Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional hydrosilylation reaction methods are used, then the reaction can proceed, but the reaction is incomplete and yield is low
Solution Approach 1:
The invention changes the chemical environment parameters by introducing acidic compounds or acidic compound precursors into the hydrosilylation reaction system. This parameter change activates the carbonyl group-containing alicyclic olefin compound, making it more reactive toward the hydrosilane compound, thereby completing the reaction more fully and increasing yield
Solution Approach 2:
The acidic compound or acidic compound precursor acts as an intermediary substance that facilitates the reaction between the hydrosilane compound and the carbonyl group-containing alicyclic olefin compound. The intermediary activates the olefin compound, enabling more complete reaction and higher productivity
2Productivity
If conventional hydrosilylation reaction methods are used, then the reaction can proceed, but reactivity is poor and purification is difficult
Solution Approach 1:
By changing the reaction parameters through acidic compound addition, the reaction proceeds more completely with fewer unreacted starting materials remaining. This reduces the complexity of purification operations and makes the manufacturing process easier
Solution Approach 2:
The invention converts the potential harm of incomplete reaction (which creates purification difficulties) into a benefit by using acidic compounds to drive the reaction to completion, thereby eliminating the need for complex purification steps
