| solubility | about 35 % in water, less soluble in organic solvents. However, the free acid, diethyldithiocarbamic acid, is readily soluble in organic solvents and less soluble in water. Thus, on acidification of an aqueous solution of a diethyldithiocarbamate, the free acid can be extracted with chloroform or carbon tetrachloride. The distribution ratio is 2,360 for chloroform and 343 for carbon tetrachloride. |

Sodium diethyldithiocarbamate Chemical Properties,Uses,Production
Chemical Properties
Sodium diethyldithiocarbamate is a white or colorless crystalline powder, easily soluble in water and alkaline, soluble in alcohol, rapidly decomposed in acidic aqueous solution to separate out carbon disulfide and make the solution cloudy. In ammonia medium, it generates precipitate or brown colloidal solution with copper ion. Copper reagent is applied in the color development reaction of copper, used as precipitant and solvent extractant of soft metal ions, also used as photometric reagent for the determination of bismuth, copper, nickel and other metals.
Uses
Sodium diethyldithiocarbamate is an organic molecular entity. It is an inhibitor of superoxide dismutase, having both antioxidant and oxidant effects.
Preparation
This salt is obtained by treating carbon disulfide with diethylamine in the presence of sodium hydroxide:
CS2+ HN(C2H5)2+ NaOH → NaS2CN(C2H5)2+ H2O
General Description
Odorless white or slightly brown or slightly pink crystals.
Air & Water Reactions
Water soluble. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids.
Reactivity Profile
Sodium diethyldithiocarbamate is not compatible with strong oxidizing agents. Aqueous solutions slowly decompose to form carbon disulfide and an amine. Such decompositions are accelerated by acids. Addition of acid to the aqueous solution produces a white turbidity .
Fire Hazard
Flash point data for Sodium diethyldithiocarbamate are not available; however, Sodium diethyldithiocarbamate is probably combustible.
Safety Profile
Moderately toxic by ingestion, intraperitoneal, and subcutaneous routes. Experimental reproductive effects. Questionable carcinogen with experimental neoplastigenic and teratogenic data. Human mutation data reported. When heated to decomposition it emits very toxic fumes of NOx, SOx, and Na2O. Used as a pesticide. See also CARBAMATES
