Method of Preparing Aminoundecane Acid and 11-Aminoundecanoic Acid or Structural Isomer Thereof by Hydroformylation Reaction

摘要

The present invention relates to a method for preparing 11-aminoundecanoic acid or its structural isomer using a hydroformylation reaction, and more particularly, an aminoundecanoic acid used as a monomer of a polyamide from an olefinic acid ester obtained through metathesis reaction of oleic acid. And its structural isomers can be prepared through hydroformylation, reductive amination, and hydrolysis reactions, and various polyamides having different physical properties depending on the ratio of each isomer, since the ratio of structural isomers can be adjusted according to the ligand. It is an eco-friendly way to manufacture.
