Chemical Composition and Structure of Gilsonite
Gilsonite is composed mainly of carbon (80-85%), hydrogen (10-12%), nitrogen, sulfur, and oxygen. This complex mixture of hydrocarbons contributes to its distinct solubility characteristics. Its high molecular weight and aromatic structure are significant factors influencing its behavior in different solvents.
Solubility in Organic Solvents
Gilsonite is notably soluble in several organic solvents, which facilitates its use in various industrial applications.
Aromatic Hydrocarbons
Gilsonite is highly soluble in aromatic hydrocarbons such as:
-
- Toluene
-
- Benzene
-
- Xylene
These solvents are commonly used to dissolve Gilsonite in the production of inks, paints, and coatings, due to their ability to break down the aromatic structures within Gilsonite.
Chlorinated Solvents
Gilsonite also shows good solubility in chlorinated solvents like:
-
- Trichloroethylene
-
- Perchloroethylene
These solvents are effective in industrial cleaning and degreasing applications, where Gilsonite’s solubility is an asset.
Limited Solubility in Aliphatic Hydrocarbons
Gilsonite has limited solubility in aliphatic hydrocarbons such as:
-
- Hexane
-
- Heptane
These solvents are less effective at dissolving Gilsonite due to their lower polarity compared to aromatic hydrocarbons.
Solubility in Water
Gilsonite is insoluble in water, making it hydrophobic. This property is advantageous for applications requiring waterproofing and moisture resistance, such as in road construction and sealants.
