THERMODYNAMICAL ASPECTS ON THE FREEZING MECHANISM OF AQUEOUS SOLUTIONS.

Author(s) : GONDA K.

Summary

TO ELUCIDATE THE MECHANISMS OF FREEZING, THERMODYNAMICAL PROPERTIES OF WATER AT LOW TEMPERATURES IN SOLUTION OF TETRAALKYLAMMONIUM BROMIDES, EMULSIONS, AND HYDROGELS HAVE BEEN INVESTIGATED AND THE RESULTS OBTAINED THROUGH FREEZING AND THAWING PROCESSES WERE COMPARED WITH EACH OTHER AS FREEZING MODELS OF BIOLOGICAL SYSTEMS. SEMI-MICROSCOPIC INTERACTIONS HAD RATHER MORE IMPORTANT ROLES THAN MICROSCOPIC INTERACTION WHICH WERE SO-CALLED SOLUTION EFFECT DUE TO DIRECT INTERMOLECULAR INTERACTIONS BETWEEN SOLUTE AND WATER MOLECULES. THREE DIFFERENT EFFECTS WHICH ARE A MOLECULAR SPACE EFFECT, A COMPARTMENTALIZED EFFECT AND A SHIELDING EFFECT HAVE BEEN CONSIDERED.
