Definitions

• the present invention generally relates to deuterium-enriched aldehydes, compositions comprising deuterium-enriched aldehydes, and methods for slowing the rate of aldehyde autoxidation.
• Aldehydes are organic compounds containing a H-C(O)- moiety. They are used extensively in industrial processes. Formaldehyde, for instance, is produced on a scale of about 6,000,000 tons/year. Aldehydes are mainly used in the production of resins, but they also find application as precursors to plasticizers and other compounds used in the manufacturing of polymers. On a smaller scale, some aldehydes are used as ingredients in perfumes, flavors and compositions that modulate the behavior of insects, e.g., pheromone containing compositions.
• Aldehydes have a tendency to react with atmospheric oxygen to form carboxylic acids (H-C(O)- oxidizes to H0 2 C-) in a process known as auto-oxidation or autoxidation.
