Gilsonite Molecular Structure
Gilsonite Molecular Structure – To know specific features of Gilsonite a diversity of sophisticated analytical tests have been run, to characterize its unique properties.
The test methods include vacuum:
- Thermal gravimetric analysis (TGA)
- Nuclear magnetic resonance (NMR)
- Fourier transform infrared spectrometry (FTIR)
- Vapor pressure osometry (VPO)
- High performance liquid chromatography (HPLC)
- Rapid capillary gas chromatography (RCAP)
And several fractionation techniques.
H/C ratios and NMR analysis, portend the attendance of a meaningful aromatic fraction. Most of the aromatics be in stable, inflected systems, probably porphyrin-like structures that relate to the geologic source of the product .The remainder of the product consists of long, paraffinic chains
The average molecular weight of Gilsonite is about 3000. This is very high relative to other asphalt products and to most synthetic resins. This may relate to Gilsonite’s “semi-polymeric” behavior when used as a modifying resin in polymeric and elastomeric systems. There is some reactive potential in Gilsonite. Crosslinking and addition type reactions have been observed. Gilsonite is known to react with formaldehyde compounds under certain conditions. Its unique chemical and physical properties make Gilsonite a high-performance, multipurpose additive that is also a cost-effective solution.
