WebFig. 6 A demonstrates the gravity-driven oil/water separation visually. The red and blue liquids are n-hexane and water, stained with oil red O and methylene blue, respectively. Since n-hexane has less density than water, it floats on the water after mixing. Leakage of liquid driven by gravity is not observed. WebMethylene diphenyl diisocyanate ( MDI) is an aromatic di isocyanate. Three isomers are common, varying by the positions of the isocyanate groups around the rings: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI. The 4,4′ isomer is most widely used, and is also known as 4,4′-diphenylmethane diisocyanate. [3] This isomer is also known as Pure MDI.
