| titleOfInvention | METHOD FOR PROCESSING ALDEHYDE MIXTURE, APPLICATION OF PROCESSED ALDEHYDE AND ALCOHOL |
| abstract | 1. A method of treating an aldehyde mixture containing a carboxylic acid and a metal cation, where the method includes! contacting the aldehyde mixture with an alkaline separation medium to separate at least a portion of the carboxylic acid from the mixture, and! subsequent or simultaneous contact with an acidic separation medium to separate at least a portion of the metal cations from the mixture. ! 2. The method of claim 1, wherein the method further comprises controlling the pH of the aldehyde mixture to at most 6, as measured at operating temperature, while in contact with the alkaline separation medium. ! 3. A method according to claim 1 or 2, wherein the pH of the aldehyde mixture is kept at a pH of at most 5.5 when measured at the operating temperature, in particular at a pH of at most 5 when measured at the operating temperature. ! 4. A method according to claim 1 or 2, wherein the alkaline separation medium comprises an alkaline anion exchange resin. ! 5. The method of claim 4, wherein the alkaline anion exchange resin comprises a weakly alkaline anion exchange resin. ! 6. The method of claim 1 or 2, wherein the alkaline separation medium comprises a metal oxide. ! 7. The method of claim 6, wherein the metal oxide comprises one or more of activated alumina, titanium dioxide, zirconia, chromium dioxide, and mixtures thereof, in particular activated alumina. ! 8. A method according to claim 1 or 2, wherein the aldehyde mixture is contacted with an alkaline separation medium at a temperature of 5 to 45 ° C and at an hourly space velocity of 1 to 10 volumes of liquid per volume of alkaline separation medium per hour. ! 9. A method according to claim 1 or 2, wherein the carboxylic acid contains 2 to 8 carbon atoms, in particular 2 to 4.! 10. The method according to claim 1 or 2, wherein the carboxylic acid |
