Phenylmercuric hydroxide

Diphenylmercury [587-85-9] M 354.8, m 125.5-126 . Sublimed, then crystd from nitromethane or ethanol. If phenylmercuric halides are present they can be converted to phenylmercuric hydroxide which, being much more soluble, remains in the alcohol or benzene used for crystn. Thus, crude material (lOg) is dissolved in warm ethanol (ca 150mL) and shaken with moist Ag20 (ca lOg) for 30min, then heated under reflux for 30min and filtered hot. Concentration of the filtrate by evaporation gives diphenylmercury, which is recrystd from benzene [Blair, Bryce-Smith and Pengilly J Chem Soc 3174 7959]. TOXIC.

The PhEur 2005 material is a compound consisting of equimolecular proportions of phenylmercuric hydroxide and phenylmercuric orthoborate (Ci2Hi3BHg204) or of the dehydrated form (metaborate, Ci2HuBHg203), or a mixture of the two compounds. 

Phenylmercuric borate may be prepared by heating mercuric borate with benzene or by evaporating to dryness, under vacuum, an alcoholic solution containing equimolar proportions of phenylmercuric hydroxide and boric acid. 

Note that the synonyms above are usually used to refer to phenylmercuric nitrate alone. However, confusion with nomenclature and CAS Registry Number has led to these synonyms also being applied to the PhEur 2005 and USPNF 23 material, which is a compound of phenylmercuric nitrate and phenylmercuric hydroxide. 

There are two CAS Registry Numbers associated with phenylmercuric nitrate. One refers to the mixture of phenylmercuric nitrate and phenylmercuric hydroxide (Ci2HiiHg2N04) while the other refers to phenylmercuric nitrate alone (CgH5HgN03). The PhEur 2005, and USPNF 23 use the name phenylmercuric nitrate to describe the mixture and use the CAS Registry Number [55-68-5]. 

Phenylmercuric nitrate PhEur 2005, and USPNF 23, is an equimolecular compound of phenylmercuric hydroxide and phenylmercuric nitrate it occurs as a white, crystalline powder with a slight aromatic odor. 

Phenylmercuric Nitrate, NF. Phenylmercuric nitrate is a mixture of phenylmercuric nitrate and phenylmercuric hydroxide. It occurs as a white crystalline material that is sparingly soluble in water and. slightly soluble in alcohol. It is u.sed in concentrations of 1 10,000 to 1 50,000 to preserve injectable drugs against bacterial contamination. A disadvantage to organomercurials is that their bacteriostatic efficacy is reduced in the presence of. scrum. 

A primary hydrogen deuterium kinetic isotope effect of 1.9 was found when Janout and Regen used deuterium oxide in place of water in the hydration of the adduct formed when phenylmercuric hydroxide reacts with terminal alkynes. The first step in this reaction...
