    摘要: A process for the preparation of an ether compound is disclose, wherein the ether compound is prepared via a reaction from at least an alcohol (I) and an alcohol (II), optionally using a catalyst X, wherein alcohol (I) and alcohol (II) are forming a biphasic liquid system when mixed together; comprising at least the following steps: a) Producing an alcohol (I)/alcohol (II) emulsion by using as stabilizing species amphiphilic solid particles of nanometric dimension; optionally comprising a catalyst X; b) Proceeding to the reaction of the ether compound by setting temperature, and c) Isolating the ether compound.
