โœฆ Synopsis


The kinetics of chloroform extraction from a Jordan tar sand have been studied. The activation energy of the extraction has been evaluated; for 125-180 m tar sand it is 6โ€ข53 kJ mol\ in the initial stage of extraction and 12โ€ข18 kJ mol\ in the later stages, for 355-500 m 1โ€ข0 kJ mol\ and 10โ€ข61 kJ mol, respectively. These values are in agreement with the general activation energy of the dissolution of a solid material. It is concluded that the rate of extraction is controlled by the diffusion of extract.
