WebThe synthesis of stearamide (stirring) Stearic acid (28.488 g added) is a white solid with a melting point between 67 °C and 72 °C. It needed to be melted before the reaction. Diethylenetriamine (6 mL) was added dropwise into the liquefied stearic acid in a flask while the temperature was held constant at 72 °C. WebThe synthesis involved 2-step processes of functionalization of cardanol by maleic anhydride followed by its condensation with diethylenetriamine (DETA) in the 2nd step. The polyamides with different molecular weights were prepared by varying the mole ratios of acid and amine components in the formulation.
