Abstract
We describe the direct syntheses of N,N–diethylcarbamic acid (DECA) and of N,N-dibutylcarbamic acid (DBCA), from CO2 and the corresponding secondary amines. After isolation in crystalline form (no previous reports were found on separated and pure DECA and DBCA), the obtained dialkylcarbamic acids were characterized by spectral methods (FT- IR and NMR). Formation and decomposition reactions of these carbamic acids may play potential role in the 13CO2 – 12CO2 isotopic enrichment and by this, in decreasing the greenhouse effect of the flue gases via absorbing CO2 in secondary amines applying mild, green technologies.Keywords
