Sulfur Recrystalization
Hi,
I have recrystalized sulfur in the past in small quantities from ~50% sulfur fertilizer. I used white gas as the solvent because it is just naptha and
all the hardware stores in my area are out of xylenes right now. My first question is what is the solubility of sulfur in light naptha at the boiling
point (30c - 90c). My second question is about the impurities in the fertilizer. The other compounds are listed as: Iron Sucrate, Zinc Sucrate, and
Manganese Sucrate. I cant find anything about these compounds and the most information I can find is just other fertilizers with the same compounds.
The MSDS isnt helping either. They are somewhat soluble in water, and insoluble in naptha.
Thanks,
Jackson.

Light naphtha is a mixture of many hydrocarbons. I couldn't find any data on that specifically, but there is data on the solubility of sulphur in:
n-Hexane: 0.40 wt.% (g/100 g)
Cyclohexane: 1.185 wt.%
Benzene: 2.093 wt.%
at 298 K
Any ionic compounds will be fairly insoluble in hydrocarbon solvents. Those listed serve the purpose of being sources for iron, zinc, and manganese in
the fertilizer for plants.

I just Found out that they are most likely metal oxides because I was able to find an msds for another “sucrate” metal compound that listed it as
the metal oxide and calcium sulfate.

You can hot filter the S solution to remove any insolubles. Also is toluene available in your area?

Right now the OSH (which has most of the good stuff like sulfuric acid drain cleaner, toulene, acetone, xylenes, muriatic acid) is going out of
business and is completely out of any organic solvents. The home depot literally has nothing like that. I was just wondering what the insolubles were
because I wanted to know if they could be useful.
