Tertiary dodecyl mercaptan (TDM) is commonly used as a chain transfer agent in the manufacturing process of styrene/butadiene latex for use in carpet and paper industries. A gas chromatographic technique has been successfully developed for the measurement of TDM based on its sulfur content for material identification, trend analysis, or for the monitoring of un-reacted residual material in final products. The method employs low thermal mass gas chromatography (LTM-GC) and a dual-plasma sulfur chemiluminescence detector (DP-SCD) to attain a high degree of sensitivity and selectivity. Using the technique described, a detection limit in the range of 0.5 ppm (v/v) TDM and less than 1 min analysis time can be achieved. Response is linear over four orders of magnitude with high degree of repeatability of less than 5% RSD. In the process of manufacturing latex such as styrene-butadiene, a chain transfer agent is required. The chain transfer agent assists in the polymerization to make products of the desired molecular distribution. Previously, chlorinatedcompounds such as carbon tetrachloride and chloroform have been used for this application, but because of their toxicity and negative environmental effects, it is no longer a practice to employ said compounds for the manufacturing of latex used for the carpet and paper industries. Instead, use of tertiary dodecyl mercaptan (TDM) is preferred for the applications described. As a result of the world demand for latex and the magnitude of the associated industries, TDM has become a chemical of industrial significance.
Highlights
-TDM is an effective collector for sphalerite with less CuSO4 and without frother.
-TDM chemisorbs on the minerals surface.
-Adsorption modes of TDM on mineral surfaces are obtained by first-principle study.
-Absorption energies of TDM on ZnS (110) and FeS2 (100) are ⿿394.78, ⿿219.33 kJ/mol.
-Reactions happen between S 3p orbital of TDM and 3d of Zn/Fe orbital of minerals.
In the flotation of sphalerite, the concomitant flotation of sulfidic (pyrite) and nonsulfidic gangue (silica) minerals significantly reduces the grade of the float concentrate. Laboratory scale experiments have been conducted to investigate the effect of tert dodecyl mercaptan (TDM) as a collector on the flotation of sphalerite. The addition of only 160 g/t copper sulfate, which is ⿼30% of that which is being used currently in the xanthate reagent scheme, improves the grade and the recovery. The selectivity for sphalerite, with respect to pyrite, has been improved significantly when copper sulfate is added with lime as the depressant, and the results could be achieved at pH 9⿿10.5.Based on the results obtained, the interaction of tert dodecyl mercaptan with sphalerite has been investigated by adsorption measurement, fourier transform infrared (FTIR) and density functional theory (DFT). It is showed that, TDM adsorbed on sphalerite surface chemically with some characteristic peaks appeared and migrated on sphalerite surface in FTIR tests. Compared with butyl xanthate, a stronger interaction between TDM and sphalerite is determined by analyses of frontier orbital energy calculation. It is also indicated that, by adsorption energy calculation, a strong interaction between TDM and ZnS (110) surface occurs, with the energy ⿿394.78 kJ/mol. The S 3p orbital on TDM interacted strongly with Zn 3d orbital on ZnS (110) surface, and electrons transferred from the Zn atom to the O atom, which resulted in a positive coordinate bond formed. Tertiary dodecyl mercaptan or TDM is a combination of isometric thiols obtained from oligomers of isobutylene trimer or propylene tetramer. Manufacturers pick one of these two and mix it with hydrogen sulfide, then pass the mixture over a catalyst like boron trifluoride to produce TDM. It has recently become a significant industrial chemical because of its use as a chain transfer agent in the manufacture of latex. As an agent, it helps in the polymerization of the end products. This role used to be given to chloroform, carbon tetrachloride, and other compounds of chlorine. However, their toxicity and negative ecological impact made the industry look for alternatives. This chemical also goes by the following names: tert-Dodecyl mercaptan, TERT-DODECANETHIOL, t-Dodecanethiol, Sulfole 120, tert-Dodecylthiol, CCRIS 6030, and t-DDM. It is used as an intermediate, as a process regulator, and as an additive to lubricants. This appears as a colorless liquid with a repulsive odor.
