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.
Allgemeine Beschreibung
4-Methylmorpholine?
N-oxide is an organic compound used as a co-oxidant along with OsO
4 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.
Synthese
A preparation method of N-methylmorpholine-N-oxide comprises the following steps: (1) adding the nano metal oxide into N-methyl morpholine (NMM) and mixing and stirring to uniformly mix the nano metal oxide with the NMM; (2) dropwise adding a hydrogen peroxide solution into a mixed solution of NMM and a catalyst; (3) raising the temperature to accelerate the reaction process; (4) and (4) filtering and distilling the solution prepared in the step (3) under reduced pressure to obtain the required NMMO solution. The method for preparing NMMO provided by the present disclosure has the advantages of a fast reaction rate, low reaction temperature, few byproducts, etc.
l?uterung 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.
