2-Furoic Acid Amide Biocide Solvents for Crystallization Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biocide compositions face challenges in maintaining stability, especially at extreme temperatures, leading to separation or crystallization, which causes issues with filter and nozzle blocking in spray equipment, and often have limited active content and unfavorable eco-toxicological profiles.
Innovation Solution
The use of 2-Furoic acid and Tetrahydro-2-furoic acid amides as solvents or co-solvents, which can dissolve a wide range of biocides up to 15% better than traditional amides, combined with oil components and emulsifiers to create stable emulsifiable concentrates, allowing for higher active content formulations regardless of biocide chemical structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional amides are used as solvents, then the biocide compositions can be formulated, but the solubility is limited and crystallization occurs at extreme temperatures
Solution Approach 1:
The patent changes the chemical parameters of the solvent system by replacing traditional amides with 2-furoic acid and tetrahydro-2-furoic acid amides. This parameter change enables higher active content dissolution (up to 15% improvement) and prevents crystallization at extreme temperatures, thereby resolving the contradiction between quantity of substance and stability.
2Productivity
If higher active content is formulated, then the productivity increases, but the risk of crystallization and filter blocking increases
Solution Approach 1:
The patent introduces 2-furoic acid and tetrahydro-2-furoic acid amides as intermediary substances that mediate between the active biocide components and the formulation system. These intermediaries enhance solubility and prevent crystallization, allowing higher active content formulation without compromising spray equipment reliability by preventing filter and nozzle blocking.
3Ease of manufacture
If conventional solvents are used, then the formulation process is simple, but the eco-toxicological profile is unfavorable
Solution Approach 1:
The patent changes the chemical composition parameters by substituting conventional solvents with 2-furoic acid and tetrahydro-2-furoic acid amides. This substitution maintains formulation simplicity while significantly improving the eco-toxicological profile, as these new solvents exhibit better environmental compatibility and safety characteristics.
