融点 :
95°C
比重(密度) :
1.1000
貯蔵温度 :
Keep in dark place,Inert atmosphere,Room temperature
溶解性:
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

ジエチルカルバモジチオ酸ナトリウム 化学特性,用途語,生産方法

用途

主たる用途は乳化重合スチレン‐ブタジエン、アクリロニトリル‐ブタジエンゴム製造の際の重合停止剤?ラテックス用の超加硫促進剤?重金属の捕捉剤などである。

化学的特性

White Solid

使用

An inhibitor of superoxide dismutase, having both antioxidant and oxidant effects.

使用

The -log KH of the acid is 3.4 in aqueous medium. From this fact and the distribution ratio it follows that the reagent can be extracted quantitatively from acidic media (pH < 4) with organic solvents, while at pH > 8 it remains quantitatively in the aqueous phase.
Sodium diethyldithiocarbamate reacts with even more metal ions than does dithizone. However, its analytical application is seriously limited by its considerably lower stability in acidic aqueous media. According to the examinations of Bode,the reagent undergoes considerable decomposition within 5 minutes at pH 5. The analytical application of the reagent is therefore restricted to a very narrow pH range. There is no chance with this reagent to enhance the analytical selectivity of extractions by making use of the difference between the stabilities of its complexes with various metal ions and to choose the pH of the reaction mixture accordingly. Notwithstanding, some authors suggest extraction procedures from acidic media, for instance in the cases of such stable complexes as those of copper( II), nickel(II) and bismuth(III). However, in these procedures extraction must be done immediately after acidification of the solution, and even then the error caused by decomposition of the reagent must be taken into account. The analytical selectivity of the complexation reactions of diethyldithiocarbamate can be enhanced by using various auxiliary complexing and masking agents. EDTA is particularly useful for this purpose, but there are also other complexing agents, such as cyanide or citrate.
The reagent does not absorb in the visible region (>400 nm). On the other hand, its metal complexes are generally coloured, which makes possible the application of the reagent for spectrophotometric measurements. For instance, its cobalt complex is green (absorption maximum at 650 nm), the copper complex brown (absorption maximum at 440 nm), the iron(III) complex red (515 nm), etc. It can be seen that diethyldithiocarbamate compares favourably with dithizone and oxine, as one of the most useful extracting and spectrophotometric agents in analytical chemistry. In the following some analytical procedures using diethyldithiocarbamate are described.Besides being well proved in practice, the procedures presented may also serve as illustrations of how to develop other solvent extraction analytical procedures.
Diethyldithiocarbamate has also proved suitable for the enrichment and isolation of traces of metals. For instance, the metal content of brine or the washings obtained in the purification of contaminated air can be extracted with a solution of diethyldithiocarbamate in ethyl propionate. The ethyl propionate solution can be used directly for atomic absorption spectroscopic measurement. The sensitivity of the measurement is much higher in this medium than in water.

一般的な説明

Odorless white or slightly brown or slightly pink crystals.

空気と水の反応

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.

反応プロフィール

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 .

火災危険

Flash point data for Sodium diethyldithiocarbamate are not available; however, Sodium diethyldithiocarbamate is probably combustible.

安全性プロファイル

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
