Synthesis of Biobased and Substituted Terephthalic Acids and Isophthalic Acids

 

Executive Summary

 

Market and societal pressures are encouraging widespread utilization of biobased plastics. Many chemicals needed to make plastics, particularly PET, are derived from petroleum. This technology allows for the production of these necessary chemicals from either natural gas or renewable feedstocks.   

 

Description of Technology

 

This technology provides a route for the synthesis of terephthalic acid and isophthalic acid, both components of poly(ethylene terephthalate) (PET) plastics, from shell gas derived or renewable feedstocks. Newly developed shell gas derived- or biobased- acrylic acid and isoprene react to produce terephthalic acid and isophthalic acid. When these products are combined with biobased ethylene glycol, the process enables the manufacture of up to 100% renewable PET plastics, and also provides performance enhancing additives in polymer applications, while lowering dependence on petroleum. 

 

Key Benefits

  • Natural gas or renewable feedstocks
  • Plastics from 100% renewable sources
  • Enables access to inexpensive or renewable sources of conventional performance-enhancing additives

 

Applications

  • Biobased packaging
  • Plastic performance enhancing chemicals
