-ʻO ka molekala
ʻAno molekala: HCONH2
Kaumaha molekula: 45.041
Waiwai: wai waihoʻoluʻu a ʻākala, ammonia iki. ʻO ka helu heheʻe 2.55 ℃, Lae hoʻolapalapa 210-212 ℃ (decomposed hapa ma 180 ℃), Wehe uila154 ℃, Kaumaha kikoʻī 1.1334 (20 ℃). ʻO Hygroscopic, hiki ke hoʻopili me ka wai a me ka ethanol, hiki ke hoʻoheheʻe iki i loko o benzene, chloroform a me ka etera.
Hoʻohana: nā mea maka o ka lāʻau lapaʻau Synthetic, nā mea ʻala, nā mea ʻulaʻula a me nā mea ʻē aʻe, e like me ka solvent no ka wili ʻana i nā fibers synthetic, ka hoʻoili ʻana i ka plastic, ka hana ʻana i ka inika casein lāʻau. Hoʻohana pū ʻia e like me ka mea hana pepa, coagulant o ka ʻaila ʻaila a me ka ʻoihana kūkulu hale, carburizing nitriding agent i ka ʻoihana foundry, mea hoʻoheheʻe holoholona a me ka solvent polar o ka synthesis organik.
Hoʻopili ʻia, ka waiho ʻana a me ka lawe ʻana: 220L pahu pahu a i ʻole pahu kila-plastic composite. Pono e pani ʻia ke poʻi e pale aku i ka leaka a pale aku i ka pili ʻana me ka wai. Mālama ʻia ma kahi maloʻo maloʻo, mamao mai ke ahi a me ka wela.
