Mono-Substituted Cyclic Alkanes ZCR CH2 n

The adsorption data accumulated for these liquids [175] are collected in Table 14. If one assumes that steric hindrance is the only factor that needs to be considered in 

o was calculated by the method of component contributions in the manner outlined by Van Krevelen [27]. 

The correlations of Log az N for the cyclic series and for the corresponding acyclic series with N (Figs. 46-48) show that this is not the case. The set of az-N for the former are in each case uniformly much greater that those in the 

The above observation that otz N for the cyclic moiety is considerably greater than that of the corresponding linear moiety is not unique to ZCRR R molecules in which Z is phenyl of halogen. It appears instead to be a general phenomenon as indicated by the data collected in Table 16. 

The reason why the adsorption parameters, ac, for the cyclic molecules are significantly greater than those, ocL, for the corresponding linear molecules is not yet clear [175], There are at least four possible explanations (1) the cyclic moieties can pack more efficiently in a monolayer on or around a given adsorption site
