摘要：Synthesis of hot melt adhesives from dicarboxylic fatty acid and ethylenediamine is presented for the undergraduate organic laboratory. The project fulfills the requirement of undergraduate chemistry and chemical engineering students. The experimental setup is utilized for the determination of polymerization reaction rate constants and reaction order. The apparatus also provides a safe method for observing polymer formation. In this experiment students prepare, react, and convert dicarboxylic fatty acid to hot melt adhesive. Students will find reaction order and specific reaction rate of stoichiometric proportions of ethylenediamine and dicarboxylic fatty acid to produce polyamide adhesives using batch reactor. The experiment will expose students to observe the steps of adhesive formation along with problems phasing polycondensation reactions due to foam formation.
