摘要： PURPOSE: To analyze oxygen contained in an organic substance with high accuracy and with high speed by energizing a carbon crucible before throwing a sample in so as to bring the crucible in a predetermined high temperature state, and throwing the organic substance sample in the high temperature carbon crucible. CONSTITUTION: Before throwing an organic substance sample in a carbon crucible 2 in an extraction furnace 1, the carbon crucible 2 is energized so as to bring the carbon crucible 2 in a predetermined high temperature state, and the organic substance sample is thrown in the high temperature carbon crucible 2. The organic substance sample is heated by energizing, generated gas is led to a gas analyzer 4 so as to measure the concentration of carbon monoxide, and based on the concentration of the carbon monoxide contained in the organic substance sample so as to analyze oxygen contained in the organic substance sample. By this method, the organic substance sample is thrown in the heated carbon crucible 2 so that vaporization components at a low temperature, a middle temperature, and a high temperature are generated approximately simultaneously. The generated vaporization components are thermally decomposed by the high temperature carbon crucible 2, and is further reduced by high temperature carbon so as to become CO surely. A capture rate is thereby heightened so that the measuring accuracy is improved.

In this way, the silicon metal particles coated with a thin film comprising the copper compound or comprising the copper compound and a cocatalyst compound, or fine spot-shaped thin films comprising the compound are produced efficiently in a simple process. By using the particles as a catalyst of an exposure reaction for synthesizing an organohalosilane by reacting an organic halide with the particles, an activation time required for the reaction can be shortened, the deterioration of activity can be reduced, and the life of a catalyst body can be extended.
