The Influence of Phosphate Buffer on the Formation of N-Nitrosodimethylamine from Dimethylamine Nitrosation

<table>NDMA formation in the presence of variable amounts of NaH<sub>2</sub>PO<sub>4</sub> and Na<sub>3</sub>(C<sub>6</sub>H<sub>5</sub>O<sub>7</sub>) addition; 4 h reaction; 90°C. The pH was maintained at 6.4 with Na<sub>3</sub>(C<sub>6</sub>H<sub>5</sub>O<sub>7</sub>)/C<sub>6</sub>H<sub>8</sub>O<sub>7</sub> buffer.
