    Description / Table of Contents: Derivatives of Pentaerythritol, I.  -  Formaldehyde Bis(pentaerythrityl) Acetal and TetrapentaerythritolHerrn Prof. Dr. Wolfgang Lüttke zum 60. Geburtstag gewidmet.Pure formaldehyde bis(pentaerythrityl) acetal (9) and tetrapentaerythritol (4) were isolated for the first time as by-products during the synthesis of pentaerythritol from acetaldehyde and formaldehyde. The spectra show that 4 is not a branched molecule as suggested but a straight-chained one.
    Notes: Bei der Herstellung von Pentaerythrit aus Acetaldehyd und Formaldehyd wurden die Nebenprodukte Formaldehyd-bis(pentaerythrityl) acetal (9) und Tetrapentaerythrit (4) erstmals rein dargestellt. Die Spektren beweisen für 4 entgegen der bisherigen Annahme keine verzweigte, sondern eine lineare Konstitution.
