105-77-1 Usage

General Description

Dibutyl xanthogen disulfide is a chemical compound commonly used as a flotation reagent in the mining industry. It is a yellow crystalline solid with a molecular formula of C8H14S4O2 and a molecular weight of 290.43 g/mol. Dibutyl xanthogen disulfide is known for its ability to selectively bind to mineral surfaces, making it useful in separating valuable minerals from gangue in the process of ore flotation. It is also used as a vulcanization accelerator in the production of rubber and as a stabilizer in the production of PVC. Additionally, it can be used as a chemical intermediate in the synthesis of other organic compounds. While it has practical applications, dibutyl xanthogen disulfide should be handled with caution due to its potential to cause skin and eye irritation, as well as respiratory issues if inhaled.

Check Digit Verification of cas no

The CAS Registry Mumber 105-77-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 105-77:
(5*1)+(4*0)+(3*5)+(2*7)+(1*7)=41
41 % 10 = 1
So 105-77-1 is a valid CAS Registry Number.

A comparative study of the structure of copper and lead xanthates

Vorobyev,Saikova,Erenburg,Trubina,Ivanov, Yu. N.,Maksimov,Mikhlin, Yu. L.

, p. 1144 - 1151 (2017)

XPS, PbL3 and CuK EXAFS, solid state NMR, and EPR techniques are used to study insoluble products formed in the interaction of aqueous solutions of lead(II) nitrate and copper (II) sulfate with potassium nbutylxanthate (KX). The XPS spectra of lead xanthates with the composition PbX2 are similar to those of KX, and interatomic distances of 0.279 nm suggest a nearly ionic character of Pb–S bonds. In copper xanthate precipitating together with dixanthogen (approximately 15 wt.%), the Cu(I)–S bond length is smaller (0.229 nm), and copper coordination number of 2.9 in a composite with dixanthogen increases to 3.3 after its removal by washing with acetone. The XPS spectra indicate the covalent character of the bond and non-equivalence of xanthate radicals. Solid state 1H and 13C NMR spectra as well as the actual absence of metal lines under the measurement conditions demonstrate strong disordering of the structure of xanthates, which is stronger for PbX2 and weakest in CuX after the removal of dixanthogen. EPR reveals sulfur-containing radicals and Cu2+ in CuX, however, their amounts are insignificant and decrease after the washing with acetone. The results of the work are significant for the understanding of the reactivity of xanthates, in particular, under the conditions of flotation of base metal ores.
