摘要： PROBLEM TO BE SOLVED: To provide an analyzing method of a sulfoxide-type sulfur component in the sulfur component in insulating oil capable of simply measuring the sulfoxide-type sulfur component in the sulfur component contained in the insulating oil, with high sensitivity.
SOLUTION: The analyzing method of the sulfoxide-type sulfur component in the total sulfur component in the insulating oil has the process which uses a predetermined amount of the insulating oil as sample oil to pass the sample oil or a sample, which is prepared by making the sample oil dissolve in a non-polar solvent, through a silica gel, to make the sulfoxide-type sulfur component adsorb on the silica gel and the process for passing a polar solvent through the silica gel, to desorb the sulfoxide-type sulfur component from the silica gel and containing the desorbed sulfoxide-type sulfur component in the polar solvent. The sulfoxide-type sulfur component contained in the polar solvent is analyzed.

摘要： PROBLEM TO BE SOLVED: To provide a method for easily and rapidly determining rustproof oil that is applied to a metal material, metal products, and metal components for giving rustproofness and/or lubrication properties, and/or rustproof oil that is applied to the lubricant by a small amount of sample, and/or water in the lubricant. SOLUTION: An infrared transmission window material whose solubility to 100 g water at 20 deg.C is 1 g or less is used to measured rustproof oil and/or its infrared absorption spectrum, thus determining water from the ratio of the absorption intensity (peak are or peak height) of O-H bond appearing at a wavenumber of 3700-2800 cm , or the absorption intensity (peak area or peak height) of C-H bond in hydrocarbon appearing at a wavenumber of 3200-2800 cm , and the absorption intensity (peak area or a peak height) of O-H bond appearing at a wavenumber of 3700-2800 cm .

摘要： PROBLEM TO BE SOLVED: To provide a method of selecting a color pigment paste having excellent stability for fine aggregation of the color pigment which occurs during circulation of a paint, to provide a metallic paint obtained by using the method, to provide a method of forming a metallic film using the paint, and to provide a metallic film obtained by using the method. SOLUTION: An aromatic organic solvent, which is immiscible with the color pigment paste but is phase separated, is mixed with the color pigment paste containing at least the color pigment, a dispersing resin and an organic solvent, wherein the ratio of the solvent to a solid content of the color pigment paste is 1:20 to 3:1 (weight ratio). The extent in which the color pigment contained in the color pigment paste transfers from the color pigment paste phase to the aromatic organic solvent phase is used as the reference to test whether dispersing stability of the color pigment is good or bad to select the color pigment paste.
