NH2SO3H Sulfamic acid

Plutonium metal dissolves readily in sulfamic acid (NH2SO3H) at ambient temperatures according to the reaction... [Pg.100]

Miscellaneous methods. Sulfamic acid (NH2SO3H) has been used mainly In synthesis of sulfate conjugates of steroids (94.95). However the reaction, catalysed by pyridine and performed at 80-100 C for an hour, has also been used for phenolic subtrates (.77). Pyrldlnlum sulfate and acetic anhydride has been used for synthesis of estrone sulfate (9 ). [Pg.136]

A 0.1 M sodium hydroxide solution is to be standardized by titrating primary standard sulfamic acid (NH2SO3H). What weight of sulfamic acid should be taken so that the volume of NaOH delivered from the buret is about 40 mL ... [Pg.186]

Sulfamic acid, NH2SO3H, is a stable, high-melting (200 C) crystalline solid with strongly acidic properties. It is available commercially, being prepared by reacting urea with pyrosulfuric acid. [Pg.329]

Sulfamic acid, NH2SO3H, is an ammonoaquosulfuric acid in which one of the hydroxyl groups of sulfuric acid has been replaced by the isosteric amido group. It is prepared commercially by the interaction of fuming sulfuric acid and urea. This method is not readily adaptable to laboratory preparation on a small scale. Consequently, the sulfur dioxide-hydroxylamine reaction is recom-mended.H Sulfamic acid may also be obtained by the action of sulfur dioxide upon certain compounds which yield hydroxylamine such as acetoxime. The recommended procedures are modifications of older processes and involve the use of sulfur dioxide under pressure upon aqueous solutions of hydroxylammonium salts and compounds yielding hydroxylamine. [Pg.176]
