From measurements of the freezing-in temperatures (the 2nd-order transition temperatures) of soaps such as aluminium stearate, nickel stearate, cobalt stearate and aluminium laurate and from observations of the synereses of their greases, it has been perceived that the syneresis of a grease is mainly due to the gradual transition from a plastic form to a solid crystalline one of the corresponding dry soap. It has been found that the freezing-in temperature of a soap can be depressed by adding to it solid ketone such as stearone, tolyl-heptadecylketone, mesityl-pentadecylketone, and further that when a soap, of which the freezing-in temperature has been depressed below 0℃ by such an additive, is used for the preparation of a grease, the grease prepared is practically free from syneresis. A reasonable explanation for the mechanism of such syneresis-inhibiting action played by this kind of additives has been given. |
