The present invention relates to a novel chiral phase transfer catalyst and a method for producing alpha-amino acid using the same. It was confirmed that alpha-amino acid can be asymmetrically synthesized with high optical yield in reaction conditions which are easy to be used industrially by using novel cincho or alkaloid compounds as chiral phase transfer catalysts. Accordingly, alpha-amino acid can be used as a core technology in synthesis and manufacture fields of alpha-amino acid. COPYRIGHT KIPO 2017 ...

The present invention relates to an apparatus for treating discharged water in a water treatment process and a treatment method thereof. The apparatus includes: a supply unit for conveying and supplying raw water; an agglomerating unit for generating agglomerated substances by injecting an agglomerating agent to raw water; a film filtering unit which filters the raw water including the agglomerated substances with a film; a discharged water treatment unit for treating the water discharged from the film filtering unit; and a first input unit for inputting the sludge and discharged water from the film filtering unit to the discharged water treatment unit. Accordingly, the sludge generated in the film filtering unit used in the water treatment process is used to treat discharged water. The present invention enables the reuse of the sludge from the film filtering unit and reduces the concentration of contaminants in the discharge water while reducing the cost for treating the sludge waste and ...
