A Review of Guerbet Alcohols and Their Esters: Synthesis, Applications, and Future Perspectives

Guerbet alcohol esters are compounds with specific properties that make them particularly suitable for use as cosmetic ingredients, plasticizers, or biolubricants. Guerbet alcohols are used for their synthesis. These are primary alcohols with beta branching and a lower melting point than their linear counterparts. Due to the branching, the products are liquid at lower temperatures, have good volatility, and exhibit better color and oxidation stability. This paper presents a systematic literature review on the synthesis and applications of Guerbet alcohol esters. Finally, emphasis is placed on the future of these synthesis processes, which could be based on the use of biocatalysts, thus promoting the application of new environmentally friendly procedures.
