Hydrocarbon spring saturated

Table VIII. Group-type Analysis of P.R. Spring Saturated Hydrocarbons...

The adsorption-desorption isotherms of benzene, cyclohexane, 2,2-dimethylbutane (2,2-DHB) and isooctane were determined at 298K in a grease-free gravimetric system using silica spring balances (ref. 4). For each experimental point an "equilibrium" time of Ih was allowed for all hydrocarbons (4h for the first point) except for isooctane (4h for each point and 24h for the first). Before proceeding to desorption the system was held under saturation conditions for 60h and an "equilibrium" time of 3h was then used for each desorption point.
