N-n-propylacrylamide (NNPAM) was synthesized by a Schotten-Baumann reaction following the protocol described by Hirano et al.50 (link). A solution of 0.5 mol of acryloyl chloride (Alfa Aesar, Ward Hill, U.S.A) in 200 ml dichloromethane (HiPerSolv, VWR, Center Valley, U.S.A.) was added dropwise over 3 hours to a mechanically stirred and ice-bath cooled solution of 0.6 mol of n-propylamine (purum, Sigma-Aldrich, St-Louis, U.S.A.) and 0.5 mol of triethylamine (for synthesis, Carl Roth GmbH & Co. KG, Karlsruhe, Germany) in 200 ml dichloromethane. The mixture was kept stirring at room temperature for 24 hours and filtrated with a Büchner funnel afterwards. The filtrate was washed with 10% sodium hydrogen carbonate and dried over sodium sulfate. The solvent was removed by rotary evaporation and the final product obtained after vacuum distillation (115 °C, 10 mbar) with a yield of 30–40%.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
