Nitrite, potassium reaction with amines

AMMONIUM SULPHATE (7783-20-2) H8N2O4S Noncombustible solid. Aqueous solution is a strong acid. Violent reaction with fused potassium chlorate potassium nitrite. Reacts with caustics, forming ammonia. Hot material reacts with nitrates, nitrites, chlorates. Incompatible with strong oxidizers sulfuric acid aliphatic amines alkanolamines, amides, organic anhydrides isocyanates, vinyl acetate aUcylene oxides epichlorohydrin. Mixture with sodium hypochlorite forms nitrogen trichloride, an unstable explosive material. Attacks metals in the presence of moisture. 

PHENYLIC ACID (108-95-2) C HjOH Combustible solid, smelt (molten), or liquid [explosion limits in air (% by volume when heated) 3 to 10 flash point 174°F/79°C autoignition temp 1319°F/715°C Fire Rating 2]. Violent reaction with butadiene, strong oxidizers. Reacts, possibly violently, with strong acids caustics, aliphatic amines amides, oxidizers, calcium hypochlorite formaldehyde, lead diacetate menthol, P-naphthol, peroxydisulfuric acid peroxymonosulfuric acid potassium hydroxide sodium nitrite 1,2,3-trihydroxybenzene. Liquid attacks some plastics, rubber and coatings hot liquid attacks aluminum, magnesium, lead, and zinc. On small fires, use CO2 or dry chemical extinguishers. 

POTASSIUM NITRITE (7758-09-0) Noncombustible, but many chemical reactions can cause fire and explosions. A powerful oxidizer. Reacts with acids, acid fumes, producing nitrous fumes. Violent reaction with many substances, including reducing agents, alcohols, ammonium salts, amines, boron, combustible materials, ethers, finely divided metals, organic substances, nitric acid, potassium, sulfuric acid. Incompatible with ammonium sulfate, barium sulfide, potassium amide. Decomposes or may explode in elevated temperatures. 

The experimental conditions necessary for the preparation of a solution of a diazonium salt, diazotisation of a primary amine, are as follows. The amine is dissolved in a suitable volume of water containing 2 5-3 equivalents of hydrochloric acid (or of sulphuric acid) by the application of heat if necessary, and the solution is cooled in ice when the amine hydrochloride (or sulphate) usually crystallises. The temperature is maintained at 0-5°, an aqueous solution of sodium nitrite is added portion-wise until, after allowing 3-4 minutes for reaction, the solution gives an immediate positive test for excess of nitrous acid with an external indicator—moist potassium iodide - starch paper f ...
