応用分野
用途有機合成原料。
用途N-メチルモルホリン N-オキシド (N-methylmorpholine N-oxide) は、有機化合物の一種で、有機合成において酸化剤として用いられる試薬。
使用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.
一般的な説明4-MethylmorpholineN-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-methylmorpholineN-oxide in an eco-friendly manner.
調製方法
純化方法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.
