Title:
Method for separating perfluoro (poly) ether group-containing alcohol compound
Document Type and Number:
Japanese Patent JP6330960
Kind Code:
B2
Abstract:
The present invention provides a method for chromatographically separating a mixture comprising a perfluoro(poly)ether group-containing monoalcohol compound represented by the following formula (2) and a perfluoro(poly)ether group-containing dialcohol compound represented by the following formula (3):        A-Pf-Z ···     (2)        Z-Pf-Z ···     ((3)whereinPf represents a divalent perfluoropolyether group,A each independently represents an R- group, an R-O-group, an RO-CH-R- group, or an RO-CH-R-O- group,Reach independently represents an alkyl group,Reach independently represents an alkyl group,Reach independently represents a divalent organic group containing 1 to 4 carbon atoms,Z each independently represents an -R-CHOH group or an -O-R-CHOH group, andReach independently represents a bond or a divalent organic group containing 1 to 4 carbon atoms,the method comprising:adsorbing the mixture onto a stationary phase, andeluting the perfluoro(poly)ether group-containing monoalcohol compound represented by formula (2) by one mobile phase selected from the group consisting of hydrofluorocarbons, hydrochlorofluorocarbons, hydrofluoroethers, fluorine-containing ester solvents, and fluorine-containing aromatic solvents to separate the perfluoro(poly)ether group-containing monoalcohol compound represented by formula (2) from the perfluoro(poly)ether group-containing monoalcohol compound represented by formula (3).
