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 novel 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.
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 sulfonic acid groups into the peroxycarboxylic acid structure, fundamentally changing the chemical parameters of the molecule. This structural modification transforms the compound from hydrophobic and unstable to hydrophilic and storage-stable, while simultaneously eliminating the unpleasant odor associated with conventional peroxycarboxylic acids
Solution Approach 2:
The invention creates a composite molecular structure combining the peroxycarboxylic acid functional group with sulfonic acid groups. This composite structure integrates the desirable bleaching and antimicrobial properties of peroxycarboxylic acids with the water solubility, stability, and low-odor characteristics of sulfonic acid compounds
2Ease of operation
If conventional peroxycarboxylic acids are used, then they exhibit antimicrobial and bleaching activity, but they are water insoluble and have limited storage stability
Solution Approach 1:
The sulfonation of the peroxycarboxylic acid structure fundamentally alters its physical and chemical parameters. The introduction of polar sulfonic acid groups dramatically increases water solubility while the resulting salt forms exhibit enhanced storage stability, resolving the contradiction between solubility and stability
3Productivity
If conventional peroxycarboxylic acids are used as bleaching agents, then they provide effective bleaching, but they have unpleasant odor and limited storage stability
Solution Approach 1:
The chemical structure modification through sulfonation changes the volatility and odor profile of the compound while preserving the reactive peroxycarboxylic acid group responsible for bleaching activity. The sulfonic acid groups do not interfere with the bleaching mechanism but eliminate the unpleasant odor
Solution Approach 2:
The invention effectively extracts or removes the harmful odor property from the peroxycarboxylic acid molecule by adding sulfonic acid groups, separating the desirable bleaching function from the undesirable odor characteristic
