Title: Innovations of David Paul Anderson
Introduction
David Paul Anderson is a notable inventor based in Amherst, Massachusetts. He has made significant contributions to the field of chemical engineering, particularly in the recovery of chemical components from cellulosic regenerating solutions. With a total of two patents to his name, Anderson's work demonstrates a commitment to advancing sustainable chemical processes.
Latest Patents
Anderson's latest patents focus on the recovery of chemical components from cellulosic organic solvent regenerating solutions. The first patent outlines a process that involves distilling a solution containing a dialkylacylamide, a lower aliphatic monohydric alcohol, a nitrite of the alcohol, and nitric acid. This innovative process allows for the removal of the alcohol nitrite and alcohol, leading to the recovery of the dialkylacylamide and nitric acid. The process also includes hydrolyzing the alcohol nitrite to convert it back to alcohol and nitrous acid, followed by neutralization and distillation to recover remaining chemicals. The result is a substantial recovery of process chemicals, showcasing Anderson's ingenuity.
The second patent similarly addresses the recovery of chemical components from a cellulosic regenerating solution. This process involves neutralizing the solution to form metal salts of nitrous and nitric acid, followed by distillation to recover water and dialkylacylamide solvent. The metal salts are then pyrolyzed in the presence of oxygen to recover nitrogen dioxide gas. This method also results in a significant recovery of process chemicals, further emphasizing Anderson's contributions to sustainable chemical practices.
