Verwenden
Non-metallic catalyst for the cyanosilylation of ketones. Co-oxidant for Sharpless asymmetric dihydroxylation in ionic liquids.
Verwenden
4-Methylmorpholine N-oxide acts as a non-metallic catalyst for the cyanosilylation of ketones. It is also employed as a co-oxidant for Sharpless asymmetric dihydroxylation in ionic liquids. It serves as a solvent in the Lyocell process to produce tencel fiber. Further, it is used in the preparation of aldehydes from primary alcohols in the presence of tetrapropylammonium perruthenate.
Verwenden
4-Methylmorpholine N-Oxide is a metabolite of Morpholine (M723725). N-Methylmorpholine N-Oxide is commonly used to dissolve cellulose as well as in the dissolution of of scleroproteins.
Definition
ChEBI: N-methylmorpholine N-oxide is a morpholine N-oxide resulting from the oxidation of the amino group of N-methylmorpholine.
Allgemeine Beschreibung
4-Methylmorpholine?N-oxide is an organic compound used as a co-oxidant along with OsO₄ and ruthenates in organic synthesis. In recent studies, it has been used as a catalyst in silylcyanation of aldehydes and ketones. Lyocell, a regenerated cellulose fiber, can be prepared using 4-methylmorpholine?N-oxide in an eco-friendly manner.
Flammability and Explosibility
Flammable
läuterung methode
When the oxide is dried for 2-3hours at high vacuum, it dehydrates. Add MeOH to the oxide and distil off the solvent under vacuum until the temperature is ca 95o. Then add Me2CO at reflux and cool to 20o. The crystals are filtered off, washed with Me2CO and dried. The degree of hydration may vary and may be important for the desired reactions.
