3 C. Total Nitrosamine Analysis A schematic for total nitrosamine analysis is shown below. The data from the NO x analyzer shows clear reproducible peaks that are linear with nitrosamine concentration. The response is equivalent across multiple nitrosamines tested.

Total Aldehyde Analysis A new method was developed for detecting aldehydes and ketones in degraded amine solvents by reaction with 2,4-dintrophenylhydrazine (DNPH) followed by analysis using HPLC. The preparation method was: 1. In a glass HPLC vial, the concentrated amine sample was diluted by a factor of 50X to 500X in 1 ml of 2:1 vol:vol methanol and 10 mm ammonium carbonate buffer. The dilution factor must be sufficient to reduce the total aldehyde content of the sample to less than 3 mmol/kg, the concentration of DNPH that was added to the samples.

5 ml of 0.4 wt % DNPH diluted in acetonitrile was then added. The solution was then capped, stirred, and allowed to react at room temperature for 24 hours. 3. The reacted solution was then injected directly on HPLC using an Acclaim Polar Advantage II C18 5 μm 120 Å 4.6 x 150 mm reverse phase column with UV detection at 365 nm, using the eluent ramp shown in Figure 12. DNPH reacts rapidly with aldehydes and slowly with amines. To account for this, a fresh amine sample was prepared and run at the same dilution as the degraded solvent samples. The difference between the expected and observed DNPH peak at 9.1 minutes was used to calculate the total aldehyde concentration of the sample. A 50 mmol/kg sample of MNPZ was prepared in 7.5 M PZ and thermally degraded at 175 C. This was then reacted with DNPH. The reaction mixture was run on HPLC repeatedly for 20 hours after the DNPH was added. Figure 13 shows the initial chromatogram and the chromatogram 20 hours later. The first peak in the chromatogram at 2.5 minutes is postulated to be the DNPH-amine derivative peak. It appears in all DNPH-reacted amine samples and accumulates steadily, as shown in Figure 14. The peak at 3.2 minutes appears only in degraded PZ and MNPZ samples, not in fresh amine samples. Direct injection mass spectroscopy on the degraded MNPZ sample determined that the major product of MNPZ decomposition is 2-piperazinol (2-PZOH), a hemiaminal (Figure 16). This hemiaminal will be in equilibrium with N-(2-ethanal)-ethylenediamine, an aldehyde, as shown in Figure 15. It is postulated that the peak at 3.2 minutes is the DNPH derivative of this product. The peak is fully formed within 12 hours of mixing with DNPH. A prediction of DNPH peak disappearance over time based on the areas of the 2.5 minute and 3.2 minute peaks was compared to the observed DNPH peak. This shows that the DNPH is not reacting with any other unknown products in the thermally degraded MNPZ sample. A regression of the peak area data determined that the 2-PZOH peak followed a calibration curve of mmol/kg/(mau*min).
