catalyst acidic.

ʻIke palekana:
He mea hoʻonāukiuki ʻo Cis-2-penten-1-ol a hiki ke hoʻoulu ʻia ka ʻili a me nā maka. He mea nui ka palekana i ka hoʻohana ʻana a pale i ka pili pono ʻana me ka ʻili a me nā maka. Inā pili, holoi koke me ka wai a ʻimi i ka lāʻau lapaʻau. Pono e mālama ʻia ma kahi ʻoluʻolu, maloʻo, maikaʻi-ventilated ma kahi mamao loa mai nā kumu hoʻāla a me nā mea hoʻoheheʻe.
