| titleOfInvention | Process for obtaining substantially aldehyde-free ketone products |
| abstract | Tischtschenko condensation of aldehydes is used to nremove aldehydes from dry ketone-containing streams. nThe Tischtschenko condensation is used to condense the naldehydes into esters whose boiling points are nsignificantly different than the ketones, greatly nsimplifying the separation of the esters from the nketones. An organic extraction step is used to obtain a nsubstantially dry ketone containing stream. One nparticularly preferred class of extraction solvents is nselected from the group consisting of butane, pentane, nhexane, heptane, octane, nonane, decane and mixtures nthereof. In particularly preferred embodiments, the nTischtschenko reaction is used in the context of naqueous-phase catalyzed olefin oxidation to ketones. nThe aldehyde to ester condensation permits easy and nefficient removal of the aldehyde analogs of the desired nketones. |
