Interpretive Summary:

Technical Abstract: Isostearic acids are unique and important biobased products with superior properties. Unfortunately, they are not widely utilized in industry because they are produced as byproducts from a process called clay-catalyzed oligomerization of tall oil fatty acids. Generally, this clay method results in the formation of monomeric (10-40% isostearic acids and iso-oleic acids) and predominantly oligomeric (60-80% dimer and trimer) fatty acid fractions. There is a need to develop new technologies to produce isostearic acids efficiently and economically. This feature article provides a brief summary on the existing and new methodologies for isostearic acid production, with a particular focus on our breakthrough zeolite methods to produce isostearic acids with a more desirable yield (>80 wt%) and conversion (>95%).
