Disclosed are catalysts comprised of platinum and gold. The catalysts are generally useful for the selective oxidation of compositions comprised of a primary alcohol group and at least one secondary alcohol group wherein at least the primary alcohol group is converted to a carboxyl group. More particularly, the catalysts are supported catalysts including particles comprising gold and particles comprising platinum, wherein the molar ratio of platinum to gold is in the range of about 100:1 to about 1:4, the platinum is essentially present as Pt(0) and the platinum-containing particles are of a size in the range of about 2 to about 50 nm. Also disclosed are methods for the oxidative chemocatalytic conversion of carbohydrates to carboxylic acids or derivatives thereof. Additionally, methods are disclosed for the selective oxidation of glucose to glucaric acid or derivatives thereof using catalysts comprising platinum and gold. Further, methods are disclosed for the production of such catalysts.

Provided is a process for producing acrylic acid, the process including supplying a lactic acid raw material to an upper portion of a distillation tower; supplying water to a lower portion of the distillation tower; supplying a first lactic acid vapor vaporized in the distillation tower to a reactor; and supplying a second aqueous lactic acid solution not vaporized in the distillation tower to a middle portion of the distillation tower. The process uses a distillation tower instead of a vaporizer, and is capable of preventing formation of a lactic acid oligomer during vaporization of an aqueous lactic acid solution, and, by introducing a concentrated lactic acid raw material to the distillation tower as it is, is capable of producing acrylic acid without a separate dilution device.
