Microwave spectrum of morpholine [PDF]

Canadian Journal of Chemistry, 1969
The microwave spectra of morpholine and N-deuteromorpholine have been investigated within the 8 to 40 GHz region. For both the normal and the deuterated species, strong a-type spectra which are due to the chair conformer with an equatorial imino group were recorded.

Aminomethylation of Imidazoheterocycles with Morpholine

Organic Letters, 2017
A hitherto unreported aminomethylation occurs at C-3 of imidazopyridines with morpholine in the presence of (diacetoxyiodo)benzene at ambient temperature in short reaction times. This methodology is also applicable to indolizine, imidazo[2,1-b]thiazole, benzo[d]imidazo[2,1-b]thiazole, and indole. Interestingly, the aminomethylation involving morpholine

Morpholine Biodegradation in a Bioreactor

Journal of Chemical Technology & Biotechnology, 1996
The degradation of morpholine, often reported as a recalcitrant compound, by a mixed culture consisting of nine bacteria and two yeasts in a bioreactor is described. The fermentation process was first carried out in discontinuous culture using different initial morpholine concentrations.

Morpholine-2,5-dione

Acta Crystallographica Section C Crystal Structure Communications, 2006
In the title compound, C4H5NO3, the morpholine ring adopts a boat conformation that is distorted towards twist-boat, the boat ends being the two Csp3 atoms of the ring. The molecular packing is stabilized by the establishment of strong intermolecular NH...OC hydrogen bonds, which give rise to centrosymmetric dimers, and a network of weak CH2...OC ...

Distribution and disposition of morpholine in the rabbit

Toxicology, 1981
The results of a variety of in vivo and in vitro experiments suggested that the kidneys were the primary route of elimination of morpholine in the rabbit. Morpholine was not bound to serum proteins and was excreted 90% unchanged. The concentration of [14C]morpholine in the renal cortex was 6.6 times the concentration in the blood, and in the renal ...

The microbial degradation of morpholine

Journal of Applied Bacteriology, 1982
Morpholine can be completely degraded microbiologically, and two organisms have been isolated, each capable of growth in a simple mineral salts medium with morpholine as the sole source of carbon, nitrogen and energy. Excess nitrogen is liberated as ammonia.

New Morpholine Derivatives

Chemistry of Heterocyclic Compounds, 2005
A study was carried out on the reaction of morpholine with 2,5-di(chloromethyl)-p-xylene, 4,6-di(chloromethyl)-m-xylene, 4,5-di(chloromethyl)-o-xylene, 4,4′-bis(chloromethyl)diphenyl, 4,4′-bis-(chloromethyl)diphenyl ketone, and 4,4′-bis(chloromethyl)diphenyl sulfide.

LSER in the allylation of morpholine

Reaction Kinetics and Catalysis Letters, 2009
The second order rate constants of allylation of morpholine are obtained conductometrically in different protic and aprotic solvents in the temperature range 303–318K. Correlation of the rate data with different solvent parameters indicates that, the reaction rate is simultaneously influenced by the hydrogen bond donor ability (α), nucelophilicity (B ...

4-(2,4-Dinitrophenylsulfanyl)morpholine

Acta Crystallographica Section C Crystal Structure Communications, 2006
In the title compound, C10H11N3O5S, the 2,4-dinitro­phenyl fragment is connected by an S atom to the morpholine ring, which is in a chair conformation. The ortho- and para-nitro groups are slightly twisted out of the plane of the benzene ring. The mol­ecules are linked into C(7) and C(10) chains by two inter­molecular C—H⋯O hydrogen bonds.
