Polycyclic Aminosilane Compounds for Enhanced Additive Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silane compounds with a single amino group per molecule exhibit insufficient additive effects when used as silane coupling agents, surface treating agents, resin additives, and adhesives, and they produce a significant amount of low-boiling alcohols, contributing to environmental concerns.
Innovation Solution
A polycyclic aminosilane compound with a specific structure is developed, which is synthesized by reacting an epoxy-containing organoxysilane with a hydroxyl-containing amine, followed by distillation in the presence of a catalyst, to enhance additive effects and minimize low-boiling alcohol production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If silane compounds with a single amino group per molecule are used, then the molecular structure is simple and easy to manufacture, but the additive effects are insufficient
Solution Approach 1:
The invention divides the single amino group function into multiple amino groups within the same molecule by introducing a polycyclic structure containing multiple nitrogen atoms. This segmentation approach allows the molecule to exhibit enhanced additive effects while maintaining a systematic structural design that is still feasible to manufacture.
Solution Approach 2:
The patent embeds multiple amino-containing rings within a silane molecular framework, creating a nested structure where the polycyclic core contains multiple nitrogen atoms. This nested architecture enables the molecule to deliver multiple functional effects simultaneously while maintaining structural integrity and manufacturability.
2Reliability
If organoxysilane compounds react with moisture to form hydroxyl groups, then the additive effects due to functionality introduction increase, but low-boiling alcohols are produced causing environmental concerns
Solution Approach 1:
The invention extracts the problematic low-boiling alcohol byproduct from the reaction system by designing a molecular structure where the xysilane group reacts to form high-boiling alcohol instead. This extraction principle eliminates the harmful low-boiling alcohol while preserving the beneficial hydroxyl group formation that enhances additive effects.
Solution Approach 2:
The patent converts the harmful effect of alcohol production into a beneficial outcome by designing the xysilane group to produce high-boiling alcohol instead of low-boiling alcohol. The high-boiling alcohol remains in the system as a useful byproduct rather than becoming an environmental pollutant, thus converting a harmful process into a beneficial one.
