Provided is a method for producing an oxide and/ or hydroxide characterized in that the ratio of oxide and hydroxide has been controlled. The method produces an oxide, a hydroxide, or a mixture thereof, and obtains an oxide and/ or a hydroxide characterized in that the ratio of oxide and hydroxide has been controlled by means of changing a specific condition relating to at least one fluid to be processed introduced between processing surfaces (1, 2) when causing the precipitation of the oxide, hydroxide, or mixture thereof by mixing an basic fluid containing at least one type of basic substance and a fluid containing at least one type of metal or metallic substance as the fluids to be processed between the processing surfaces (1, 2) that are provided facing each other, are able to approach to and separate from each other, and of which at least one rotates relative to the other. The specific condition is at least one condition selected from the group consisting of: the speed of introduction of at least one of the fluids to be processed; and the pH of at least one of the fluids to be processed.

The present invention addresses the problem of providing a method for producing a high-quality barium titanyl salt. This method includes: using, as the fluids to be treated, at least two kinds of fluids, namely, a barium titanium mixed solution that is obtained by dissolving both a barium compound and a titanium compound in a solvent, a compound solution that is obtained by dissolving, in a solvent, a compound capable of deposing the barium and titanium contained in the barium-titanium mixed solution into a barium titanyl salt, and if necessary, one or more other fluids; and mixing these fluids together in a thin film fluid formed at least between two treating surfaces (1) and (2) to form a barium titanyl salt. The treating surfaces (1) and (2) are so arranged as to face each other in an approachable/ separable state with one of the treating surfaces (1) and (2) being capable of turning relatively to the other. In the method, an acid substance is added to the barium-titanium mixed solution, the compound solution, and/ or a third solvent which is neither the barium-titanium mixed solution nor the compound solution, whereby a barium titanyl salt having a controlled barium/ titanium ratio can be obtained.

The object of the present invention is to provide a method for producing a resin microparticle aqueous dispersion, which can produce monodisperse resin microparticles, does not cause clogging by a product, does not require a high pressure, and hasahighproductivity. Thus, provided is a method for producing a resin microparticle aqueous dispersion, wherein a fluid having at least one kind of resin dissolved in a solvent with which a resin is soluble and compatible and a fluid of an aqueous solvent join together in a thin film fluid formed between processing surfaces arranged opposite so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, whereby resin microparticles are obtained in the thin film fluid by way of separation/emulsification.

A method for producing isolatable oxide microparticles or hydroxide microparticles using an apparatus that processes a fluid between processing surfaces of processing members that are arranged opposite each other so as to be able to approach to or separate from each other and such that at least one can rotate relative to the other. Using an apparatus that processes a fluid between processing surfaces (1 and 2) of processing members (10 and 20) that are arranged opposite each other so as to be able to approach to or separate from each other and such that at least one can rotate relative to the other, at least two fluids are mixed and oxide microparticles or hydroxide microparticles are separated, said two fluids including: a fluid containing a microparticle raw material solution comprising a microparticle raw material mixed into a solvent, and a fluid containing a microparticle-separation solution. Immediately thereafter, the following are mixed to obtain isolatable oxide microparticles or hydroxide microparticles: a fluid containing the separated oxide microparticles or hydroxide microparticles; and a fluid containing a microparticle-treatment-substance-containing solution that contains a microparticle-treatment substance that adjusts the dispersibility of the separated oxide microparticles or hydroxide microparticles.

Provided is a method for producing separated substances, particularly metal compounds, the dopant element amounts of which have been controlled by the use of an apparatus that processes fluid between the processing surfaces of a processing member that can be made to approach/separate and which rotate relative to each other. Using the apparatus that processes fluid between the processing surfaces 1 and 2 of the processing member that can be made to approach/separate and which rotate relative to each other, the substance to be separated is separated by mixing a raw material solution, wherein the substance to be separated is solubilized in a solvent, with the solvent for separation and with the dopant element or dopant element-containing substance solubilized in at least one solvent selected from the solvent of said raw material solution, said solvent for separation or a solvent other than that of said raw material solution or said solution for separation. Separated substances with controlled dopant element amounts are obtained by controlling the solubility of the dopant element or dopant element-containing substance in the solvent for separation.

Disclosed is a heat exchanger which is small and can efficiently exchange heat, and can be produced at low cost in comparison with a conventional heat exchanger. In the heat exchanger, a heat-transfer tube through which a fluid to be processed passes can be easily replaced so that the heat exchanger can be used for a treatment which requires a low flow rate, especially, in various kinds of chemical experiments. A heat-transfer tube (1) produced in the form of a coil is attached to, for example, a lower closing portion (8) and an inner tube (5), which are integrally produced. After that, the heat-transfer tube (1) is pulled in the U-direction to reduce the diameter of the coiled portions and, thus, is closely bonded or welded to the inner tube (5). After that, an outer tube (6) and an upper closing portion (9) are attached so that there is a slight gap between the outer tube (6) and the outer diameter of the heat-transfer tube (1). A fluid (2) to be processed is passed through the heat-transfer tube (1). A heat medium is passed through a space (7) and a coiled space (4) to efficiently exchange heat. The space (7) is defined between the inner and outer tubes (5) and (6) and closed by the upper and lower closing portions (8) and (9). The coiled space (4) is defined between the coiled portions of the heat-transfer tube (1). The heat exchanger can be easily disassembled in the reverse order of the above procedure, and the heat-transfer tube (1) can be easily replaced.
