Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning methods for surfaces in food manufacturing and drug production often rely on phosphates, which pose ecological concerns, and require oxidizing agents like potassium permanganate that can be unstable when used for detecting organic substances.
Innovation Solution
A composition comprising salts of permanganic acid, ferric acid, and chromic acid, combined with organic phosphonates and persulphates, which stabilizes the oxidizing agents and allows for effective surface cleaning and detection of organic substances without using phosphates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phosphates are used in cleaning agents, then cleaning effectiveness is improved, but ecological problems arise
Solution Approach 1:
The patent replaces phosphates with organic phosphonates having specific chemical structures (formula I) where R1 is a mono-substituted or multiple-substituted or unsubstituted C1-C12 alkyl moiety, C3-C10 cycloalkyl moiety or C6-C14 aryl moiety. This parameter change in chemical composition maintains cleaning effectiveness while eliminating ecological harm associated with phosphates
Solution Approach 2:
The patent uses organic phosphonates as a substitute that, while serving the same function as phosphates, do not persist in the environment. The organic phosphonates perform their water softening and cleaning enhancement function and then degrade, unlike phosphates which accumulate and cause ecological problems
2Measurement precision
If oxidizing agents like potassium permanganate are used for detecting organic substances, then detection capability is improved, but stability of the composition deteriorates
Solution Approach 1:
The organic phosphonate acts as an intermediary substance that mediates between the oxidizing agent and the environment. It stabilizes the oxidizing agent (potassium permanganate, ferric acid, or chromic acid) through complexation or protective interaction, preventing premature decomposition while allowing the oxidizing agent to maintain its detection capability
Solution Approach 2:
The patent creates a composite cleaning and detection composition that combines oxidizing agents with organic phosphonates. This composite formulation leverages the stabilizing effect of the organic phosphonate on the oxidizing agent, resulting in a composition that maintains both detection precision and compositional stability during storage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively stabilizes the oxidizing agents, enhancing their storability and allowing for reliable detection of organic substances, while avoiding the ecological issues associated with phosphates.
Implementation Method 1
The organic phosphonates used according to the invention are in particular characterized by being able to significantly increase the stability and, hence, the storability of the salts of the permanganic acid, ferric acid and chromic acid present therein
Implementation Method 2
salts of the permanganic acid and in particular potassium permanganate... which upon reduction thereof with, for example, organic compounds is able to change the colour of the corresponding solutions
Implementation Method 3
Due to the colour change conditioned by the reduction of the oxidizing agent, it is, hence, possible to determine whether organic compounds are present in a solution or on a surface
Implementation Method 4
c) at least one persulphate
