发明名称 Process for the production of ethers from alcohols
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.
