METHOD OF PRODUCING HIGHER ALKANONES, PREFERABLY 6-UNDECANONE, AND DERIVATIVES THEREOF
A method of producing higher alkanones, preferably 6-undecanone, from ethanol and/or acetate, may include: (a) contacting the ethanol and/or acetate with at least one microorganism capable of carrying out carbon chain elongation to produce hexanoic acid and/or an ester thereof from the ethanol and/o...

| description | A method of producing higher alkanones, preferably 6-undecanone, from ethanol and/or acetate, may include: (a) contacting the ethanol and/or acetate with at least one microorganism capable of carrying out carbon chain elongation to produce hexanoic acid and/or an ester thereof from the ethanol and/or acetate; (b) extracting the hexanoic acid and/or ester thereof from the contacting (a) using at least one extractant in an aqueous medium, the extractant including at least one alkyl-phosphine oxide and at least one C12+ alkane; or at least one trialkylamine and at least one C12+ alkane; and (c) contacting the extracted hexanoic acid and/or ester thereof from (b) with at least one ketonization catalyst and eventually a further C1 to C22 alkanoic acid under suitable reaction conditions for chemical ketonization of hexanoic acid and eventually the further alkanoic acid to a higher alkanone, preferably 6-undecanone. |
