Hoʻohana nui ʻia no ka hana ʻana i nā nitro compound, azo dyes, mordants no ka pena ʻana i ka lole, nā ʻāpana hoʻōloi, nā ʻenela hoʻomehana wela hao a me ka ʻoihana lāʻau.
Hoʻohana nui ʻo Downstream o ka lāʻau, nā kala, nā preservatives, antifreeze, ka mālama ʻana i ka metala (ka pale ʻana i ka popo), nā waena waena lāʻau, nā pesticide intermediates, interyeates dye, antifreeze, nitromethane, ethylene glycol.

Hoʻohana pinepine ʻia ka sodium nitrite ma ke ʻano he stabilizer a hoʻohui i ka ʻoihana meaʻai, a hoʻohana pū ʻia ka sodium nitrite ma ke ʻano he keʻokeʻo a me ka waihoʻoluʻu. Hiki ke hoʻohana ʻia e hana i nā kala maʻamau, nā waika ʻakika, nā kala pololei, nā kala sulfur, diazo a me nā pena azo. ʻO nā hoʻohana ʻē aʻe no ka sodium nitrite pū me ka hana o nā lāʻau make, nā pesticides organic, ka paʻi ʻana ma ka hao hao a me ke kila, e like me nā mea hoʻohiamoe polymer, antifreeze, lubricants, ka hana kāpili, pulp a me ka pepa, nā mea hoʻomaʻemaʻe ʻenehana a me nā home, a hana i nā mea maka no ka caffeine a me ka saccharin.

ʻO Sodium nitrite (NaNO₂) kahi paʻakai paʻakai i hoʻokumu ʻia e ka hui pū ʻana o ka ionite nitrite a me ka sodium ion. Maʻalahi ka sodium nitrite i ka hale inu a hoʻoheheʻe ʻia i ka wai a me ka amonia wai. He alkaline kāna wai aqueous a ʻo kona pH e pili ana iā 9. He hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻeola e like me ka etanol, ka methanol a me ka ether. Loaʻa i ka sodium nitrite kahi ʻono paʻakai a hoʻohana ʻia e hana i ka paʻakai pākaukau. E hana ka sodium nitrite me ka oxygen e hana i ka sodium nitrate ke hōʻike ʻia i ka ea. Inā wela ma luna o 320 ° C, e hoʻopau ia e hana i ka oxygen, nitrogen oxide a me ka sodium oxide. Maʻalahi ka hoʻopili ʻana me nā mea ʻokanika e puhi a pahū. Ma muli o ka ʻono paʻakai a me ke kumu kūʻai haʻahaʻa, hoʻohana pinepine ʻia ia ma ke ʻano he pani kūpono ʻole no ka paʻakai pākaukau ke hana ʻana i ka meaʻai kū kānāwai ʻole. No ka mea ʻona ka sodium nitrite, ʻo ka meaʻai i loaʻa ka paʻakai ʻoihana e weliweli loa i nā kānaka a me ka carcinogenic.

keʻokeʻo a i ʻole mau aniani melemele, kikoʻī kikoʻī 2.168 (ma 20 ° C), maʻalahi hiki ke hoʻoheheʻe ʻia i ka wai, amonia wai, hoʻōla liʻiliʻi ʻia i ka methanol, ethanol, ethyl ether, a me ka hygroscopic nui loa.

Kumu a me ka hāʻawe

Hoʻohana nui ʻia no ka hana ʻana i nā nitro compound, azo dyes, mordants no ka pena ʻana i ka lole, nā ʻāpana hoʻōloi, nā ʻenela hoʻomehana wela hao a me ka ʻoihana lāʻau.
