  • Patent number: 10696621
    Abstract: The present invention relates to a novel chiral phase-transfer catalyst, and a method for preparing an alpha-amino acid by using the same. According to the present invention, an alpha-amino acid of high optical purity could be synthesized in a high yield under an easy industrially applicable reaction condition by using a novel cinchona alkaloid compound as a chiral phase-transfer catalyst, and thus the present invention can be used as a key technique of the asymmetric alpha-amino acid synthesis and preparation field.

  • Publication number: 20140377453
    Abstract: The present invention relates to an insulating adhesive composition for metal printed circuit board, an adhesive-coated metal plate using the same, and a method for manufacturing the adhesive-coated metal plate. The adhesive composition according to the present invention forms an adhesive layer that is excellent in terms of adhesion to a copper foil, electrical insulating properties, and thermal resistance. The composition contains a specific epoxy resin, a curing agent and alumina. According to the present invention, in coating the metal plate with the solvent type adhesive, a roll coating method is used to perform a continuous coating process on the metal plate, thereby improving productivity when compared to the general method using a sheet type adhesive film.
