Process for the preparation of 2-vinyl-1,3-dioxolane |
| abstract |
Prepn. of 2-vinyl-1,3-dioxolane, comprises the following steps: (1) reaction of acrolein with ethylene glycol at less than 50 degrees C in the presence of a solid acid catalyst; (2) extraction of the reaction mixt. with an organic solvent having a b.pt. greater than 130 degrees C, in which ethylene glycol is essentially insoluble; and (3) distilln. of the aq. phase contg. ethylene glycol and the organic phase contg. the dioxolane. |
