Millon

Mercuric nitrite reaction (Millon s reaction). Dissolve a very small crystal of tyrosine in i ml. of water, add 1-2 drops of mercuric nitrate solution, and I drop of dil. HjSO, and then boil. Cool, add i drop of sodium nitrite solution and warm again a red coloration is obtained.

Yellow mercuric oxide may be obtained by precipitation from solutions of practically any water-soluble mercuric salt through the addition of alkah. The most economical are mercuric chloride or nitrate. Although yellow HgO has some medicinal value in ointments and other such preparations, the primary use is as a raw material for other mercury compounds, eg, Millon s ha.se[12529-66-7], Hg2NOH, which is formed by the reaction of aqueous ammonia and yellow mercuric oxide.

Chondrofoline, CgjHgjOjNj, 2H2O, crystallises from methyl alcohol in triangular plates, m.p. about 135°, [ajffg — 280-6° (dry base N/10. HCl). It is a phenolic base, contains three methoxyl groups, does not give a Millon reaction, but in methyl alcoholic solution gives a faint, pink-purple colour with ferric chloride. The nitrate forms needles m.p. 225° (dec.). 

The latter is a microcrystalline powder, m.p. 265° (efferv.), [a] + 210° (N/10 HCl), gives a Millon reaction and like all the phenolic alkaloids of this group is readily oxidised by nitric acid. 

The quaternary fraction of pot curare, after the removal of some neoprotocuridine, was separated into a portion salted out by sodium bicarbonate, and a portion not so precipitated. The latter was fractionated on a plan described in the original, the most active product obtained being an amorphous iodide with a paralysing dose of 1- 5 mg. per kilo frog. This iodide was phenolic, gave the Millon reaction, but no strychnine-like reaction with bichromate and sulphuric acid. No crystalline product could be isolated, but on complete methylation certain of the fractions yielded crystalline methiodides as follows —...

The anhydride of Millon s base explodes if touched or heated to 130°C. 

A mercury manometer used with ammonia became blocked by deposition of a grey-brown solid, which exploded dining attempts to remove it mechanically or on heating. The solid appeared to be a dehydration product of Millon s base and was freely soluble in sodium thiosulfate solution. This method of cleaning is probably safer than others, but the use of mercury manometers with ammonia should be avoided as intrinsically unsafe [1,2]. Although pure dry ammonia and mercury do not react even under pressure at 340 kbar and 200° C, the presence of traces of water leads to the formation of an explosive compound, which may explode during depressurisation of the system [3], Explosions in mercury-ammonia systems had been reported previously [4,5],... 

The tryptophane is precipitated by adding a solution of 200 g. of mercuric sulfate (Note 5) in a mixture of i860 cc. of water and 140 cc. of concentrated (95 per cent) sulfuric acid. After standing for twenty-four to forty-eight hours, the clear liquid is siphoned out and the yellow precipitate is filtered off and washed (Note 6) with a solution of 100 cc. of concentrated sulfuric acid in 1900 cc. of distilled water containing 20 g. mercuric sulfate, until the filtrate is colorless and Millon s test is atypical (Note 7) about 1500 cc. is necessary. The precipitate is washed with three successive 500-cc. portions of distilled water to remove most of the sulfuric acid.
