Chemical-based methods and products for mitigating the impact of an oil spill are disclosed. The products act by herding, thickening, gelling, and reducing adhesiveness. N-fatty acid amino acid (FA-AA) conjugates display oil-herding behavior when formulated as a free acid in water-miscible organic solvents. A water-miscible organic solvent is not required if the FA-AA conjugate is formulated as a salt. Various salts of FA-AA conjugates are water soluble and can herd oils and increase the thickness of the oil layer. Replacement of the acid group of fatty acid α-amino acid conjugates with other groups that act as hydrogen bond donors and acceptors results in potent phase selective organo-gellants. The oil spill herders can be prepared from bio-based feedstocks and are biodegradable. The oil thickeners or gellants, which are prepared from bio-based feedstocks, have low toxicity, high capacity for oil and reduce the need to use an organic solvent to apply the thickener or gellant to the oil and water mixture in order to gel the oil phase.

本发明涉及化学方法和产品,用于减轻油污泄漏的影响。这些产品通过聚集、增稠、胶化和降低粘性来发挥作用。当N-脂肪酸氨基酸(FA-AA)共轭物被制成水溶性有机溶剂中的自由酸时,它们具有聚集油的行为。如果FA-AA共轭物被制成盐,则不需要水溶性有机溶剂。各种FA-AA共轭物的盐是水溶性的,可以聚集油并增加油层的厚度。将脂肪酸α-氨基酸共轭物的酸基替换为其他作为氢键供体和受体的基团,可以得到有效的相选择性有机胶凝剂。这些油污聚集剂可以从生物基原料制备,并且是可生物降解的。从生物基原料制备的油稠剂或胶凝剂具有低毒性,对油具有高容量,并且减少了使用有机溶剂将稠剂或胶凝剂应用于油水混合物以胶化油相的需要。公式(IB)、(II)、(III)。
