Process for the production of ethers starting from alcohols, in the presence of liquid acid catalysts, comprising the following steps: a) sending a stream containing C 4 -C 10 alcohols to a reaction zone obtaining a product consisting of ethers and the acid catalyst; b) feeding the product consisting of ethers and the acid catalyst to an extraction zone with C 4 -C 10 alcohols in order to obtain a stream consisting of ethers and a stream containing said alcohols and said catalyst; c) sending the non-reacted alcohols and the water formed by the reaction zone to a distillation zone from which an azeotropic alcohol/water stream is obtained together with the residual stream which is sent to the reaction zone; d) sending the azeotropic alcohol/water stream to a separation zone to separate the alcohol, which is recycled to the reaction zone, from the aqueous stream. |
