Solution Overview
Problem
Existing methods for preparing 5-acetoxymethyl furfural (AMF) from sugar ingredients require separation and purification steps to remove extraction solvents, making the process costly and inefficient.
Innovation Solution
A method involving a two-phase solvent system with an aqueous phase and an organic phase using an organic extraction solvent with a relative polarity of 0.2 or less, where a sugar ingredient is converted to 5-halomethyl furfural (XMF) in the aqueous phase and then extracted into the organic phase, followed by the addition of acetate ions to convert XMF into AMF directly in the organic phase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separation and purification steps are performed to remove extraction solvent, then product purity is improved, but process complexity and cost increase
Solution Approach 1:
The patent combines the extraction and reaction steps into a single integrated process. The organic phase containing XMF is directly used as the reaction medium without separation and purification, merging the extraction function with the reaction function, thereby eliminating the need for separate separation equipment and reducing process complexity
Solution Approach 2:
The patent extracts XMF into the organic phase and utilizes this extracted XMF directly in the subsequent reaction step. By taking out XMF from the aqueous phase into the organic phase and using it directly, the patent eliminates the need for separation and purification steps while maintaining product purity
2Manufacturing precision
If separation and purification equipment is used, then product quality is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the extraction and reaction steps into one process, eliminating the need for separate separation and purification equipment. This integration directly reduces manufacturing costs by removing the need for additional equipment and operational steps while maintaining product quality through controlled extraction conditions
3Manufacturing precision
If traditional multi-step process is used, then product purity is ensured, but productivity decreases
Solution Approach 1:
The patent implements continuous useful action by directly using the extracted XMF in the organic phase for the reaction without interruption for separation and purification. This continuous process eliminates idle time between steps, maintains reactant concentration, and significantly improves productivity while ensuring product purity through controlled extraction
Solution Approach 2:
By combining extraction and reaction into a single continuous operation, the patent eliminates the time loss associated with multiple separation steps, thereby improving overall process efficiency and productivity while maintaining product quality
