| Chemical Properties |
Sodium dimethyldithiocarbamate is a clear yellow liquid or yellow crystalline solid |
| General Description |
Crystals or liquid. Becomes anhydrous at 266°F. |
| Air & Water Reactions |
Slowly decomposes in aqueous solution to form carbon disulfide and m or other amines. Such decompositions are accelerated by acids. |
| Reactivity Profile |
Flammable gases are generated by the combination with aldehydes, nitrides, and hydrides. Incompatible with acids, peroxides, and acid halides. |
| Health Hazard |
ACUTE/CHRONIC HAZARDS: When heated to decomposition it emits very toxic fumes. |
| Fire Hazard |
Flash point data for Sodium dimethyldithiocarbamate are not available. Sodium dimethyldithiocarbamate is probably not flammable. |
| Safety Profile |
Moderately toxic by ingestion and intraperitoneal routes. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx, SOx, and Na2O. See also CARBAMATES. |
| Potential Exposure |
The slow release of poisonous gases from hydrolysis of many thio and dithiocarbamates requires the use of respirators during handling. Used as an antimicrobial/fungicidal agent in paints, water treatment; a registered biocide for cutting oils and aqueous systems in industries such as leather tanning and paper manufacturing. Used in the rubber industry as a vulcanization accelerator for making synthetic and natural rubbers (i.e., butadiene rubber, latex). Used as a fungicide on melons (tolerance set as 25 ppm). Also used as an indirect food additive for use only as a component of adhesives. |

| Purification Methods |
Crystallise it from a small volume of H2O, or dissolve it in the minimum volume of H2O and add cold Me2CO, collect it and dry it in air. The solubility in Me2CO is 50g/400mL. The dihydrate loses H2O on heating at 115o to give the hemi-hydrate which decomposes on further heating [Kulka Can J Chem 34 1096 1956]. [Beilstein 4 IV 233.] |
| Incompatibilities |
Slowly decomposes in water, forming carbon disulfide, oxides of sulfur and nitrogen, hydrogen sulfide, ammonia, and amines, including m; this decomposition is accelerated in the presence of acids. Flammable gases are generated by the combination with aldehydes, nitrides, and hydrides. Incompatible with acids, peroxides, and acid halides. Thiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of thiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and m. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and m or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of thiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates are incompatible with carboxylic acid acids, peroxides, and acid halides. |
