Abstract:

Forty-seven chemicals were investigated to determine their usefulness as practical materials with which to form single-molecule-thick films that are capable of reducing the area covered by oil spilled on water. These chemicals are able to maintain the oil in a layer up to a maximum of approximately one-half inch thick by preventing it from spreading over the water surface. Such materials, classified as Collecting Agents by the National Contingency Plan, may be quite useful in increasing the efficiency of oil recovery devices, since all such devices perform better on thicker layers of oil. All materials investigated are commercially available in large quantities. Properties examined in this investigation included freezing points, viscosities, specific gravities, maximum film pressures achievable by the single-molecule-thick film, relative durabilities of materials in monomolecular layers confining oil on water in motion, and film pressures as a function of surface concentration of the monolayer forming materials.
