Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for solvent compounds that are renewably sourced, exhibit high solvency, and have a desirable health and safety profile, particularly in terms of toxicity and volatile organic compounds (VOCs), as traditional high VOC solvents are environmentally harmful and pose health risks.
Innovation Solution
The development of olefinic ester compounds, specifically esters of C10-18 carboxylic acids with one or more carbon-carbon double bonds, which are used in cleaning compositions for surfaces, textiles, and food-related materials, derived from natural oils through catalytic olefin metathesis, offering improved solvency and reduced toxicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional high VOC solvents (aromatics, ketones, halogenated organics) are used, then high solvency is achieved, but environmental harm and health risks increase
Solution Approach 1:
The patent changes the chemical parameters of solvent molecules by introducing carbon-carbon double bonds into ester structures derived from renewable feedstocks. This structural modification enables the solvents to achieve high solvency comparable to traditional solvents while simultaneously reducing VOC content and improving environmental compatibility, thus resolving the contradiction between solvency and environmental harm.
Solution Approach 2:
The patent creates composite solvent systems by combining olefinic ester compounds with specific physical and chemical properties. These composite materials integrate the benefits of renewable sourcing, low VOC content, and high solvency into a unified solvent system that outperforms traditional single-component solvents in both effectiveness and environmental safety.
2Object-affected harmful factors
If renewable solvents (fatty acid alkyl esters, terpene oils) are used, then environmental friendliness is improved, but solvency performance deteriorates
Solution Approach 1:
The patent modifies the molecular parameters of renewable ester solvents by incorporating carbon-carbon double bonds through olefin metathesis reactions. This structural change enhances the solvent properties of renewable feedstocks, enabling them to achieve solvency levels comparable to or exceeding traditional solvents while maintaining their environmental advantages, thus resolving the contradiction between environmental friendliness and solvency.
3Object-affected harmful factors
If solvents with low toxicity are developed, then health safety is improved, but solvency may be compromised
Solution Approach 1:
The patent changes the molecular structure of esters by introducing carbon-carbon double bonds, which simultaneously improves biodegradability and reduces toxicity while maintaining or enhancing solvency. The resulting olefinic ester compounds achieve a balanced profile where low toxicity does not come at the expense of cleaning effectiveness.
