摘要:The present invention concerns a process for preparing cyclic acetal or ketal by reacting a carbonyl compound (a) with a polyol (b), wherein said carbonyl compound (a) and polyol (b) are forming a biphasic liquid system when mixed together, comprising at least the following steps: a) Producing a carbonyl compound (a) / polyol (b) emulsion by using as stabilizing species amphiphilic solid particles of nanometric dimension and optionally a catalyst X; b) Proceeding to the reaction to produce cyclic acetal or ketal, notably by setting temperature, and c) Isolating the resulting compounds.
