Production of polyesters from bio-based feedstocks

Description:

Project ID:  D2014-20

Background
Polyesters are often used to make fabric for clothing and other household items. Manufacturers of polyesters typically use non-renewable fossil fuels as the feedstock, resulting in an emission intensive and environmentally harmful process. On the other hand, furfural is a platform chemical and bio-based feedstock derived from lignocellulose sources, such as corn husks or oat hulls. It can be used to make a range of furan-based chemicals. It would be ideal to utilize bio-based feedstocks, such as fufural, to produce polyesters. 

Invention Description
Researchers at the University of Toledo have developed a method to synthesize bis-furan diol (BFD) and bis furan diamide (BFA) from bio-based feedstocks. BFD and BFA can be further processed to synthesize bisfuran-based polymers, such as polyesters, polyamides, polyethers, polycarbonates, and polyurethanes. For example, researchers have demonstrated synthesis of bis furan polyester (BFPE) with a molecular weight of 5kDa using this technique.

Applications

  • Synthesis of bis-furan
  • Synthesis of bis-furan diol (BFD) and bisfuran diamide (BFA) from furfural
  • Synthesis of a bis-furan polyester

Advantages

  • Uses bio-based feedstock
  • Higher renewable content
  • Only four steps are required to achieve BFD and BFA
