Liquid Diamide Solvents via Mixture Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diamide compounds used as solvents are typically solid at room temperature, making them difficult to handle and use, and require hot procedures, which is not ideal for applications such as phytosanitary formulations where low volatility, biodegradability, and low toxicity are desired.
Innovation Solution
Development of mixtures or associations of diamide compounds with specific formulas (la), (Ib), and (Ic) that are liquid at room temperature, comprising hydrocarbon groups and linear divalent alkyl groups, allowing for easier handling and use as solvents, plasticizers, or coalescing agents.

Engineering Contradiction Analysis
1Object-affected harmful factors
If diamide compounds are used as solvents, then favorable toxicological and ecological profiles are achieved, but the compounds are solid at room temperature making them difficult to handle and requiring hot procedures
Solution Approach 1:
The patent combines multiple solid diamide compounds (specifically compounds of formulas Ia, Ib, and Ic with different hydrocarbon chain lengths) to create a mixture that exhibits liquid behavior at room temperature. This merging of components resolves the contradiction by achieving the desired liquid state for easy handling while maintaining the favorable toxicological and ecological profiles of the individual diamide compounds.
Solution Approach 2:
The patent changes the physical state parameter of the diamide compounds from solid to liquid by controlling the molecular structure parameters (hydrocarbon group R and linear divalent alkyl groups) and the mixture composition. This parameter change enables the compounds to be liquid at room temperature for easy handling while preserving their chemical properties and environmental benefits.
2Stability of the object's composition
If diamide compounds with melting points around 80°C are used, then stable chemical structure is maintained, but hot procedures are required which reduces efficiency
Solution Approach 1:
By merging diamide compounds with different melting points and molecular structures into a specific mixture, the patent achieves a liquid state at room temperature that maintains chemical stability while eliminating the need for hot procedures, thereby improving process efficiency and productivity.
Solution Approach 2:
The patent changes the melting point parameter of the diamide mixture from around 80°C to below 35°C by adjusting the molecular structure parameters and composition ratios. This parameter change allows the mixture to remain liquid at room temperature, maintaining chemical stability without requiring hot procedures, thus improving productivity.
3Ease of operation
If conventional solvents are used to achieve liquid state at room temperature, then ease of handling is improved, but volatility and toxicity issues arise
Solution Approach 1:
The patent changes the physical parameters (melting point and state) of the diamide compounds through molecular structure design and mixture composition, achieving liquid state at room temperature with low volatility and favorable toxicological profiles, thus resolving the contradiction between ease of handling and harmful factors.
