Mercuric Nitrate

CAS RN: 10045-94-0

Reactivities / Incompatibilities

Acetylene forms a sensitive acetylide when passed into aq soln of mercuric nitrate. Mercuric nitrate is violently reduced to mercury by hypophosphoric acid. Mercuric nitrate reacts with unsaturated & aromatic cmpd with violence if given time to generate enough heat.
Gas oil was stirred vigorously with the finely divided solid nitrate to complete the removal of sulfur compounds. After the mixture had congealed, preventing further stirring, a violent reaction set in, which reached incandescence, accompanied by vigorous evolution of nitrous fumes. This was attributed to the self-catalyzed nitrating action of mercury nitrate in a semi-solid environment unable to lose heat effectively. A similar occurrence was observed when crushed nitrate was just covered with cracked naphtha. ... This type of hazard was known in cracked distillates containing high proportions of unsaturated and aromatic cmpd, when allowed to stand in prolonged contact with mercury(2+) nitrate. The hazard may be avoided by using several small portions of the salt sequentially and working with 100 g portions of hydrocarbons.
Alcohol should not be mixed with mercuric nitrate, as explosive fulminate may be formed. The reaction of phosphines & mercuric nitrate gives a yellow precipitate which explodes when heated or subjected to shock. An explosion occurred during the use of mercuric nitrate for determining sulfur in ball's reaction.
Phosphine reacts with aqueous salt solution to give a complex nitrate phosphide, which when dry explodes on heating or impact.
Phosphinic ('hypophosphorus') acid violently reduces the salt to the metal.
