The first published preparation was reported by V. Voorhees and Roger Adams. [2] The procedure involves first preparing a platinum nitrate which is then heated to expel nitrogen oxides. [3] H 2 PtCl 6 + 6 NaNO 3 → Pt(NO 3) 4 + 6 NaCl (aq) + 2 HNO 3 Pt(NO 3) 4 → PtO 2 + 4 NO 2 + O 2. The resulting brown cake is washed with water to free it ...
Ammonium hexachloroplatinate, also known as ammonium chloroplatinate, is the inorganic compound with the formula (NH 4) 2 [PtCl 6]. It is a rare example of a soluble platinum(IV) salt that is not hygroscopic. It forms intensely yellow solutions in water. In the presence of 1M NH 4 Cl, its solubility is only 0.0028 g/100 mL.
Ammonium chromate – [NH 4] 2 CrO 4 [38] Ammonium cerium(IV) nitrate – [NH 4] 2 [Ce(NO 3) 6] Ammonium cerium(IV) sulfate – [NH 4] 4 [Ce(SO 4) 4] Ammonium chloride – [NH 4]Cl [39] Ammonium chlorate – [NH 4]ClO 3 [40] Ammonium cyanide – [NH 4]CN [41] Ammonium dichromate – [NH 4] 2 Cr 2 O 7 [42] Ammonium dihydrogen phosphate – [NH 4 ...
When heated to 150–180 °C, it decomposes with autooxidation to plutonium (VI) with the formation of plutonyl nitrate (PuO 2 (NO 3) 2).Upon evaporation of concentrated nitric acid solutions of plutonium nitrate and alkali metal nitrates, double nitrates of the composition M 2 [Pu(NO 3) 6] are formed, where M = Cs +, Rb +, K +, Tl +, NH 4 +, analogous to ceric ammonium nitrate.

The reduction of nitroaromatics is conducted on an industrial scale. [1] Many methods exist, such as: Catalytic hydrogenation using: Raney nickel [2] or palladium-on-carbon, [3] [4] [5] platinum(IV) oxide, or Urushibara nickel. [6] Iron in acidic media. [7] [8] [9] Sodium hydrosulfite [10] Sodium sulfide (or hydrogen sulfide and base ...
Ceric ammonium nitrate (CAN) is the inorganic compound with the formula (NH 4) 2 [Ce(NO 3) 6]. This orange-red, water-soluble cerium salt is a specialised oxidizing agent in organic synthesis and a standard oxidant in quantitative analysis .
