99.99% kala kala Ag2O kumu kūʻai pauka me Cas 20667-12-3
wehewehe
ʻOkika kala, kumu hoʻomāka Ag2O. Kaumaha molekula 231.74. ʻEleʻele ʻeleʻele cubic crystal a pauda. Hoʻoheheʻe mālie ka mālamalama i ke kālā a me ka oxygen. Kaumaha kiko 7.143(16.6 ℃). Ma 60 ~ 80 ℃ maloʻo aneane ʻeleʻele, wela a 300 ℃ decomposition, 250 ~ 300 ℃ decomposition wikiwiki. Hiki ke hoʻoheheʻe ʻia i ka wai a me ka hopena alkaline, hiki ke hoʻoheheʻe ʻia i loko o ka ammonia, ka pāpaʻi cyanide solution, ka waikawa nitric, ka solution sodium thiosulfate, paʻakikī ke hoʻoheheʻe i ka ethanol. Hiki i ka wai ke komo i ke kalapona mai ka lewa. Ma ke alo o ka alkali, hiki i ka wai wai formaldehyde ke hoʻemi i ke kālā metala. ʻO ke kuʻi ʻana me ka mea ola kino hiki ke hoʻopau ʻia. Ma hope o kāna solution ammonia no ka manawa lōʻihi, i kekahi manawa e hoʻoheheʻe ʻia me nā kelika ʻeleʻele pahū ikaika, ʻo ia paha ke kālā nitride Ag3N a i ʻole ke kala imimide Ag2NH. I loko o ka organik synthesis, hoʻohana pinepine ʻia nā hui hydroxyl e pani i nā mea halogen, a i ʻole he oxidants, a i ʻole he kala i ka ʻoihana aniani. Hoʻomākaukau ʻia ia e ka hana o ka solution nitrate kālā me ka solution sodium hydroxide.
Palapala noi
1. ʻO nā mea uila no nā ʻeke kālā oxide
2. Hoʻohana ʻia ia e hoʻololi i ka organobromine a me ka chloride i loko o nā ʻona, e hoʻohuli i ka phenyl methyl halide i phenyl methyl ether, a e hoʻohana pū ʻia me ka iodine methane ma ke ʻano he methylation reagent.
3, No ka catalyst ili
4, Hoʻohana ʻia e hoʻomākaukau i ka mea hoʻomaʻemaʻe wai
