John, Gerald F. published the artcileEnhanced effectiveness of oil dispersants in destabilizing water-in-oil emulsions, SDS of cas: 111-87-5, the main research area is water oil emulsion stability dispersant.
Oil impacting the northern Gulf of Mexico shoreline from the 2010 Deepwater Horizon accident was predominantly in the form of water-in-oil emulsions (WOE), a chem. weathered, highly viscous, neutrally buoyant material. Once formed, WOE are extremely difficult to destabilize. Com.-available oil dispersants are largely ineffective de-emulsifiers as a result of the inability of dispersant surfactants to displace asphaltenes stabilizing the oil-water interface. This study investigated the effectiveness of the com.-available dispersant Corexit 9500A, modified to enhance its polar fraction, in destabilizing WOE. Results suggest that Corexit modified to include between 20-60% fractional amount of either polar additive (1-octanol or hexylamine) will produce a modest increase in WOE instability, with a Corexit to hexylamine ratio of approx. 80/20 providing the most effective enhanced destabilization. Results support the hypothesis that modifying the fraction of polar constituents in com. dispersants will increase asphaltene solubility, decrease oil-water interface stability, and enhance WOE instability.
