Study of trioxane production process with super- or subcritical fluid as solvent and extractant

Article abstract of DOI:10.1080/00397910600631908

A super- or subcritical fluid was used as a reaction solvent for nonaqueous trioxane synthesis instead of common organic solvents. The generation of trioxane from paraformaldehyde was observed in the presence of the catalyst when carbon dioxide reached a supercritical region, suggesting that the supercritical carbon dioxide acted as the reaction solvent. In the case of Freon 12, the trioxane was effectively produced even in a subcritical state. Copyright Taylor & Francis Group, LLC.
