Zusammenfassung:	The present invention relates to a process for producing cyclic acetal comprising i) preparing a liquid reaction mixture comprising a) a formaldehyde source, b) an aprotic compound and c) a catalyst; wherein the total amount of protic compounds is less than 40 wt.-%, based on the total weight of the reaction mixture; and ii) converting the formaldehyde source into cyclic acetals. La présente invention concerne un procédé de production d'acétal cyclique consistant i) à préparer un mélange réactionnel liquide comprenant a) une source de formaldéhyde, b) un composé aprotique et c) un catalyseur ; la quantité totale de composés protiques étant inférieure à 40 % en poids, sur la base du poids total du mélange réactionnel ; et ii) à convertir la source de formaldéhyde en acétals cycliques.
