Here we show effect of the polyamine polymer chain length to BET isotherms. According to IUPAC classification [1], all three polymers are fitting type 1 physical adsorption isotherm with H3 hysteresis (except for EDA having H2 hysteresis). Moreover, TG and TGA analysis of polymers triazine-ethylenediamine (EDA) and triazine-triethylenetetramine (TETA) are provided. Due to the similarities of th...

A novel flame retardant, Triethylenetetramine phosphonate ammonium (TECHPA), containing and phosphate groups, was synthesized characterized by 1H, 13C, 31P nuclear magnetic resonance (NMR) spectroscopy. The results showed that the Limiting oxygen index (LOI) of cotton fabric treated with 40 g/L TECHPA reached 36.8%, which remained at 31.1% after 50 laundering cycles. infrared spectra durability...

Carbon sequestration via the carbon capture and storage (CCS) method is one of most useful methods lowering CO2 emissions in atmosphere. Ethylenediamine (EDA)- triethylenetetramine (TETA)-modified mesoporous (MC) has been successfully prepared as a material. The effect various concentrations EDA or TETA added to MC, well activated (AC), on their adsorption capacity were investigated using high-...
