Hoʻolauna pōkole
ʻIke ʻia ʻo 2-Methyl-2-pentenal he prenal a hexenal paha. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka pūhui:
ʻAno maikaʻi:
ʻO 2-Methyl-2-pentenal kahi wai kala ʻole me kahi ʻala ʻokoʻa. He wai ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik he nui. Ma ka lumi wela, he haʻahaʻa kona kaomi mahu.
E hoʻohana:
Loaʻa i ka 2-Methyl-2-pentenal kahi ākea o nā noi ʻoihana. Hiki ke hoʻohana ʻia e like me ke kōkua ʻana i ka lāʻau lapaʻau, rubber antioxidant, resin solvent, etc.
Hanana:
Loaʻa pinepine ʻia ka hoʻomākaukau ʻana o 2-methyl-2-pentenal e ka hopena o isoprene a me formaldehyde. ʻO nā ʻanuʻu kikoʻī e like me kēia: ma ke alo o kahi catalyst kūpono, hoʻohui ʻia ka isoprene a me ka formaldehyde i ka reactor ma kahi ʻāpana a mālama ʻia i kahi mahana kūpono a me ke kaomi. Ma hope o ka hoʻokō ʻia ʻana o ka hopena no kekahi manawa, hiki ke loaʻa ka 2-methyl-2-pentenal i hoʻomaʻemaʻe ʻia ma o nā kaʻina hana e like me ka unuhi ʻana, ka holoi wai, a me ka distillation.
ʻIke palekana:
ʻO ka 2-Methyl-2-pentenal kahi lāʻau ʻawaʻawa hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu ke ʻike ʻia. E hoʻohana i nā mea pale kūpono i ka wā e hana ai a pale aku i ka pilina pololei e like me ka hiki. He wai wela hoʻi ia a pono e pale ʻia mai ka hoʻopili ʻana me nā wela kiʻekiʻe, nā lapalapa hāmama a me nā mea hoʻoheheʻe. I ka wā o ka leaka ulia, pono e lawe koke ʻia nā hana kūpono e hoʻomaʻemaʻe a hoʻopau.
