- n. A colorless compound, CH3(CH2)14CH3, containedin petroleum. It forms pearly lustrous leaflets, which melt at 19–20° C. and boil at 287.5°C. Sometimes called cetane.
An oily substance called hexadecane beads up on this new type of membrane created by Purdue materials engineers to separate oil from water.
The findings demonstrate how an oily substance called hexadecane beads up on the membrane while water passes through.
When hexadecane (oil) 'sees' the oleophobic perfluorinated end of the polymer, it beads up, he explains.
To date, the researchers have only tested diesel or hexadecane fuel but the team has plans to test other oils such as benzene toluene zylene. research team led by chemical engineer Robert Cohen and mechanical engineer Gareth McKinley has created what it claims are the first "superoleophobic," or oil-repellant surfaces.
The team has now found that enzymes within the microbial cell and in its membrane inner membrane are responsible for degradation of n-hexadecane.
Water (dyed blue) and hexadecane (dyed red), an oil, bead up on an omniphobic surface, which repels all liquids.
This mat is coated with a fluorinated polymer and acts like a bed of nails that can support droplets not only of water (dyed blue), but also of oil (hexadecane, dyed red).
Taking these observations, the team designed and manufactured surfaces that effectively repelled droplets of oily liquids such as methanol, octane and hexadecane.
