Ammonium sulphamate

In order to obtain a sufficient rate of cure at moulding temperatures it is usual to add about 0.2-2.0% of a hardener (accelerator). This functions by decomposing at moulding temperatures to give an acidic body that will accelerate the cure rate. A very large number of such latent acid catalysts have been described in the literature, of which some of the more prominent are ammonium sulphamate, ammonium phenoxyacetate, ethylene sulphite and trimethyl phosphate.

Ammonium sulphamate is also unstable it hydrolyses violently in an acid medium when it is hot.

Amides of Sulphur Acids. — Similarly, amido-derivatives can be obtained from sulphur trioxide. The action of ammonia on that compound yields ammonium sulphamate, H4N—O—(S02)—NH or, if less ammonia be used, sulphamie acid, HO—(S02)—NH2 they are both crystalline, soluble compounds. 

Carefully remove 2 ml of die supernatant liquid from each of the centrifuge tubes, add to the appropriate 30-ml tube, and allow to stand for 2 to 3 minutes. To each of the tubes add, dropwise, 2 ml of a 15% solution of ammonium sulphamate to remove excess nihous acid (vigorous frodiing occurs), followed by 2 ml of 6M sodium hydroxide mix for a few seconds to remove any gas bubbles, and measure the intensity of the yellow solutions at 450 nm against the plasma blank. Calculate the concentration of paracetamol in the sample by reference to a calibration curve prepared from die values for die standard solutions. Duplicate analyses of samples and standards should be carried out.

AMMONIUM SULPHAMATE (7773-06-0) A powerful oxidizer may cause fire and explosions on contact with combustibles and reducing agents. A spontaneous reaction in hot acid solutions when enclosed or on contact with hot water, potassium, sodium, sodium nitrite, metal chlorates. Corrosive to mild steel. The sulfamate will be decomposed by raising temperature to 320°F/160°C, but elevated temperature causes a highly exothermic reaction. 

Later studies were carried out at 40 °C, 60 °C and 80 °C49. The same workers have made conductiometric studies of the ternary system ammonium sulphamate (14), ammonium sulphate (22) and water50.

The sulphamic acids 61 have been prepared by an unusual route for example, reaction of 2-HO-5-(CH3)3CC6H3CHO with ammonium sulphamate gave, after reduction with sodium borohydride and treatment with HC1, the compound 61, R = R2 = R3 = H, R1 = (CH3)3C111. 

Transfer a measured quantity of the injection, or an aqueous solution of the tablets, expected to contain between 0 02 and 0 10 mg of procaine base, into a 10-ml stoppered measuring cylinder and, if necessary, dilute with water to 5 ml. Add 1 ml of N hydrochloric acid and 0 5 ml of a freshly-prepared 1 per cent aqueous solution of sodium nitrite, mix, and allow to stand for thirty seconds. Add 1 ml of a 15 per cent aqueous solution of ammonium sulphamate, shake vigorously, allow to stand for thirty seconds, add 1 ml of a freshly-prepared 1 per cent solution of the refined acid sodium salt of l-amino-8-naphthol-3,6-disulphonic acid in 20 per cent w/v aqueous sodium hydroxide, mix and dilute to 10 ml with water.
