A gas chromatographic technique has been successfully developed for the measurement of Tertiary Dodecyl Mercaptan 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) Tertiary Dodecyl Mercaptan 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, chlorinated compounds 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.

Highlights of Tertiary Dodecyl Mercaptan:
-Tertiary Dodecyl Mercaptan is an effective collector for sphalerite with less CuSO4 and without frother.
-Tertiary Dodecyl Mercaptan chemisorbs on the minerals surface.
-Adsorption modes of Tertiary Dodecyl Mercaptan on mineral surfaces are obtained by first-principle study.
-Absorption energies of Tertiary Dodecyl Mercaptan on ZnS (110) and FeS2 (100) are ⿿394.78, ⿿219.33 kJ/mol.
-Reactions happen between S 3p orbital of Tertiary Dodecyl Mercaptan 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 Tertiary 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 Tertiary Dodecyl Mercaptan with sphalerite has been investigated by adsorption measurement, fourier transform infrared (FTIR) and density functional theory (DFT).
It is showed that, Tertiary Dodecyl Mercaptan 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 Tertiary Dodecyl Mercaptan and sphalerite is determined by analyses of frontier orbital energy calculation.
It is also indicated that, by adsorption energy calculation, a strong interaction between Tertiary Dodecyl Mercaptan and ZnS (110) surface occurs, with the energy ⿿394.78 kJ/mol.
The S 3p orbital on Tertiary Dodecyl Mercaptan 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 Tertiary Dodecyl Mercaptan 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 Tertiary Dodecyl Mercaptan.

As an agent, Tertiary Dodecyl Mercaptan 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.

Preparation of Tertiary Dodecyl Mercaptan:
12 grams of water and 40 grams of dodecene were introduced into the plant through a funnel.
After the factory is sealed, the reaction mixing pump is put into operation (speed: 2800min-1), and then the entire pumping cycle system (including the pump head) manufactured in the jacket design is restored to the initial temperature.
The reaction is started by gradually injecting the first 10 bar of carbon dioxide, and then gradually injecting 20 bar of hydrogen sulfide gas to a total pressure of about 30°C. 31 bar.
During the experiment, the H2S feed of the reactor system was kept open so that the amount of reacted hydrogen sulfide could be replenished into the reaction system.
During the next 2 hours, the mixture was uniformly heated to 60°C.
After another 3 hours, all dissolved gas components are removed from the biphasic liquid sample by decompressing at the discharge valve and further heating to 100°C.
The composition of the organic liquid phase (upper phase) is analyzed by gas chromatography, and it is possible to distinguish the reactants (olefins), the main products (tert-dodecyl mercaptan), and the minor components (thioethers).

The kinetic of consumption of Tertiary Dodecyl Mercaptan (TDM) in emulsion polymerization of chloroprene in the presence of various amounts of sulphur have been studied.
Tertiary Dodecyl Mercaptan is shown that during the entire course of polymerization of chloroprene the relative rate of consumption of TDM increases as the concentration of sulphur, the second regulator, is increased.
Increase in the degree of conversion and decrease in the concentration of sulphur cause an increase in the molecular weight and in the breadth of the molecular weight distribution of the polymer.
A molecular mechanism of control of the MWD and average molecular weight of polychloroprene by this combined regulator system is proposed.
