The ceric ammonium nitrate test
網頁In this colorimetric method, use for drinking water, wastewater and seawater, nitrate is reduced to nitrite with hydrazine sulfate. The diazonium reagents then react with the nitrite to produce a red color. The intensity of the color is proportional to the original amount of nitrate and nitrite present in the sample. 網頁Question 1 Status: Not yet answered Points possible: 1.00 The ceric ammonium nitrate (CAN) test shows the presence of Choose...

網頁2015年4月23日 · Ceric ammonium nitrate (CAN) is a single-electron-transfer reagent with unparalleled utility in organic synthesis, and has emerged as a vital feedstock in diverse chemical industries. Most applications use CAN in solution where it is assigned a monomeric [Ce IV (NO 3 ) 6 ] 2− structure; an assumption traced to half-century old studies. Ceric ammonium nitrate (CAN) is the inorganic compound with the formula (NH4)2[Ce(NO3)6]. This orange-red, water-soluble cerium salt is a specialised oxidizing agent in organic synthesis and a standard oxidant in quantitative analysis. 查看更多內容 The anion [Ce(NO3)6] is generated by dissolving Ce2O3 in hot and concentrated nitric acid (HNO3). The salt consists of the hexanitratocerate(IV) anion [Ce(NO3)6] and a pair of 查看更多內容 CAN is also a component of chrome etchant, a material that is used in the production of photomasks and liquid crystal displays. 查看更多內容 In organic synthesis, CAN is useful as an oxidant for many functional groups (alcohols, phenols, and ethers) as well as C–H bonds, especially those that are benzylic. Alkenes undergo dinitroxylation, although the outcome is solvent-dependent. 查看更多內容 • Oxidizing Agents: Cerium Ammonium Nitrate 查看更多內容
