Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Azole silane compounds have limited solubility in typical solvents, leading to premature polymerization and contamination by halides during synthesis, which complicates purification and reduces yield, making them difficult to use effectively in surface treatment applications.
Innovation Solution
A synthesis method for azole silane compounds that involves reacting an azole compound with a silane compound in a solvent, followed by optional hydrolysis, which results in compounds with improved solubility and stability, free from halides, allowing for higher concentrations and precise control of halide ions in the final product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If azole silane compounds are synthesized using conventional methods with halide-containing educts, then the synthesis can proceed, but halides are released contaminating the product requiring additional purification steps that increase water contamination risk and reduce yield
Solution Approach 1:
The invention extracts and eliminates halide atoms from the synthesis process by using alternative educts without halides. This removes the harmful halide byproducts that would otherwise require purification steps, directly solving the contradiction between ease of manufacture and product purity.
Solution Approach 2:
The invention converts the harmful effect of halide release into a benefit by deliberately choosing educts that do not contain halides. This prevents halide contamination from the start, eliminating the need for purification steps while maintaining simple synthesis procedures.
2Quantity of substance
If azole silane compounds are solubilized in typical solvents at high concentrations, then economic shipping is enabled, but premature polymerization occurs reducing compound stability
Solution Approach 1:
The invention changes the molecular structure parameters of the azole silane compound by introducing specific ether chains and hydrophilic groups. These structural modifications alter the compound's solubility and polymerization behavior, enabling high concentration solubilization without premature polymerization.
Solution Approach 2:
The invention creates a composite molecular structure combining azole silane core with ether chains and hydrophilic groups. This composite structure provides both the desired solubility in typical solvents at high concentrations and resistance to premature polymerization.
3Manufacturing precision
If additional purification steps are added to remove halides, then product purity is improved, but the complexity of the manufacturing process increases and yield is reduced
Solution Approach 1:
The invention performs preliminary action by selecting educts without halides before the synthesis begins. This preventive measure eliminates halide contamination at the source, making additional purification steps unnecessary and simplifying the overall manufacturing process.
4Productivity
If azole silane compounds are used with halide contamination, then the application can proceed, but the reliability of the surface treatment is compromised
Solution Approach 1:
The invention extracts halide contaminants from the final product by using halide-free educts in the synthesis. This ensures high purity azole silane compounds that provide reliable surface treatment performance without compromising productivity.
