Linear absoiption

Reversible Reaction. This type of absorption is characterized by the occurrence of a chemical reaction between the gaseous component being absorbed and a component in the liquid phase to form a compound that exerts a significant vapor pressure of the absorbed component. An example is the absoiption of carbon dioxide into a monoethanolamine solution. This type of system is quite difficult to analyze because the vapor-liquid equilibrium curve is not linear and the rate of absoiption may be affected by chemical reaction rates. 

Hie samples possess narrow MW stributions. FTIR results indicate that these two-arm PEOs do not possess an absoiption band at 3500 cm which originates from hydrogen bonding and OH stretching vibration. The vibration band of the ketone group present in these PEOs is also observed at 1720 cm 17,18). WAXD patterns of the samples crystallized at different TqS show that die two-arm and linear PEO crystals possess identical structures. Therefore, the defects do not appear to change the crystal structure of the PEOs (77,18).
