I need to dissolve sulfur in mineral oil, in which it has low solubility.
Therefore, I am searching for an organic solvent that can dissolve sulfur and can be dissolved in oil. Preferably, an odorless solvent with low vapor pressure.3
Any idea?
Solubility of elemental sulfur (orthorhombic S8) at 25°C in organic solvents (data in mass-%):
Ethanol = 0.066
Acetone =0.079
Diethyl ether =0.181
Dimethyl formamide = 0.191
n-Hexane =0.40
Carbon tetrachloride = 0.832
Nitrobenzene =0.856
Chloroform =1.164
Cyclohexane =1.185
Aniline =1.259
Xylene = 2.051
Toluene = 2.070
Benzene = 2.093
Chlorobenzene = 2.370
Carbondisulfide =34.8
Gmelin Handbuch der Anorganischen Chemie, Schwefel, Teil A, Lieferung 3, VCH, Weinheim, 1953. M. Bamberg, Dissertation, Univ. Saarbrücken, 1959. Any water content will reduce the solubility of S8 while increasing temperature increases the solubility. At higher temperatures aniline is expected to react with S8, all other solvents are indifferent.

Of course the paper Prof. Shatzmiller referred to it is one of the best reference for your question. Just Shortly I could say, sulfur is mainly soluble in aromatic components. so any of those, like Toluene and benzene etc could be a good option.
In addition, depends on what you are looking on and T and P of your experiments, you can have it in super critical CO2 as well:

Thank you.
I need the sulfur to be soluble at 60C. The best solvent for now is quinoline, but it smells...
Dichlorobenzene is also good and has no smell (it dissolves about 10 wt% S at 60C).
I would like to find even better solvent for sulfur.
Try this paper please:
Solubility of elemental sulfur in pure organic solvents and organic solvent–ionic liquid mixtures from 293.15 to 353.15 K
Good luck
I was wondering what is the best organic solvent that can dissolve sulphur and be immiscible in water?
I wonder if it has solubility in any polar solvents to be used in HPLC. Pl. suggest
For what use?
I found that you can dissolve it in sodium methoxide by mixing sodium in methanol. However, this way it is not elemental sulfur anymore.
Hi Tomer Zidki,
This is related to estimation of sulfur at low level in reaction mass samples.
Among the solvents for solubilization of elemental S which will be safe for crop plants when sprayed as foliar fertilizer
Elemental S is moderately soluble in Acetone, Toluene, Benzene, Chloroform.....And solubility increases with temperature.
an addtional question: Due amines increase teh solubility of Sulfur? Due they react with sulfur?
what about amines?
¿¿Do they promote sulfur or sulfides dissolution??
Thanks, but I asked about amine dissolution of sulfur or sulfides. We observed amine attack of MnS and suppose that S passivation of the sulfitde is avoide by S dissolution .
yes, sulfur dissolve in carbon disulfide, if some body want to dissolve in other solvents like water then let me know, i have experience in this field.
I want to dissolve the sulfur in organic solvents and then do carbon coating
You may find useful to check the following somewhat related discussion: https://www.researchgate.net/post/Does_anyone_know_the_solubility_limit_both_are_nonpolar_molecules_and_seems_to_be_soluble_of_sulfur_S8_in_n-pentane
