<p>The invention relates to a method for the continuous production of a 1,3-dioxolane-2-one of formula (I) where R1 represents hydrogen or an organic radical comprising 1 to 40 carbon atoms and R2 and R3, which can also be bonded to one another to form a five-membered or six-membered ring, independently represent hydrogen or C1-C4 alkyl. In said method, a product from the reaction zone is separated by means of a semipermeable membrane in order to separate secondary polymer products.</p> |
