摘要 |
Process for the production of ethers starting from alcohols, in the presence of liquid acid catalysts, essentially comprising the following steps:a) sending a stream containing C4-C10 alcohols to a reaction zone obtaining a product essentially consisting of ethers and the acid catalyst;b) feeding the product essentially consisting of ethers and the acid catalyst to an extraction zone with C4-C10 alcohols in order to obtain a stream essentially 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. |
