Which surfactant or the combinations of surfactants would be suitable for ethanol-water-diesel blending?
MR. TIHOMIR, WHAT SHOULD BE THE BASIS FOR SELECTING SURFACTANT? CAN YOU PROVIDE SOME GOOD EXAMPLES SUITABLE FOR MY APPLICATION?
You can find some suitable surfactants by considering their HLB values.
MR. ATTHAPHON, CAN YOU TELL ME WHAT HLB RANGE IS SUITABLE FOR MY BLENDS APPLICATION? CAN YOU PROVIDE SOME LITERATURE REGARDING THIS?
It depends on the fraction of diesel to ethanol you have.
If you have small fraction of ethanol in diesel, you may first try SPAN 80 due to its good ability to disperse water (or polar phase) in diesel (says water in oil emulsion).
Vice versa, you may try Tween 80 for oil in water emulsion.
Both dispersants are popular nonionic surfactant!
A priory seems to me that you should either try blending diesel with water and higher dosage of ethanol (cosolvent) or preparing 'stable' emulsions with surfactants, preferably of low HLB. I would expect antagonistic effect of ethanol/surfactant combination.
MR. TITUS, I AM PLANNING 10% ETHANOL, 9% WATER, 1% SURFACTANT, 80% DIESEL MIXING. CAN YOU EXPECT GOOD RESULTS? PLEASE ELABORATE. WHAT DO YOU MEAN BY ANTAGONISTIC EFFECT? WHAT DO YOU THINK ABOUT FEASIBILITY OF THIS? CAN YOU PROVIDE ANY LITERATURE REGARDING THIS?
