• Solubility Studies
• Anti-Icing Performance Testing
• Recommendations

Background

• DiEGME is stored at various worldwide locations
  for extended periods of time under a wide range
  of storage conditions
• QS testing has revealed DiEGME degraded during
  storage
• Technical data on the effects of degraded FSII
  are limited

Off-Spec Color Investigation
10
Contamination Study on Bahrain Sample

• FTIR and GC/MS Analysis
• Plasticizers and/or Alkyd Resin Materials Found
• DiEGME is a strong solvent.
• Conclusion supported by other testing
• Readily soluble in DiEGME, but not in water
• Resin Materials also seen in 5-gal samples
  obtained by other supplier.

Impact of Alkyd Resin on Pt-Co Color
12
Antioxidant Impact on Pt-Co color
13
Impact of Iron on Pt-Co color
14
Off-Spec Color Findings

• Polymeric material contamination ( i.e. Alkyd
  Resin) was responsible for high level of Pt-Co
  color of Bahrain DiEGME sample
• Antioxidant degradation can also adversely impact
  Pt-Co color of DiEGME
• Dissolved Iron complexes will also degrade Pt-Co
  color of DiEGME

15
Solubility Injectability Studies
16
Solubility Studies

• Equilibrium Solubility and Dynamic mixing
  solubility
• Wet FSII impacts on Dry Fuel
• Dry FSII water level less than spec limit (0.1
  mass )
• Wet FSIIs 1, 1.5, 3, 5 vol water in FSII
• Dry Fuel Fuel with saturation level (65ppm) of
  total water
• Wet Fuels Fuels with 200 and 500ppm of total
  water
• Dry FSII impacts on Wet Fuel
• Wet FSII impacts on Wet Fuel

Recommended Use Limits
Request for waiver for Pt-Co color above 20 will
require additional testing and analysis to
determine if contamination is present.
