Abstract
Von Fettalkohol‐Ethylenoxid(EO)‐Addukten H(CH2)n(OCH2CH2)mOH werden flüssigchromatographisch die EO‐Polymerhomologenverteilung durch Anwendung einer Lichrosorb‐NH2‐Säule und n‐Heptan/Tetrahydrofuran als Eluent und die Alkylkettenlängenverteilung mittels Lichrosorb‐RP8‐Säle und Methanol/Wasser bestimmt. Es werden Hinweise zur quantitativen Bestimmung der n‐ und m‐Adduktfraktionen einschließlich des PEG‐Anteils und Anregungen zur Erfassung der chemischen Individuen gegeben.Keywords
