Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diols used in polymer synthesis are predominantly derived from petroleum, and there is limited attention given to diols with a furan skeleton derived from cellulosic biomass.
Innovation Solution
Development of novel diols derived from 5-hydroxymethyl furfural (HMF), diformyl furan (DFF), or their derivatives, along with the synthesis of diglycidyl ethers from these diols, which can be used in composites, adhesives, and curable coating compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petroleum-based diols are used for polymer synthesis, then current industrial production standards are met, but sustainability and depletion of fossil fuels become problematic
Solution Approach 1:
The invention changes the source material parameter from petroleum-based to bio-based feedstocks (HMF, DFF, FDCA). This substitution maintains the functional properties needed for polymer synthesis while improving sustainability and reducing dependence on depleting fossil fuel resources
Solution Approach 2:
The invention uses readily available, inexpensive bio-based feedstocks (HMF, DFF, FDCA) that can be produced from renewable biomass sources. These short-living, renewable materials replace long-lived fossil fuel resources, providing a sustainable alternative that aligns with circular economy principles
2Reliability
If diols with furan skeleton from cellulosic biomass are used, then sustainability is improved, but limited attention and lack of established methods exist
Solution Approach 1:
The invention performs preliminary actions by establishing complete synthesis pathways from bio-based feedstocks (HMF, DFF, FDCA) to diol monomers and their glycidyl ether derivatives. These pre-developed methodologies provide ready-to-use routes for manufacturing sustainable polymer materials, eliminating the need for separate method development
Solution Approach 2:
The invention segments the synthesis process into distinct, manageable steps: (1) obtaining diols from HMF/DFF/FDCA through specific chemical transformations, (2) synthesizing glycidyl ether derivatives from these diols, and (3) applying them in polymer synthesis. This segmentation makes the complex bio-based manufacturing process easier to implement and scale
