摘要:

Nitrilotriacetic acid (NTA), a proposed detergent additive, and the related iminodiacetic acid (IDA) underwent rose bengalsensitized photooxidation. Formaldehyde, glycine, and IDA were products of NTA photooxidation: glycine and formaldehyde, of IDA photooxidation. The rates were slow. A reaction mechanism involving rearrangement of a quaternary N‐O species and subsequent concerted loss of CO2and formaldehyde is proposed.
