Abstract

The adsorption of acetone, methyl-ethyl ketone, diethyl ketone, ethyl formate, ethyl acetate, n-propyl acetate and methyl propionate by activated charcoal has been measured for temperatures between 0° and that of decomposition. The Langmuir isotherms, obtained by plotting p/x/m against the pressure p, are rectilinear at the lower temperatures and up to 60 mm. pressure. At higher temperatures and pressures the isotherms tend to deviate from the straight line and bend toward the pressure axis. The amount of vapor adsorbed per gram of charcoal decreases with increase in the complexity of the adsorbed vapor molecules; further it is found to decrease with increase in the value of the van der Waals constant, b.
