Aqueous and methanolic formaldehyde solutions are industrially important complex reacting mixtures in which formaldehyde is bound in a variety of oligomerization products. Reaction kinetics in these systems have to be taken into account in the design

In many technical processes, complex multicomponent mixtures have to be handled, for example, in reaction or separation equipment. High-resolution NMR spectroscopy is an excellent tool to study these mixtures and gain insight in their behavior in the

In the recent years, it has repeatedly been stated that amines react with CO2 and can therefore not be chromatographed under supercritical conditions with CO2. The aim of the present work is to elucidate the structural requirements and conditions tha
