Acetal purification with superoxides |
| abstract |
Trioxane and other acetals are purified by contacting with an alkali metal superoxide, then isolated in a purified form. Optionally, a phase transfer catalyst can be utilized in the purification. Recovered acetals are sufficiently pure for polymerization to high molecular weight. |
