Hoʻolauna
ʻO Acetaldehyde, i ʻike ʻia he acetaldehyde a i ʻole ethylaldehyde, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka acetaldehyde:
ʻAno maikaʻi:
1. He wai waihoʻoluʻu ʻole me ka ʻala ʻala a me ka ʻala.
2. Hiki ke hoʻoheheʻe ʻia i ka wai, ka waiʻona a me nā mea hoʻoheheʻe etera, a hiki ke loli.
3. Loaʻa iā ia ka polarity waena a hiki ke hoʻohana ʻia e like me ka solvent maikaʻi.
E hoʻohana:
1. Hoʻohana nui ia i ka hana ʻoihana.
2. He mea koʻikoʻi ia no ka hoʻohuihui ʻana o nā pūhui ʻē aʻe.
3. Hiki ke hoʻohanaʻia e hana i nā kinikona e like me ka vinyl acetate a me ka butyl acetate.
Hanana:
Nui nā ala e hoʻomākaukau ai i ka acetaldehyde, ʻo ka mea maʻamau e hana ʻia e ka catalytic oxidation o ka ethylene. Hana ʻia ke kaʻina hana me ka hoʻohana ʻana i ka oxygen a me nā catalysts metala (e laʻa, cobalt, iridium).
ʻIke palekana:
1. He mea ʻawaʻawa ia, he mea hoʻonāukiuki i ka ʻili, nā maka, ka ʻōpū hanu a me ka ʻōnaehana digestive.
2. He wai wela hoʻi ia, hiki ke hana i ke ahi ke ʻike ʻia i ka lapalapa ahi a i ʻole ka wela wela.
3. Pono e mālama ʻia nā hana palekana kūpono i ka wā e hoʻohana ai i ka acetaldehyde, e like me ke komo ʻana i nā mīkina lima pale, nā aniani a me nā respirator, a me ka hōʻoia ʻana i ka hana ʻana i loko o kahi kaiapuni maikaʻi.
