583-15-3 Usage
Chemical Properties
White crystals.Sensitive to
light. Soluble in solutions of sodium chloride and
ammonium benzoate; slightly soluble in alcohol
and water.
Uses
Medicine (antisyphilitic).
General Description
A white crystalline odorless solid. Melting point 165°C. Sensitive to light. Highly toxic by inhalation and ingestion.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
MERCURIC BENZOATE is soluble in solutions of sodium chloride and ammonium benzoate [Hawley]. Reacts as a weak base.
Hazard
Toxic by ingestion, inhalation, and skin
absorption; strong irritant.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Check Digit Verification of cas no
The CAS Registry Mumber 583-15-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,8 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 583-15:
(5*5)+(4*8)+(3*3)+(2*1)+(1*5)=73
73 % 10 = 3
So 583-15-3 is a valid CAS Registry Number.

ORGANOMERCURY COMPOUNDS. XXVI. THERMAL DECOMPOSITION OF MERCURIC 2,6-DISUBSTITUTED BENZOATES
Deacon, G. B.,Stretton, G. N.
, p. 123 - 136 (2007/10/02)
The main thermal decomposition path for mercuric 2,6-disubstituted benzoates, (RCO2)2Hg (R=2,6-X2C6H3; X=F, Cl, Br, or Me), can be varied considerably.In boiling dimethyl sulphoxide, decarboxylation occurs giving the corresponding diarylmercurial (X=F or Cl) or RHgO2CR derivative (X=Me or Br).There is considerable competition from reaction of the mercuric salt with the solvent in the last three cases.With boiling pyridine as medium, the 2,6-difluorobenzoate yields a mixture of R2Hg and RHgO2CR derivatives, but the 2,6-dichlorobenzoate only gives (RCO2)2Hg(py)2.Thermal decomposition of the mercuric benzoates under vacuum yields the carbozylic acids and complex mercuration products, mainly based on 3-mercurated 2,6-disubstituted benzoates, with partial additional mercuration and/or decarboxylation.Pyrolysis of mercuric 2,6-dichlorobenzoate at atmospheric pressure results in both mercuration and decarboxylation, giving m-dichlorobenzene as the main volatile product and a complex mercurial with 1,3-dimercurated-2,6-dichlorobenzene repeating units and 2,6-dichlorophenyl terminal groups.
