White to off-white powder. | [Reactivity Profile]
An organosulfide amide. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). | [Air & Water Reactions]

Thiocarbanilide (diphenyl thiourea) is a crystalline compound, only marginally soluble
in water. In solution, it can assume a tautomeric form, typical of thiocarbanilide.
The first tautomer has acidic characteristics. The hydrogen can easily react with cations from
the mineral surface and therefore can act as a collector. The second form (II) does not have
collecting properties. Thiocarbanilide is a very effective and selective collector for galena.
Diphenylthiocarbazide (C6H5–NH–NH)2–C=S. This collector also appears in two forms;
in the active form the hydrogen is connected to sulfur. This reagent can be both anionic
and cationic. This collector can be utilized for flotation of nickel and cobalt minerals after
treatment of the pulp with copper sulfate. | [Purification Methods]
Crystallise the thiourea from boiling EtOH by adding hot water and allowing to cool. [Beilstein 12 H 394, 12 IV 810.] |
