Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The composition containing 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene (HCFO-1437dycc) produced by existing methods includes impurities and by-products that can cause reliability and performance issues when used as cleaning agents, solvents, refrigerants, or aerosols, necessitating a method to reduce their content.
Innovation Solution
A method involving bringing a composition containing HCFO-1437dycc into contact with a solid adsorbent, such as activated carbon, zeolite, silica, or alumina, to remove impurities like water, 3,3,4,4,5-hexafluoro-1-pentyne, and oxides, thereby reducing their content and enhancing the purity of HCFO-1437dycc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing production methods are used to produce HCFO-1437dycc, then the production process is simple and fast, but the composition contains impurities and by-products that cause reliability and performance issues
Solution Approach 1:
The production process is divided into two distinct stages: (1) rapid production of HCFO-1437dycc using existing methods, and (2) purification of the composition using solid adsorbents. This segmentation allows the simple and fast production method to be maintained while adding a separate purification step to remove impurities and by-products, thereby resolving the contradiction between production simplicity and product reliability.
Solution Approach 2:
Solid adsorbents are used to extract and remove impurities and by-products from the HCFO-1437dycc composition. The adsorbents selectively adsorb harmful substances such as unreacted starting materials, side reaction products, and decomposition products, separating them from the desired product. This extraction process improves reliability and performance while maintaining the integrity of the main production method.
2Reliability
If purification steps are added to remove impurities, then reliability and performance improve, but the production process becomes more complex and time-consuming
Solution Approach 1:
Instead of implementing extensive purification throughout the entire production process, the invention applies purification locally at the final stage using solid adsorbents. This targeted approach removes impurities efficiently without requiring multiple sequential purification steps, thereby maintaining high productivity while achieving the desired reliability and performance improvements.
Solution Approach 2:
The invention uses solid adsorbents that can be easily separated from the composition after purification. These adsorbents act as disposable purification agents that are discarded after use, eliminating the need for complex regeneration or recovery systems. This approach simplifies the overall process and maintains high productivity while ensuring thorough purification for improved reliability.
