Hōʻike huahana:
(1) ʻO ka sodium nitrite maʻamau: nā kristal keʻokeʻo maikaʻi, a i ʻole melemele māmā.
(2) ʻO ka pauka maloʻo sodium nitrite: keʻokeʻo keʻokeʻo, ʻaʻohe lumps, wehe. Kaumaha kikoʻī 2.168, ʻala ʻole, paʻakai liʻiliʻi, hiki ke hoʻoheheʻe ʻia, hiki ke hoʻoheheʻe ʻia i ka wai, ka helu heheʻe o 271°C, ka wela decomposition o 320°C, oxidative a me reductive. Hoʻoheheʻe mālie ʻia i loko o ka sodium nitrate i ka lewa, maʻalahi e hana i nā pūhui nitrogen me nā pūʻulu amino ma ka wela haʻahaʻa.
(3) ʻO ka Sodium Nitrite ka meaʻai he keʻokeʻo a i ʻole ka melemele rhombohedral kristal a pauka paha, molecular formula NaNo2, melting point 271 ° C, paʻakai iki, maʻalahi i ka deliquesce, hiki ke hoʻoheheʻe ʻia i ka wai, ʻo ka wai wai he alkaline, i ka lewa hiki ke mālie. oxidized i ka sodium nitrate.
Noi:
(1) Hoʻohana nui ʻia e like me nā mea maka no ka hana ʻana i nā pūhui nitro, nā dyes azo, a me nā mea ʻē aʻe.
(2) Hoʻohana nui ʻia ʻo Sodium Nitrite meaʻai ma ke ʻano he mea kala i ka hana ʻai. Hoʻohui ʻia ia i ka meaʻai e like me nā lula, akā ʻo ka ʻai nui ʻana e hōʻeha i ke kino o ke kanaka.
Pākē: 25 kgs / ʻeke a i ʻole e like me kāu noi.
E mālama: E kūʻai ma kahi wahi maloʻo.
Mana Hoʻokō: International Standard.
