use | organic synthesis intermediate. |
production method | dimethyl sulfate is added dropwise to hydroxyacetonitrile solution, the reaction is exothermic, and the drop acceleration is controlled to maintain the temperature at 12-15 ℃. After dropping, continue to cool and stir for 40min. The oil layer is separated by standing and fractionated to obtain methoxyacetonitrile. |
