Used in Silver Extraction:
In the field of metallurgy, TETRAISOPROPYLTHIURAM DISULFIDE serves as an extractant for silver (I) extraction from photographic fixing solutions. This application aids in the recovery and purification of silver from waste materials.
Used in Rubber Industry:
TETRAISOPROPYLTHIURAM DISULFIDE is utilized as a rubber accelerator, enhancing the rate of vulcanization and improving the overall properties of the rubber products. This application is crucial in the manufacturing of various rubber goods, including tires, hoses, and seals.
Check Digit Verification of cas no
The CAS Registry Mumber 4136-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,3 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4136-91:
(6*4)+(5*1)+(4*3)+(3*6)+(2*9)+(1*1)=78
78 % 10 = 8
So 4136-91-8 is a valid CAS Registry Number.

Reduction Potentials of Thiuram Disulfide/Dithiocarbamate Couples in Acetone/Water
Nichols, Peter J.,Grant, Michael W.
, p. 2455 - 2463 (2007/10/02)
Reduction potentials relative to the saturated calomel electrode, Eo, of a series of thiuram disulfide/dithiocarbamate couples have been measured in 30percent v/v water in acetone and at μ 0.2 mol l-1 (NaNO3) by a combination of potentiometric measurements and equilibrium constant determinations for thiolate/disulfide interchange reactions.Eo values lie in the range -250 to -340 mV which place dithiocarbamates as intermediate between thiophenolate (Eo -540 mV) and ethylxanthate (Eo -206 mV) in reducing properties.The significant effect on Eo of varying the substituents on the nitrogen in the dithiocarbamates correlates with the substituent effects on the acid dissociation constants of the parent dithiocarbamic acid and with trends in the half-wave potentials for metal-based oxidation and reduction of transition metal dithiocarbamate complexes.
