In the future, the clothes you wear could be made from sugar. Researchers at the Institute of Bioengineering and Nanotechnology (IBN) have discovered a new chemical process that can convert adipic acid directly from sugar. Adipic acid is an important chemical used to produce nylon for apparel and other everyday products like carpets, ropes and toothbrush bristles. Commercially, adipic acid is produced from petroleum-based chemicals through the nitric acid oxidation process, which emits large amounts of nitrous oxides, a major greenhouse gas that causes global warming. IBN Executive Director Professor Jackie Y. Ying said, “In the face of growing environmental concerns over the use of fossil fuels and diminishing natural resources, there is an increasing need for a renewable source for energy and chemicals. We have designed a sustainable and environmentally friendly solution to convert sugar into adipic acid via our patented catalytic process technology.” Bio-based adipic acid can be synthesized from mucic acid, which is oxidized from sugar; and the mucic acid can be obtained from fruit peels. Current processes are either performed using multiple steps with low product efficiency and yield, or under harsh reaction conditions using high-pressure hydrogen gas and strong acids, which are costly and unsafe.
