ABSTRACT:
Phosphonium salts are prepared by reacting polydentate phosphines containing two or more trivalent phosphorus atoms with alkyl or aralkyl halides. Treatment of glass surfaces and glass capillary columns with these salts substantially eliminates tailing of peaks and allow the high temperature separation and characterization of polar compounds by gas chromatography at temperatures of 300.degree. C.
