Innovation Solution
A novel crystalline potassium salt of ascorbic acid 2-glucoside is produced by dissolving ascorbic acid 2-glucoside in a potassium hydroxide aqueous solution, adding alcohol, and allowing the solution to stand, resulting in a crystal with a unique powder X-ray diffraction pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ascorbic acid 2-glucoside is used in aqueous solutions, then it provides vitamin C activity, but the solution exhibits strong acidity requiring alkali neutralization
Solution Approach 1:
The patent changes the chemical form of ascorbic acid 2-glucoside from its neutral form to a potassium salt form. This parameter change in molecular structure fundamentally alters the pH properties of the compound, allowing it to provide vitamin C activity without exhibiting strong acidity, thereby eliminating the need for alkali neutralization in aqueous solutions.
Solution Approach 2:
The patent introduces potassium as an intermediary element by forming a potassium salt of ascorbic acid 2-glucoside. This intermediary potassium ion acts as a counterion that balances the negative charge of the ascorbate anion, creating a stable salt form that dissolves in water to give a neutral or slightly alkaline solution, thus mediating between the acidic nature of ascorbic acid and the desired neutral pH.
2Adaptability or versatility
If novel crystalline forms of ascorbic acid 2-glucoside are developed, then application options are expanded, but the complexity of characterizing and regulating new forms increases
Solution Approach 1:
The patent changes the physical and chemical parameters of ascorbic acid 2-glucoside by creating a new crystalline potassium salt form. This parameter change in crystal structure and chemical composition provides novel properties that expand application options while maintaining the core vitamin C functionality, allowing differentiation from existing forms without requiring complete re-characterization of basic properties.
