Solution Overview
Problem
Fluoroethylene compositions face stability issues due to decomposition reactions and agglomerate formation, particularly when exposed to water and oxygen, which affect their performance in applications like heat transfer media and refrigerants.
Innovation Solution
A fluoroethylene composition containing 1,2-difluoroethylene with a water content of 100 mass ppm or less and an oxygen content of 0.35 mol % or less, which stabilizes the fluoroethylene by preventing adverse reactions and agglomerate formation, thereby maintaining its stability and performance over time.

Engineering Contradiction Analysis
1Reliability
If fluoroethylene is stored or used in conventional compositions, then it undergoes decomposition reactions and forms agglomerates, but controlling water and oxygen content to prevent decomposition requires stringent purity control measures
Solution Approach 1:
The patent specifies precise parameter ranges for water content (100 mass ppm or less) and oxygen content (0.35 mol % or less) to prevent decomposition reactions. By establishing these quantitative thresholds, the invention transforms the qualitative problem of stability into a controllable parameter optimization problem, where maintaining composition within these ranges ensures fluoroethylene stability without requiring overly complex control systems.
2Stability of the object's composition
If water and oxygen content are reduced to improve fluoroethylene stability, then decomposition and agglomerate formation are prevented, but the manufacturing and purification processes become more complex and costly
Solution Approach 1:
The patent establishes predetermined thresholds for water (100 mass ppm or less) and oxygen (0.35 mol % or less) content that should be achieved during the manufacturing process. By defining these target values in advance, the invention guides the purification process design and allows manufacturers to implement appropriate drying and degassing operations to reach these specifications, balancing purity requirements with manufacturing feasibility.
