Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional peroxycarboxylic acids have limitations such as limited storage stability, water insolubility, and an unpleasant odor, which restrict their use as effective antimicrobial and bleaching agents.
Innovation Solution
Development of sulfoperoxycarboxylic acids that are storage stable, low or odor-free, and water soluble, derived from non-petroleum based renewable oils, suitable for use as bleaching, antimicrobial, and coupling agents, including low-temperature bleaches and pH-optimized peroxygen bleaches for textiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional peroxycarboxylic acids are used as bleaching and antimicrobial agents, then they provide effective antimicrobial and bleaching properties, but they have limited storage stability, water insolubility, and unpleasant odor
Solution Approach 1:
The patent introduces sulfonate groups (-SO3Na) into the peroxycarboxylic acid structure, fundamentally changing the chemical parameters of the molecule. This structural modification transforms the compound from water-insoluble to water-soluble while maintaining stability and eliminating odor, directly resolving the technical contradictions
2Reliability
If conventional peroxycarboxylic acids are used, then they exhibit antimicrobial and bleaching activity, but they have limited storage stability
Solution Approach 1:
The invention creates a composite molecular structure combining the peroxycarboxylic acid functional group with sulfonate groups and hydrocarbon chains. This composite structure integrates the antimicrobial/bleaching properties of peracids with the stability and solubility properties of sulfonated compounds, achieving both high stability and effective concentration
3Object-generated harmful factors
If conventional peroxycarboxylic acids are used as bleaching agents, then they provide bleaching action, but they have unpleasant odor
Solution Approach 1:
The sulfonation modification changes the physical and chemical parameters of the peroxycarboxylic acid, including odor characteristics. The resulting sulfoperoxycarboxylic acid compounds are described as odorless or having minimal odor while maintaining full bleaching efficiency, thus resolving this contradiction
4Ease of manufacture
If conventional peroxycarboxylic acids are used, then they provide antimicrobial properties, but they have water insolubility
Solution Approach 1:
By introducing ionic sulfonate groups into the molecular structure, the patent fundamentally changes the solubility parameters of the compound. The resulting sulfoperoxycarboxylic acids are highly water-soluble while retaining antimicrobial efficacy, as the active peroxycarboxylic acid functional group remains intact
