| titleOfInvention | Process for the preparation of pure alkyl-tert.-alkyl ethers and hydrocarbonaceous raffinates freed for the major part from isoolefines and alkanols |
| abstract | Hydrocarbon mixtures containing at least one tertiary olefin are reacted with an alkanol on an acidic cation exchanger, resulting in a product mixture which contains the resulting alkyl tertiary alkyl ether, excess, unreacted alkanol and the remaining hydrocarbons which in the original hydrocarbon mixture were included. Furthermore, this product mixture contains minor amounts of unreacted tertiary olefin, which content can drop to 0 when the tertiary olefin is completely converted. The excess, unreacted alkanol is removed from the resulting product mixture or from a partial stream resulting from the workup by absorption on a synthetic ion exchanger with groups or mixtures exchanging cations or anions or mixtures of such ion exchangers as absorber resin. The alkanol to be introduced into the reaction zone is at least partially removed by desorption from an absorber resin loaded with this alkanol with the aid of the hydrocarbon mixture containing at least one tertiary olefin. For alkanol absorption and desorption, at least two absorber resin layers are used, which are switched from absorption to desorption and vice versa in cyclical operation. The product mixture leaving the etherification reactor can first be freed from excess alkanol on an absorber resin and then separated by distillation into the alkyl tert-alkyl ether and the residual gas. However, the product mixture leaving the etherification reactor can also first be separated by distillation into the alkyl tert-alkyl ether and into the residual gas, at least one of the partial streams obtained containing alkanol, and then the alkanol-containing partial stream (s) can be separated from the alkanol using an absorber resin . |
