METHOD FOR THE PRODUCTION OF ACETALS |
摘要 |
A method for the production of acetals from aldehydes and alcohols carried out in the following manner; a reaction/distillation area, which is provided with an acidic fixed bed catalyst, is produced in a distillation column; the aldehyde and alcohol is supplied to the reaction/distillation area and reacted at least partially to form acetal; the bottom of the column, which is arranged below the reaction /distillation area, is heated in order to at least partially evaporate the bottom mixture and to set a defined temperature in the reaction/distillation area; an extraction agent is fed into an enriching section of the column, which is arranged above the reaction/distillation area and a product with more than 90 weight per cent acetal is condensed at the head of the column. |
