Sauer, Joe D.,Elnagar, Hassan Y.,Fronczek, Frank R.
, p. o62-o64 (2003)
Crystalline N,N-dimethyl-n-tetradecylamine oxide has been prepared by reaction of liquid N,N-dimethyl-n-tetradecylamine with 70% H2O2 in the presence of CO2 as catalyst. The resulting soft low-melting solid was crystallized as the dihydrate, viz. C16H35NO·2H2O. The extended hydrocarbon chains pack in a parallel fashion, with the N-oxide ends of the molecules forming hydrogen bonds with the water molecules in hydrophilic layers. The N - O distance is 1.411 (3) A.
Process for preparing solid amine oxides
-
, (2008/06/13)
A solid amine oxide is prepared by reacting a tert-amine with at least a stoichiometric amount of an aqueous hydrogen peroxide having a concentration of at least 50% by weight in the presence as the reaction medium of a normally gaseous material which (a) has a critical temperature 160° C. and a critical pressure 12 MPa, (b) is in a liquefied, densified, or supercritical state in which it has a density of at least 0.1 g/cc, and (c) is present in an amount sufficient to maintain the reaction mixture stirrable throughout the reaction.
AMINE OXIDES-XIII IODINE COMPLEXES WITH NON-AROMATIC AMINE OXIDES

EDA-iodine complex with trialkylamine oxides in dichloromethane have been investigated spectrophotometrically.Thermodynamic (KADc,-ΔG0) and spectral (ΕADλ) characteristics of these complexes were determined.The absorption band of iodine in the visible region was blue-shifted with a variable maximum, depending on the structure of the amine oxide.The KADc and ΕADλ values were calculated using a modified method.A non-linear relationship KADc=(R), where R is the number of carbon atoms in the alkyl chain, was found.
