Abstract:
Ketones, specifically Methyl ethyl ketone (“MEK”) and octanedione, may be formed from six carbon sugars. This process involves obtaining a quantity of a six carbon sugar and then reacting the sugar to form levulinic acid and formic acid. The levulinic acid and formic acid are then converted to an alkali metal levulinate and an alkali metal formate (such as, for example, sodium levulinate and sodium formate.) The alkali metal levulinate is placed in an anolyte along with hydrogen gas that is used in an electrolytic cell. The alkali metal levulinate within the anolyte is decarboxylated to form MEK radicals, wherein the MEK radicals react with hydrogen gas to form MEK, or MEK radicals react with each other to form octanedione. The alkali metal formate may also be decarboxylated in the cell, thereby forming hydrogen radicals that react with the MEK radicals to form MEK.
