    摘要: The claimed invention provides a novel compound not having been studied before, that is, a diene carboxylate anion that contains a specific structure, and a salt thereof. The claimed invention further provides a diene carboxylate anion and a salt thereof, especially a metal salt thereof, which are easily soluble in general organic solvents, reactive diluents, and resins, may be in a liquid state at normal temperature depending on the structure, and have high polymerizability. Polymerization/curing of these produces a resin to which many ionic bonds and a metal are introduced, providing various properties such as hardness, scratch resistance, anti-fingerprint property, gas-barrier property, water vapor barrier property, oxygen absorption property, ultraviolet protection, infrared protection, color development and coloring, high refractive index, adhesion, various catalytic abilities, fluorescence ability and light-emitting ability, optical amplification, dispersibility, and antistatic properties. In addition, the anion and the salt can be used for raw materials for functional fine particles and for metal nanoparticle composites, and also for MOD materials. The claimed invention also provides an advantageous method for producing the diene carboxylate anion and the salt thereof.

    摘要: The purpose of the present invention is to provide a means which can inhibit an ethylene oxide production process from yielding ethylene glycol as a by-product and can improve the yield of ethylene oxide. The ethylene oxide (EO) production process comprises the steps of feeding, to an EO absorption tower, an EO-containing reaction product gas produced in an ethylene oxidation step in which ethylene is subjected to catalytic vapor-phase oxidation with a gas containing molecular oxygen, in the presence of a silver catalyst, bringing the reaction product gas into contact with an absorbing liquid supplied to the absorption tower, feeding the EO-containing bottoms from the absorption tower to an EO purification system, and supplying the EO-containing uncondensed gas discharged from the purification system to an EO re-absorption tower, the re-absorption tower being operated at a pressure (tower top pressure) of 3-50 kPa gauge.

    摘要: An object of the present invention is to provide a simple method for improving and stabilizing the physical properties (for example, liquid permeability) of a water absorbent resin, without requiring investment in expensive facilities or modification of raw materials. In particular, the object is to provide a method which is useful in the large-scale production of a water absorbent resin. The method for producing polyacrylic acid (salt)-based water absorbent resin of the present invention includes, in order, a step in which an acrylic acid (salt)-based monomer aqueous solution is polymerized, a step in which the water-containing gel-like crosslinked polymer obtained in the polymerization step is dried, a step in which the dried polymer obtained in the drying step is pulverized, and a classification step which takes place after the drying step or after the pulverizing step, wherein, at the time of providing the dried polymer to the roll mill used in the pulverizing step, the dried polymer is provided in a dispersed state in the axial direction of the roll of the roll mill.
