sodium de l'acide 4-amino-2-auromercap'obenzol-1-sulfonique (voir l'exemple 2 de la description du brevet principal).
En procédant d'une façon similaire on obtient des combinai- sons analogues des métaux lourds.
Exemple 1.
On fait dissoudre 42,3 parties de 4-amino-2-auromercaptoben- zol-1-sulfonate de soude dans 200 parties. d'eau; on ajoute 13 parties de soude formaldéhydo-sulfureuse, et l'on chauffe la so-

Exemple 2.

4-amino-2-argentomereaptobenzol-l-sulfonate de soude, puis on ajoute 14 parties de soude forraaldéhydo-sulfureuse, et l'on chauffe la solution tout en l'agitant , jusqu'à l'ébullition.
Après le refroidissement on provoque la précipitation, par l'al- cool, du composé bisulfito-formaldéhyde ainsi formé.
Le sel de dinatrium de l'acide 4-iminométhylène sulfureux- acide-2-argentomercaptobenzol-l-sulfonique est une poudre d'un jaune clair,très facilement soluble dans l'eau, et sa teneur en argent est de 24 %.
Exemple 3.
On fait dissoudre dans 150 parties d'eau 29,5 parties de 4-
EMI2.3
amino-2-bismutomercaptobenzol-l-sulfonate de soude, puis on ajoute 14 parties de soude formaldéhydo- sulfureuse, et l'on chauffe jusqu'à ébullition. La solution d'un brun rougeâtre clair est, après refroidissement ,précipitée par l'alcool, et le produit de la condensation s'obtient ainsi sous forme d'une poudre d'un jaune orangé,facilement soluble dans l'eau, et ayant une teneur en bismuth de 16,5 %.

EMI1.1
"Process for obtaining organic meroapto-sulpho-alides of metals".
The dinatrium salt of 4-iminomethylene sulfurous acid
EMI1.2
aeide-2-auromercaptobenzol-1-sulfonic (see Example 3) can; as it has been observed, also obtained by making the formaldehyde sulphurous soda act on the salt of

sodium of 4-amino-2-auromercap'obenzol-1-sulfonic acid (see Example 2 of the description of the main patent).
By proceeding in a similar fashion, analogous combinations of heavy metals are obtained.
Example 1.
42.3 parts of sodium 4-amino-2-auromercaptobenzol-1-sulfonate are dissolved in 200 parts. water; 13 parts of formaldehyde-sulphurous soda are added, and the sol-

Example 2.
33.4 parts of water are dissolved in 150 parts of water
EMI2.2
Sodium 4-amino-2-argentomereaptobenzol-l-sulfonate, then 14 parts of forraaldehyde-sulfurous sodium hydroxide are added, and the solution is heated while stirring, until boiling.
After cooling, the bisulphite-formaldehyde compound thus formed is precipitated with the alcohol.
4-Iminomethylene sulfurous acid-2-argentomercaptobenzol-1-sulfonic acid dinatrium salt is a light yellow powder, very easily soluble in water, and its silver content is 24%.
Example 3.
29.5 parts of 4- are dissolved in 150 parts of water
EMI2.3
sodium amino-2-bismutomercaptobenzol-1-sulfonate, then 14 parts of formaldehyde-sulfurous sodium hydroxide are added, and the mixture is heated to boiling. The solution of a light reddish brown is, after cooling, precipitated by alcohol, and the product of condensation is thus obtained in the form of an orange-yellow powder, easily soluble in water, and having a bismuth content of 16.5%.
