摘要： The present invention addresses the problem of providing a flow reactor that is advantageously structured to increase the overall heat transfer coefficient, which represents the efficiency of heat exchange with respect to a reactive fluid to be treated. This flow reactor is provided with three flow passages, which are a first flow passage (11), a second flow passage (21), and a third flow passage (31) which spirally circulate within a space formed between an inner tube (61) and an outer tube (52). The flow passages are compartmented by an inner heat transfer body (41) and an outer heat transfer bodies. The heat transfer bodies spirally circulate, have a screw-like cross-sectional shape in an axial cross-sectional view, and are assembled in a screw-like configuration. By changing the shapes of a male-thread portion and a female-thread portion, the flow passage area of the first flow passage (11) is changed, the second flow passage (21) and the third flow passage (31) are spirally formed, and heat exchange and reaction take place through the heat transfer bodies.

摘要： The present invention relates to silicon-compound-coated fine metal particles, with which surfaces of fine metal particles, composed of at least one type of metal element or metalloid element, are at least partially coated with a silicon compound and a ratio of Si-OH bonds contained in the silicon-compound-coated fine metal particles is controlled to be 0.1% or more and 70% or less. By the present invention, silicon-compound-coated fine metal particles that are controlled in dispersibility and other properties can be provided by controlling the ratio of Si-OH bonds or the ratio of Si-OH bonds/Si-O bonds contained in the silicon-compound-coated fine metal particles. By controlling the ratio of Si-OH bonds or the ratio of Si-OH bonds/Si-O bonds, a composition that is more appropriate for diversifying applications and targeted properties of silicon-compound-coated fine metal particles than was conventionally possible can be designed easily.

摘要： The present invention addresses the problem of providing a method for modifying a fine particle dispersion liquid with which dispersibility and dispersion stability can be improved. By performing filtration to remove impurities in a dispersion liquid using a dispersion liquid modifying device provided with a removal unit that uses a filtration membrane, the quantity of impurities is reduced from a first region (1) until said quantity reaches a second pH-dependent region (2). In the second pH-dependent region (2), the dispersibility of the fine particles in the dispersion liquid is in a range in which the dispersibility depends more on a change in dispersion liquid pH than on a change in the quantity of impurities in the dispersion liquid. With the quantity of impurities reduced to the second pH-dependent region (2), the dispersibility of the fine particles is controlled by adjusting the pH of the fine particle dispersion liquid.
