Abstract: Provided are a pressure medium oil, containing a Group-14 element-containing organic compound selected from an organic germanium compound, an organic tin compound, and an organic lead compound, and a method for using a pressure medium oil, which includes applying a pressure to a substance via the pressure medium oil. The pressure medium oil does not solidify even under an ultrahigh pressure of more than 3.7 GPa at room temperature (25° C.) and has a low pour point, and hardly dissolves a conductive paste.

Abstract: A pressure medium containing at least one Group-14 element-containing organic compound (A) selected from the group consisting of a compound (A1) represented by the general formula (a1) and a compound (A2) represented by the general formula (a2):




where each of Ra11, Ra12, Ra13, and Ra14 independently represents an alkyl group having 3 to 6 carbon atoms, and Za1 represents a carbon atom or a silicon atom:




where each of Ra21, Ra22, Ra23, and Ra24 independently represents an alkyl group having 3 to 6 carbon atoms, and Za2 represents a silicon atom, a germanium atom, a tin atom, or a lead atom.
