Cyclopropene Complex Water Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing cyclopropene complexes often result in the loss of cyclopropene due to water removal, leading to compositions with high water content and low cyclopropene levels.
Innovation Solution
A composition comprising cyclopropene complex with 2-10% water by weight and a mole ratio of cyclopropene to molecular encapsulating agent between 0.92:1 to 1.5:1, prepared by adding water, cyclopropene, and molecular encapsulating agent to a continuous reactor with controlled residence time, followed by water removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If water is removed from the cyclopropene complex solution, then the composition can be stored and handled as a powder, but cyclopropene is released and lost from the complex
Solution Approach 1:
The patent applies parameter changes by carefully controlling the water content to remain within 2-10% rather than completely removing it. This partial retention of water prevents cyclopropene release while still enabling powder form storage and handling, thus resolving the contradiction between ease of manufacture and substance loss.
2Stability of the object's composition
If water is completely removed to achieve low water content, then storage stability is improved, but cyclopropene levels decrease due to release during removal
Solution Approach 1:
The patent changes the water content parameter from complete removal to controlled retention at 2-10%. This optimization maintains storage stability while preserving cyclopropene levels by preventing the release that occurs during complete water removal.
3Quantity of substance
If standard water removal processes are used, then the composition can be concentrated, but cyclopropene diffuses into the atmosphere and decomposes
Solution Approach 1:
The patent applies parameter changes by controlling water content to 2-10% and optimizing the mole ratio of cyclopropene to molecular encapsulating agent. This approach enables concentration of the composition while minimizing cyclopropene diffusion and decomposition through the stabilized complex structure.
