as compounds of mercury, arsenic, antimony,
bismuth and the like, the efliciency of which have hitherto been greatly limited by the difliculty of producing readily soluble compounds.v In carrying out the process of my invention, I react upon an organo-metallic compound with a suitable organic compound.
which is either water soluble or has water soluble salts and which contains the thio-' hydroxyl group (SH). The initial organic metallic compound used may have the general formula (It-) M(-w) in which R is any organic group having .the metal attached to a carbon atom, a: is any replace 3 able inorganic roup of other than the sulphur family, L? is any metal which has a valence greater than 1 and which will form organo-metallic compounds stable toward water and with the metal bondedto a carbon :5 atom, and n and n are each integers greater than zero and at least one less than the valence of the metal. The initial thiohydroxyl compound used is of the general formula H-S-R,,, in which R is an or- 40 anic radical containing an acid group and having a carbon atom directly bonded to S; or a soluble salt of'the acid shown by that eneral formula. In other words, the initial t iohydroxyl compound used contalns the;
thiohydroxyl group 'SH with the sulphur atom bonded to an acid-forming organic radical which when so bondedstill has a se arate valence bond capable of combining w th a positive ion hydro'gen or a metal- 5 and which if joined to hydrogen forms an acid or if joined to sodium or potassium I formsthe corresponding salt. Thus I may use the alcohols such as ethyl mercaptan,
thioglycerine, or thioglycol, or carboxylic compounds, such as thioglycollic acid, thio lact c acid, thiomalic acid, thiosalicylic acid, etc., or their salts; or analogous sulfonic compounds; or thiophenols, such as thioresorc1ono1, thionaphthol; and like products.
A typical formula for the initial organometallic compounds is as follows: RHgw in which R is any organic radical havin the Hg attached to a carbon atom and in Vllflh :0 1s any replaceable inorganic radical or group. Hg can be replaced by any metal havlnga valence greater than one which will form organo-metallic compounds with the metal bonded to a carbon atom and which compounds are stable toward water. These metals are in general those lying lower than hydrogen in the electro-motive series.
By the general process outlined,-I may tain organo-metallic compounds, or salts thereof, of the following general formula:
rtn. M('-s RA, in which R, M, R n, and n are as above described. Some of the acids themselves are water-soluble, and all the sodium and p0- tassium salts thereof are water-soluble. The following specific examples illustrate the invention:
Example 1.
Phenyl mercury chloride, C,,I-I,,.HgCl, is
treated with potassium thioglycollate, HS'CH COOK.. The potassium thioglycollate, which is water soluble, is first dis-' mercury compound passes readily into solu-- tion, apparently as the compound having the formula C H, ,Hg-S-CH,'COOK. The following reaction takes place CJLHgCl HS-CH COOK-r To neutralize the hydrochloric acid resultbe added to the solution.
any other acid may be added. A white ing from the above reaction the requisite amount of sodium bicarbonate, NaI'ICO may To purify the product thus formed, hydrochloric acid or precipitate is formed which is I This substance melts, with decomposition, at 164 C. This may be collected on a filter, washed well with water to remove any inorganic salts, dried in a desiccator and then dissolved in the calculated amount of sodium or potassium hydroxide and 'the whole poured into 95% alcohol. The salt separates andis collected on a filter. This salt is water-soluble.
Example 2.
\ o I I To a concenti'ated water solutlon containin 0.1 mole of the sodium salt of thiosalicy ic acid, the equivalent amount of plienyl mercuric chloride is added and the whole heated for 15 minutes, when the phenyl mercuric chloride goes into solution in the form The addition of a .small amount of sodium carbonate is quite beneficial for it neutralizes the hydrochloric acid formed in the reaction.
ab 013 2 0H3 The alcoholicsolution is then evaporated to dryness in vacuo. The residue is treated with water and then a small amount of acetic acid is added. The precipitate thus obtained is washed well with water and collected on the filter and then dissolved in the concentrated solution of one equivalent of sodium hydroxide and the whole poured into a mixture of alcohol and ether. The followingsalt separates:
011.03, aEst scngcooua The compoundthus obtained is soluble in water, insoluble in alcohol-ether mixture, insoluble in benzene and other common organic solvents. Upon boilin for a long time in water the solution is iroken down. It has no melting point.
Emwmple 4.
To an alcoholic solution of phenyl arseni ous chloride an e uivalent amount of the potassium salt of t iogl collic acid is added and the whole warme for about five min- The compound thus obtained, namely may be purified by treating the water solution with an acid. A compound B-HgC|H; separates which can be collected on a filter and washed free from all impurities. The precipitate can then be dissolved in the calculated amount of a sodium hydroxide solution and the latter poured into 95% alcohol.
S-r-HI-CgH separates. This product is water soluble.
The salt has no melting point and is insoluble in ether, alcohol, and other organic solvents. When boiled for a long period of time, particularly in concentrated solution, mercuric sulfide separates. The free acid of this salt may be obtained by the addition of any strong acid.
F Emample 3;
To an alcoholic solution of p-tolyl antimony chloride the? equivalent amount of sodium or potassium salt of thioglycollic acid is added and the whole warmed for five minutes on a water bath. The following compound is produced:
