Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The industry seeks new solvents for phytosanitary applications with improved properties such as low volatility, good biodegradability, low toxicity, and favorable ecological profiles, particularly for use in preparing emulsifiable concentrates and other formulations of phytosanitary active ingredients, as existing solvents may interact with pesticides and pose stability issues during dilution and storage.
Innovation Solution
Development of esteramide compounds of the formula R1-OOC-A-CONMe2, where A is a covalent bond with alkyl groups of 5 to 15 carbon atoms, which do not exhibit acidity, allowing them to be used as solvents without interacting with pesticides, and can be prepared through specific reaction processes involving basic or acid catalysts, offering advantages in phytosanitary formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional solvents are used for phytosanitary formulations, then the formulations can be prepared, but the solvents may interact with pesticides and pose stability issues during dilution and storage
Solution Approach 1:
The patent introduces esteramide compounds as intermediary substances that serve as solvents between the pesticide active ingredients and the formulation matrix. These esteramides act as mediators that do not interact adversely with pesticides, providing a stable medium for formulation preparation and storage without causing harmful interactions.
Solution Approach 2:
The patent modifies the chemical parameters of the solvent by using esteramide compounds with specific molecular structures (formula I) that have controlled polarity and reactivity. By changing the chemical parameters of the solvent to be less reactive and more stable, the formulation maintains reliability during dilution and storage without adverse solvent-pesticide interactions.
2Object-affected harmful factors
If new solvents are developed with improved toxicological and ecological profiles, then environmental friendliness is improved, but manufacturing complexity increases
Solution Approach 1:
The patent changes the chemical parameters of the solvent by selecting esteramide compounds with specific molecular weights, polarities, and structural features (formula I) that inherently provide favorable toxicological and ecological profiles. These parameter changes in the solvent molecules enable improved environmental performance while maintaining manageable manufacturing processes through established chemical synthesis routes.
3Object-affected harmful factors
If solvents with low volatility are used, then ecological profile is improved, but solubility of phytosanitary active ingredients may be reduced
Solution Approach 1:
The patent optimizes the physical and chemical parameters of the esteramide compounds (formula I) to achieve a balance between low volatility and high solubility. By adjusting molecular weight, functional groups, and structural features of the esteramides, the patent creates solvents that maintain low vapor pressure for ecological benefits while preserving adequate solubility capacity for phytosanitary active ingredients.
