    摘要: A production process of acetic acid comprises a reaction step for continuously allowing at least one member selected from the group consisting of methanol, dimethyl ether, and methyl acetate to react with carbon monoxide in a catalyst system comprising a rhodium catalyst, an iodide salt, and methyl iodide in the presence of acetic acid and water in a plant compromising a reactor 1; a flasher 2; and a distillation column 3; wherein part of the vaporized stream is introduced into a heat exchanger 7. The process achieves a production of acetic acid with a high purity in a resource-saving and energy-saving equipment by efficiently removing a reaction heat even in a large-sized plant.

    摘要: A mixture containing hydrogen iodide and water and having a water content of not more than 5% by weight (particularly not more than 3% by weight) in a distillation system is distilled to prevent condensation of hydrogen iodide in the distillation system. The mixture may comprise hydrogen iodide, water, methanol, methyl iodide, acetic acid, and methyl acetate. Even when the mixture contains hydrogen iodide at a concentration of 1 to 3000 ppm on the basis of weight, an acetic acid product having a concentration of hydrogen iodide of not more than 50 ppm can be obtained by withdrawing a fraction containing hydrogen iodide from the top of the column, and withdrawing acetic acid as a side-cut stream or a stream from the bottom of the column. Such a process (distillation process) effectively inhibits condensation of hydrogen iodide in the distillation system and corrosion in the distillation system.

    摘要: A method produces acetic acid by continuously reacting methanol with carbon monoxide in the presence of a rhodium catalyst, an iodide salt, methyl iodide, methyl acetate, and water; and thereby producing acetic acid at a production rate of 11 mol/L·hr or more while keeping the acetaldehyde content of a reaction mixture to 500 ppm or less, in which the reaction is carried out at a carbon monoxide partial pressure in a gaseous phase of a reactor of 1.05 MPa or more and/or at a methyl acetate content of the reaction mixture of 2 percent by weight or more to thereby keep the production rate of acetaldehyde to 1/1500 or less that of acetic acid. This method can reduce production of by-products without reducing the reaction rate of acetic acid even at a low water content and a low hydrogen partial pressure in a reaction system.

    摘要: A disc-like grinding wheel 5 is formed with a circumferential groove 5a, the opposite walls of which define grinding surfaces 5b. A rotated carrier 3 brings a load pin 55 into rotary movement relative to the grinding wheel 5 rotated about an axis 5z, so as to pass the load pin 55 through space between the grinding surfaces 5b, whereby opposite end faces 55a of the load pin 55 are ground simultaneously. Thus, time taken by a grinding process may be reduced as compared with a conventional method wherein one end face is ground at a time.

    摘要: When carrying out magnetization, annealing, and initialization of a recording film by applying a laser beam to the recording film while rotating an optical recording medium 10 by a motor 11, light of a strong visible-light lamp 15 is projected as parallel light to a reflecting mirror 14 via a lens 16 so as to apply light reflected by the reflecting mirror 14 to an area wider than a spot of the laser beam on the medium 10 for heating. At that time, a control unit 18 controls an intensity of the strong visible-light lamp 15 to raise a temperature of the medium 10 to a temperature of 80° C. or higher and a softening point of a substrate or lower, for example.
