Nā hiʻohiʻona huahana a me nā hana:
ʻO Carbohydrazide, i ʻike ʻia ʻo 1,3-dihydrazine-2-ylidene, he pauka crystalline keʻokeʻo e hiki ke hoʻoheheʻe ʻia i ka wai.Loaʻa iā ia kahi hui kūʻokoʻa o nā waiwai i kūpono no nā noi mai ka hana ʻana i ka mālama wai a me nā lāʻau lapaʻau.
ʻO kekahi o nā hiʻohiʻona kaulana loa o ka carbohydrazide ʻo ia kona hiki ke hoʻokaʻawale i ka oxygen a pale i ka corrosion i nā ʻōnaehana wai paila.ʻO kēia waiwai ka mea i koho nui ʻia i ka ʻoihana hana mana a ma ke ʻano he scavenger oxygen i nā boilers kiʻekiʻe.Eia kekahi, ʻo ka haʻahaʻa haʻahaʻa a me ka hoʻohaʻahaʻa ʻana i ka hopena o ke kaiapuni o nā carbohydrazides e hoʻolilo iā lākou i mau mea ʻē aʻe i nā mea hoʻoheheʻe oxygen e like me ka hydrazine.
