such systems. The volatility of DEHA increases from 100 psig to 300 psig and then falls gradually at increasing pressures. DEHA, therefore, behaves in a similar manner as neutralizing amines. It would, therefore, be expected that volatility at high pressure will still be for giving residuals in steam.
