US companies purchase large quantities of fluorinated surfactants

With the drift of oil in the Gulf of Mexico in the United States, removing oil as soon as possible has become the most pressing issue in the United States. It is reported that fluorosurfactants can be used to enrich and remove oil from the Gulf of Mexico. It is understood that U.S. companies have already purchased fluorosurfactants on a large scale.

Fluorosurfactants are the most active of all surfactants. Fluorine is the most electronegative element, with high fluorocarbon bond strength and strong hydrophobic effect. The surfactant can greatly reduce the liquid surface tension and change the contact angle of water and oil. If the fluorinated surfactant is sprinkled on the oil-contaminated Gulf of Mexico, the oil will shrink inward when the oil meets the fluorosurfactant, so that the oil floating on the water will be enriched and thickened, and will not continue to Outside proliferation. When the oil is enriched to a very small extent, it can be salvaged and the oil on the sea surface can be removed.

It is understood that after the oil spill in the Gulf of Mexico on April 20, the US Air Force sprayed dispersants on the Gulf of Mexico to disperse the leaked crude oil. A month after the accident began, a total of approximately 582,000 gallons of dispersant was sprayed into polluted seas. The dispersant is a solution containing a surfactant. Once in contact with the oil, they will break down the oil into tiny droplets that will spread out and eventually be degraded by the bacteria. The use of dispersants reduces the possibility of oil contamination directly in contact with birds, fish, marine animals and shore-living plants. However, under certain conditions, it may increase the risk of sea creatures. Unlike attempts to decompose oil stains by the addition of chemicals, the use of fluorosurfactants does not contaminate the sea surface. Because the molecular structure of the fluorosurfactant determines that one of the fluorosurfactants is "lipophilic," one is "drip." In this way, the fluorosurfactant can uproot the oil, and it can be salvaged with the oil, which will not leave hidden dangers to the sea.

It is understood that the current global production of fluorinated surfactants is at the level of tens of thousands of tons. The world-famous fluorosurfactant companies are mainly concentrated in the United States, Europe and Japan, including DuPont and 3M, Belgium, Solvay and Daikin. According to market trends, there have been a number of U.S. companies and some multinational corporations starting to purchase large quantities of fluorinated surfactants.
