Mixing methanol and water
WebThe invention relates to a process for the epoxidation of an olefin comprising (a) reacting the olefin with hydrogen peroxide in the presence of methanol as solvent in at least two reaction stages to obtain a mixture (M-a) comprising olefin oxide, unreacted olefin, methanol and water, wherein between at least two reaction stages, olefin oxide is separated by … Web13 aug. 2024 · When methanol is mixed with water, a miscible mixture (solution) is formed. What is going on during this process? Both water (H2O) and methanol (CH3OH) exhibit hydrogen bonding between like molecules. So, both liquids are held together by H-bonding. Now, when mixed, several things happen.
