BIS(2-METHOXYETHOXY)METHANE synthesis
- Product Name:BIS(2-METHOXYETHOXY)METHANE
- CAS Number:4431-83-8
- Molecular formula:C7H16O4
- Molecular Weight:164.2
Yield: 94.4%
Reaction Conditions:
with Amberlyst15 catalyst in water;tolueneReflux;Reagent/catalyst;Solvent;
Steps:
1-8 Example Two
In a 1000 mL three-neck reaction flask, 30 g of paraformaldehyde, 193.2 g of 2-methoxyethanol, and 25 g of Amberlyst15 catalyst were added. 500 mL of toluene with water was added, and a water separator was added. The temperature was raised until toluene refluxed with water until no more water was formed. Reduce the temperature to room temperature, filter off the catalyst, evaporate toluene, and add 5 g of potassium carbonate to neutralize the catalyst, filter off potassium carbonate and otherSalt, add 75 mL × 2 double distilled water, and collect the oil phase after layering. The oil phase was dried with anhydrous magnesium sulfate, and then distilled under reduced pressure. A 100-101C fraction at a pressure of 24 mm Hg was collected to obtain 155 g of a product with a yield of 94.4%.
