ATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE

The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...

Phase transition in the n > 2 honeycomb O(n) model

We determine the phase diagram of the O(n) loop model on the honeycomb lattice, in particular, in the range n>2, by means of a transfer-matrix method. We find that, contrary to the prevailing expectation, there is a line of critical points in the range between n = 2 and infinity. This phase transition, which belongs to the three-state Potts universality class, is unphysical in terms of the O(n)...

N-(2-Chloro­eth­yl)morpholine-4-carbox­amide

The title compound, C7H13ClN2O2, synthesized by the reaction of 2-chloro-ethyl iso-cyanate and morpholine, crystallizes with four molecules in the asymmetric unit, which have similar conformations and comprise two pairs each related by approximate non-crystallographic inversion centres. Two of them have a modest orientational disorder of the 2-chloro-ethyl fragments [occupancy ratio of 0.778 (4...

LIGHT-SCATTERING STUDIES ON SOLUTIONS OF CELLULOSE IN N,N-DIMETHYLACETAMIDE i LITHIUM CHLORIDE

These studies are based on the solvent System N,N-dimethylacetamide (DMAc)/LiCl which is used, e. g., for the determination of the molecular weight distribution of cellulosic Substrates by size exclusion chromatography (SEC).. Results are presented on static and dynamic laser-light-stattering experiments carried out in the concentration range employed in SEC and discussed in terms of the soluti...
