A study of condensation of propane-1,3Diamine with formaldehyde

Abstract

The condensation of formaldehyde with propane-1,3-diamine gave four products depending on the conditions of the reaction of them dimer, trimer, tetramer and pentamer of N,N΄-bis(methylene)propane-1,3-diamine products (CH2=NCH2CH2CH2N=CH2). Their structures were determined by MS, elemental analysis and 1H NMR spectroscopy methods. The structure of the pentamer was additionally determined by X-ray diffraction analysis.
