  • Patent number: 8415502
    Abstract: A reaction column (12) to which a raw material mixture (11) containing a mono-lower-alkylamine (AA: raw material I) and an alkylene oxide (AO: raw material II) is supplied, an unreacted raw material distillation column (14) that separates an unreacted raw material (15) from a reaction product (13a) (containing the unreacted raw material (15), a target reaction product (monomer) (17), and a by-product (dimer) (18)), and a flash drum (16) to which a reaction product (13b) (containing the target reaction product (monomer) (17) and the by-product (dimer) (18)) is supplied, the flash drum (16) separating a mono-lower-alkyl monoalkanolamine (monomer, the target reaction product 17) in a gas state, are provided.
    Type: Grant

  • Patent number: 7977513
    Abstract: An amine producing apparatus includes a reactor that reacts a mono-lower-alkylamine and an alkylene oxide, an unreacted-raw-material-recovery distillation column that separates unreacted raw materials by distillation from a product including unreacted raw materials obtained in the reactor, a non-aqueous distillation column that removes water and a light component by a distillation method from a reactive product from which unreacted raw material have been separated, and a purification and distillation column that separates by distillation a desired reactive product (mono-lower-alkylmonoalkanolamine) and residue (mono-lower-alkyldialkanolamine which is a dimer) from a reactive product from which the water and the light component have been removed.

  • Patent number: 7732100
    Abstract: The invention provides a novel lithium-ion battery electrolyte which is produced by adding an aluminate ester compound as a plasticizer in a solid polymer electrolyte. The lithium-ion battery solid polymer electrolyte of the present invention comprises a lithium ion source, an organic polymer compound, and one or more kinds of aluminate ester compounds represented by the general formula where R1, R2, and R3 each independently represent a straight-chain or branched-chain lower alkyl group having one to eight carbon atoms, an alkenyl group having three to six carbon atoms, acryloyl, or methacryloyl; OA1, OA2, and OA3 each independently represent an oxyalkylene group having two to four carbon atoms; l represents a number from 1 to 100; and m and n each independently represent a number from 0 to 100.
