What is NMO Ochem?
N-Methylmorpholine-N-Oxide (NMO) is available commercially as the monohydrate; it has a melting point of 70 °C, and is stable under normal conditions. Because of this, NMO is a preferred stoichiometric oxidant for transition metal-catalyzed oxidations.
Is N methylmorpholine N oxide toxic?
Harmful by inhalation and if swallowed. Irritating to eyes, respiratory system and skin.
Is Nmmo toxic?
The NMMO cellulose solution, containing dispersed kaolinite, was applied in research conducted by Se Young Yoon (2007). Such a system was used to form paper-based composite materials of improved strength properties. The method applied in this research is safe because the solvent is both non-toxic and non-flammable.
What is the pKa of morpholine?
about 8
What is the pKa of pyridine?

What does oso4 and NMO do?
NMO is also the cooxidant that enables the use of a catalytic amount of OsO4, because this reagent is able to reoxidize an Os(VI) species to an Os(VIII) species: The mechanism is simplified, for example in alkaline solutions, the catalyst is indeed hydrated. The key step is the cycloaddition of OsO4 to the olefin.
What is oso4 selective for?
OsO4 For The Formation Of Vicinal Diols From Alkenes Osmium tetroxide (OsO4) is a volatile liquid that is most useful for the synthesis of 1,2 diols from alkenes. The reaction is very mild, and usefully leads to the formation of syn diols.
What is the lyocell process?
Lyocell is made by dissolving wood pulp in amine oxide solution. The viscous cellulose solution that results is then extruded into a dilute solution of amine oxide, which precipitates the cellulose as fibre.
Is morpholine an amine?
Morpholine is an organic chemical compound having the chemical formula O(CH2CH2)2NH. This heterocycle features both amine and ether functional groups. Because of the amine, morpholine is a base; its conjugate acid is called morpholinium.
