4-Methylmorpholine N-oxide synthesis

4synthesis methods
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.

EXAMPLES

Execution of the Reaction in the Microreactor
The microreaction system used by us is based on WO 2010/055034 and was produced from the material [A] according to the table.
The microreactor tests for the synthesis of N-methylmorpholine N-oxide (NMMNO) from 4-N-methylmorpholine (NMM) and hydrogen peroxide (H2O2) were carried out in different fittings in the microreactor.
The characteristic data of the used reactor (1) are as follows:
volume: variable, up to 26 mL
