摘要： PROBLEM TO BE SOLVED: To obtain a metal copper catalyst for synthesizing organohalosilane having large strain energy and comprising a thermally active metal copper powder. SOLUTION: By using a highly active copper catalyst having large internal strain energy, an activating time required until a steady state is obtained having being a problem in reaction for allowing a metal silicon powder to directly act on organohalide to synthesize corresponding organoholosilane is shortened and selectivity can be improved in the steady state and the yield of silicon can be enhanced. Since the copper catalyst is important, it is industrially used heretofore after the activity thereof is evaluated by separately executing a test by actually using the same as a reaction catalyst but this roundabout process problem can be also solved.

摘要： PROBLEM TO BE SOLVED: To directly measure the surface stage of the solid particle of an inorganic support material being blended into a compound by using the dipole element-dipole element decoupling method and the cross polarization method for improving sensitivity by magnetizing protons by pulses. SOLUTION: The solid surface of a support material in a compound where an inorganic support material is contained into siloxane is measured by a method. By using the dipole element-dipole element decoupling method and the cross polarization method for magnetizing protons by pulses and improving sensitivity together, a solid Si-NMR analysis is made, the interface stage between a silica surface and a base oil for the blend system of the inorganic support material such as various kinds of silica can be directly measured and a remaining polar group is directly measured as an active point in a mixture system based on the application. Therefore, the measurement method is effective for an evaluation technique, for example, for a quality design, a quality control, and a trouble analysis.

摘要： PURPOSE:To produce, at a high yield under mild conditions, a polysilane which exhibits a high electric conductivity when doped and is suitable as a photoelectric conversion material or a conductive material by subjecting a specific trihydrosilane to condensation by dehydration. CONSTITUTION:A trihydrosilane of formula I [wherein X is halogen, alkyl, fluoroalkyl, alkoxy. (substd.) amino, acyl, or an aldehyde group; Y is H, halogen, alkyl, fluoroalkyl, (substd.) amino, acyl, or an aldehyde group provided that X and Y may combine with each other to form an alkylene or heteroalkylene group and that when Y is H, then X is not alkyl nor fluoroalkyl; m is 1-5; and k is 0-4 provided k+m is 1-5] is subjected to condensation by dehydration to give a polysilane of formula II (wherein X, Y, m, and k each is the same as described above; and n>=3). Thus, a polysilane exhibiting a high electric conductivity when doped and suitable as a photoelectric conversion material, an electric conductive material, etc., is obtd. at a high yield under relatively mild conditions.

摘要： PURPOSE:To quantitatively determine the silicone in the space by extracting the org. silicon compd. (silicone) in the air absorbed on an adsorbent by an org. solvent and thermally decomposing the extracted silicone, then determining the resulted product of the thermal decomposition. CONSTITUTION:The silicone existing in the air is absorbed on the adsorbent powder. The silicone adsorbed on the adsorbent is extracted by the org. solvent and the extracted silicone is thermally decomposed and the resulted product of the thermal decomposition is determined. The adsorbent to be used is exemplified by active carbon, silica gel, active alumina, etc. and the grain size thereof is preferably about several mum to several 100mum. Among these adsorbents, the active carbon is most adequate. For example, carbon tetracholoride, hexane, methyl isobutyl ketone, 'Freon-113', etc., are usable as the org. solvent to be used for the extraction.
