2- Ethyl-l-butene

Effect noted experimentally, but data insufficient to quantitate. r Includes measurements on propylene through 1-hexene, 2-ethyl-l-butene, and 2,4,4-trimethyl-l-pentene. 

In 2-ethyl-l-butene, the double bond and the branch are near each other on the carbon chain. What happens if the double bond is close to one end of the carbon chain, but the branches are close to the other end For example, how would you name the compound in Figure 13.21 ...

However, the extent of facilitation and the magnitude of the flux value are not constant for each alkene permeate. The facilitation factors are similar for both 1-hexene and 2-ethyl-l-butene signifying that the complexation reaction for these two molecules are very similar. The transport of 2,4,4-trimethyl-l-pentene exhibits both a lower flux and lower facilitation factor tiian for 1-hexene or 2-ethyl-l-butene. The reduced flux can be explained by the inaease in molecular size causing lower physical solubility and slower diffusion in the hydrated membrane. These effects are also reflected in the fluxes through Na+-form membranes. Alkane flux is dependent only upon solubility and diffusion in each membrane form. Similar alkane fluxes are observed for the Ag+- and Na+-exchanged membranes.
