Alkanolamine Salt Dicamba Liquid Stability Low Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicide formulations with amine salts often require high water content to remain in a single phase, leading to increased transportation costs and reduced efficacy due to solidification at ambient conditions, which impairs leaf penetration and active treatment duration.
Innovation Solution
Development of an herbicidal composition comprising an alkanolamine salt derived from the reaction of alkanolamine compounds with dicamba, which remains a single phase liquid for at least one week under specific test conditions, reducing the need for excessive water and maintaining stability with low solvent concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If high water content is used to maintain single phase liquid composition, then the composition remains liquid at ambient conditions, but transportation costs increase
Solution Approach 1:
The patent changes the chemical composition parameters by using specific amine salts (alkanolamine salts) with controlled water content (less than 5 wt.%) to achieve single phase liquid stability without requiring high water content. This parameter optimization resolves the contradiction between stability and quantity of substance.
2Stability of the object's composition
If high water content is used to dissolve amine salt solids, then a single phase liquid is formed, but transportation costs increase due to shipping more water
Solution Approach 1:
The patent optimizes the water content parameter to less than 5 wt.% and selects specific amine salt compositions that form single phase liquids at these low water contents. This eliminates the need to ship large volumes of water while maintaining single phase stability.
3Stability of the object's composition
If amine salt solidifies at ambient conditions, then formulation stability is improved, but leaf penetration and active treatment period are impaired
Solution Approach 1:
The patent changes the physical state parameter by formulating single phase liquid compositions that remain liquid at ambient conditions through optimized amine salt selection and water content control (less than 5 wt.%). This resolves the contradiction by maintaining both stability and extended active treatment period.
4Quantity of substance
If maximum loading of active salt is increased, then efficacy is improved, but the composition may solidify at ambient conditions
Solution Approach 1:
The patent optimizes multiple parameters simultaneously: selects specific amine salts, controls water content to less than 5 wt.%, and adjusts composition ratios to achieve maximum active salt loading while maintaining single phase liquid stability at ambient conditions.

AI summary
The invention is a herbicidal composition containing an alkanolamine salt of an dicamba capable of remaining as a single phase liquid over a period of at least 1 week and containing low amounts of water and high loadings of the salt. Such herbicidal compositions are capable of remaining liquid in the absence of high amounts of water, thereby enhancing their capacity to remain liquid over an extended period of time when exposed to environmental conditions to improve their effectiveness to transport the active salt through a leafy substrate and can reduce transportation costs by increasing the salt loading without compromising the stability of the composition.
