Abstract: A LKB 2107-030 sorption microcalorimeter has been installed and equipped with a microcomputer. The apparatus was tested with a standard reaction of TRIS and HCl. It was shown that this microcalorimeter is suitable for our proiect. A silica gel was chosen as a model surface for studying adsorption of surfactants used in enhanced oil recovery. A TG analysis of it was done and was used to select its activation temperature. The immersion heats of the silica into water, toluene and heptane were measured using this microcalorimeter. Before every experiment, silica sample placed in batch cell was activated at 170 ℃ and 10~(-2) mmHg. The results are generally in agreement with those recently obtained by Leo A. Noll and Thomas E. Burchfield.
