Abstract:
AbstractAfter earlier work in this laboratory on lower hydrates of amines, the melting diagram of the system 1,8-diaminooctane/water and six new crystal structures of hemi- and monohydrates of terminal primary n-alkylamines and diamines have been determined. In the hydrates 1 -PrNH2 · 0.5 H2O (space group C 2/m with Z = 4 formula units per unit cell), l-HexNH2 · 0.5 H2O (PI, Z = 2) and H2N(CH2)nNH2 · H2O with n = 4, 6, 8 (P 2x/c, Z = 4), the O and N atoms are hydrogen-bonded into a two-dimensional array analogous to the mutual coordination of cations and anions in the Cdl2 structure type: [ON6/3] ~ [CdI6/3]. In the hydrate H2N(CH2)2NH2 · H2O (C 2/c, Z = 4), the H2O/NH2 partial structure is three-dimensional but can be reduced, by neglecting the longest H bond, to an array which is again just two-dimensional and related now to the red Hgl2 structure type: [ON4/2] ~ [HgI4/2], In all the monohydrates, the arrays as defined are crosslinked by the alkylene cnains of the bifunctional amine molecules

Abstract:
The polarizabilities of some primary, secondary, and tertiary amines have been calculated with the MINDO/3-FP-method. The calculated values are found to correlate with the experimental polarizabilities and with those determined by the method of Miller and Savchik in a satisfying manner. In addition atomic polarizabilities have been calculated according to the method of Metzger. Averaging over the calculated mean atomic polarizabilities of hydrogen, carbon, and nitrogen yields increments which, when used to recalculate molecular polarizabilities, lead to values which correlate in an excellent manner with those determined from densities and refraction indices by means of the Lorenz-Lorentz-equation.Because different nitrogen increments have been determined for primary, secondary and tertiary amines, the parameters presented here make it possible to distinguish between constitutional isomers as long as they belong to different groups (i.e. primary, secondary, and tertiary amines), something which cannot be done using the method of Miller and Savchik. The increments derived do not only allow to predict the polarizabilities of primary, secondary and tertiary amines but can be used to calculate the corresponding values for hydrazines and polyfunctional amines with equal success.

Abstract:
Our investigations concerning the protonaffmity of aliphatic amines have been confined so far to primary unbranched species. In order to gain further information about the applicability and the limitations of the statements derived from the results of the previous calculations, we extended our investigations to some tertiary, secondary and branched primary amines. Correlations between the experimental protonaffinities and the Mulliken charges of the nitrogen atom and the NHx-group (x = 0, 1, 2) of the amines, as well as those of the NHx + 1 ,-group of the corresponding ammonium cations have been found. However, these correlations only hold within the different groups of amines (primary, secondary and tertiary) and not between them. A somewhat better correlation throughout all groups is found if one compares the charges of the protons in the NHx + 1-groups of the ammonium cations with the experimental protonaffinities of the parent amines but deviations from the expected order are found in this case, too. This shows the limited value of charges as calculated by the methods used here, in predicting the relative order of protonaffinities of amines if they belong to different groups.

Abstract:
The toxicity of 36 aliphatic amines on the embryos of the zebrafish Danio rerio were investigated. The DarT (Danio rerio Toxicity assay) was used to determine the lethal concentrations within a 48 h static acute toxicity test. A QSAR (Quantitative Structure-Activity Relationship) was performed using the LC50 values and molecular descriptors such as lipophilicity, maximum positive charge on hydrogen atom and the effective diameter of the molecule. In general, the toxicity of primary and secondary amines could be described by the lipophilicity as descriptor. The toxicity of the tertiary amines tested could be only described by a bilinear regression model. Further, regression models for other aquatic species such as the fathead minnow Pimephales promelas, Daphnia magna and Tetrahymena pyriformis showed that the toxicity of each species is a good predictor for each other.

Abstract:
Der nachwachsenden Rohstoff Cellulose stellt mit einer geschätzten Biosyntheserate von 180 Milliarden Tonnen das meistvorkommende Biopolymer dar. Ein neuartiges Verfahren zur Verarbeitung von Cellulose, das Lyocell- oder Aminoxid-Verfahren verzichtet auf den Einsatz von umweltgefährdenden Lösemitteln. In diesem Verfahren wird Cellulose in einer Schmelze eines aliphatischen Amin-N-oxid-Monohydrats gelöst und durch Ausfällen in einer verdünnten wässrigen Aminoxid-Lösung regeneriert. Im technischen Prozess wird N-Methylmorpholin-N-oxid (NMMO) eingesetzt. Nicht alle aliphatischen Amin-N-oxide besitzen ein gleichermaßen gutes Lösevermögen für Cellulose, selbst innerhalb einer homologen Reihe aliphatischer Amin-N-oxide treten Sprünge im Lösevermögen für Cellulose auf, die nicht mit einer molekularen Eigenschaft der Aminoxide korreliert werden können. Ziel dieser Arbeit war es daher, das unterschiedliche Löseverhalten von Cellulose in aliphatischen Amin-N-oxiden mittels der Methode der Molekulardynamik-Simulation zu untersuchen. Zunächst wurde zur Validierung des verwendeten Kohlenhydrat-Kraftfeldes eine Simulation kristalliner Cellulose der Modifikation Cellulose II in antiparalleler Kettenorientierung zur Bestimmung des Elasitizitätsmoduls in Faserrichtung (Young-Modul) durchgeführt. Der Vergleich mit Ergebnissen von Reiling et al. zu einem Modell von Cellulose II in paralleler Kettenorientierung und experimentell ermittelten Young-Moduln gibt Anlass, eine parallele Kettenorientierung für mercerisierte Cellulose (Cellulose II) anzunehmen. Zur Untersuchung des Löseverhaltens wurden Molekulardynamik-Simulationen zweier ternärer-Systeme, eines Lösemittelsystemes (NMMO-Monohydrat) und eines Systems, das kein Lösevermögen für Cellulose besitzt (N,N,N-Trimethylamin-N-oxid-Monohydrat, TMAO-Monohydrat) durchgeführt. Die Untersuchung struktureller (radiale Paarverteilungsfunktionen, Anzahl und Struktur von Wasserstoffbrückenbindungen, N-Oxid-Sauerstoffpopulationen) und dynamischer (Diffusionskoeffizienten) Eigenschaften der Systeme ergab für NMMO im Gegensatz zu TMAO eine chelatartige Anlagerungsstruktur um das Cellohexaose-Molekül, in der die Ausbildung von zwei Wasserstoffbrückenbindungen zu beiden sekundären Hydroxylgruppen der Anhydroglucoseeinheit möglich ist.
