Chemical Properties
White to pale yellow powder
Uses
In UV-curable color paints, N-Nitroso-N-phenylhydroxylamine aluminum salt is the preferred polymerization inhibitor. It can accept small amounts of free radicals generated by free radical photoinitiators due to heat, light or other reasons, thus preventing the tendency to initiate monomer polymerization and gelation.

Synthesis
In the solvent mixture of alcohol and water, the pH of the reaction solution was controlled at in 5.5~5.7, and the reaction of aluminum nitrate with N-nitroso-N-phenylhydroxylamine ammonium salt, the yield of N-Nitroso-N-phenylhydroxylamine aluminum salt reached more than 91%.
