A reaction column () to which a raw material mixture () 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 () that separates an unreacted raw material () from a reaction product () (containing the unreacted raw material (), a target reaction product (monomer) (), and a by-product (dimer) ()), and a flash drum () to which a reaction product () (containing the target reaction product (monomer) () and the by-product (dimer) ()) is supplied, the flash drum () separating a mono-lower-alkyl monoalkanolamine (monomer, the target reaction product) in a gas state, are provided.

Method and apparatus for producing mono-lower-alkyl monoalkanolamine

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.

Method and apparatus for producing mono-lower-alkylmonoalkanolamine

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 R, R, and Reach 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; OA, OA, and OAeach 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.
