1,3-Propanediamine → HCID 131717714, compound

Participants

Reaction Steps

1,3-Diaminopropane (DAP) and liquid pivalic acid (PA) were preheated to 290° C. and fed to a vertical tubular reactor (R1; 1.5 inch diameter, 48 inch length) filled with 800 milliliters (ml) of alumina catalyst (grain size: 1-4 mm diameter). The reactor was kept at 290° C. The PA feed rate was 160 g/hour (hr), the DAP feed rate was 132 g/hr. This gave a DAP/PA molar ratio of 1.14. A mixture of 300 ml/minute (min) hydrogen and 150 ml/min nitrogen was used as the sweeping gas.
