- Аннотация: In the present work N,N′-ethylenebisstearamide (EBS) in its free form and mixed with iron/carbon powder was thermolyzed in a closed system under vacuum to produce gas-phase products (GPP). A catalytic effect of the iron/carbon surface on the gasification of thermolyzed EBS is observed over the 573-973 K temperature range. The overall yield of GPP measured after one hour of heating at a constant temperature increased with temperature (T < 973 K) in both systems. The total yield, and the yields of the main identified GPP (CO, CH4, CO2 and C2H4), measured for free EBS are significantly lower (∼30 times) than those observed for mixture of EBS with iron/carbon powder. The catalytic formation of H2/N2, H2O and small amounts of other volatile11Compounds with a vapor pressure above 0.1 Torr at room temperature. organic products is assumed at temperatures below 973 K. The formation of GPP from low volatility products of EBS decomposition is assumed to proceed via at least two competing mechanisms (EBS → Primary products → 2CO (1) or CO2 (2)). This mechanistical model can be used as a basis for understanding the delubrication mechanism of ferrous compacts and for the catalytic gasification of heavy amides (EBS) or polyamides (Nylon) widely used in industry.
