    An alternative way of producing potassium nitrate without a by-product of ammonia is to combine ammonium nitrate, found in instant ice packs, [30] and potassium chloride, easily obtained as a sodium-free salt substitute. NH 4 NO 3 + KCl → NH 4 Cl + KNO 3. Potassium nitrate can also be produced by neutralizing nitric acid with potassium ...

    In a laboratory procedure, the oxidation of naphthalene with alkaline potassium permanganate is given, which, however, yields only a yield of 39% 2-carboxybenzaldehyde. [9] Also the oxidation of naphthalene with ozone to 2-formylbenzoic acid offers no significant advantages. [10] Synthese von 2-Carboxybenzaldehyd aus Naphthalin
