Title:
COMPOUND PURIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/038968
Kind Code:
A1
Abstract:
A compound purification method according to the present invention comprises: a step for causing a solution that contains a solvent and a hydroxy-substituted aromatic compound represented by formula (A0) and/or formula (B0) to pass through a filter. (In formula (A0): n0 represents an integer of 0-9; m0 represents an integer of 0-2; p0 represents an integer of 0-9, wherein when m0 is 1, formula (A0) indicates that a naphthalene skeleton or a biphenyl skeleton is included therein; and each Ra independently represents a group selected from the group consisting of a hydroxyl group, halogen groups, linear, branched, or cyclic alkyl groups having 1-40 carbon atoms, aryl groups having 6-40 carbon atoms and optionally having a substituent group, or alkenyl groups having 2-40 carbon atoms, and the combinations thereof, wherein said alkyl group, aryl group, or alkenyl group may contain an ether bond, a ketone bond, or an ester bond. In formula (B0): n1 represents an integer of 0-9; p1 represents an integer of 0-9; and each Rb independently represents a group selected from the group consisting of a hydrogen atom, a hydroxyl group, halogen groups, linear, branched, or cyclic alkyl groups having 1-40 carbon atoms, aryl groups having 6-40 carbon atoms and optionally having a substituent group, or alkenyl groups having 2-40 carbon atoms, and the combinations thereof, wherein said alkyl group, aryl group, or alkenyl group may contain an ether bond, a ketone bond, or an ester bond.)
