Japanese Patent JPS5318514
Kind Code:
B2
Abstract:
1,3,6-TRIOXOCANE IS PREPARED IN A HIGH YIELD BY THE PROCESS WHEREIN AN OLIGOMER CONSISTING OF CONDENSED FORMALDEHYDE AND DIETHYLENE GLYCOL IS PREPARED IN THE PRESENCE OF A CATALYTIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF INORGANIC ACIDS, ACID SALTS OF INORGANIC ACIDS, ALKALI METAL SALTS OF PERSULFURIC ACID AND ORGANIC SULFONIC ACIDS BY REACTING DIETHYLENE GLYCOL WITH A SUBSTANCE CAPABLE OF RELEASING FORMALDEHYDE THEREFROM UNDER THE REACTION CONDITION, THE RESULTING OLIGOMER IS CYCLIZED TO 1,3,6-TRIOXOCANE BY HEATING IT AT A TEMPERATURE OF 150 DEG TO 250 DEG C under a normal or reduced pressure in the presence of a catalytic compound selected from the group consisting of alkali metal salts of persulfuric acids, ferrous sulfate and ferric sulfate and, then, the resulting 1,3,6-trioxocane is isolated by way of distillation.
