Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oxidizing liquids for chemiluminescence have a low flash point, making them hazardous and subject to strict regulations, while aromatic solvents like phthalates are safety concerns and environmental hormones, necessitating a safer alternative that maintains chemiluminescent performance.
Innovation Solution
A phthalate-free oxidizing liquid with a flash point of 60° C. or higher, composed of a mixture of solvents such as triethyl citrate, acetyl tributyl citrate, benzyl benzoate, and others, which enhances fire safety and compatibility with hydrogen peroxide and fluorescent substances, ensuring compliance with aviation and fire regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional oxidizing liquid containing alcohol (ethanol) is used, then chemiluminescent performance is maintained, but flash point becomes low (20-40°C) causing fire hazard
Solution Approach 1:
The patent changes the physical and chemical parameters of the solvent system by replacing alcohol-based solvents with non-alcoholic solvents (acetyl tributyl citrate, benzyl benzoate, dipropylene glycol dimethyl ether). This parameter change increases the flash point from 20-40°C to above 100°C, eliminating fire hazards while maintaining chemiluminescent performance through proper solvent selection and composition ratios.
Solution Approach 2:
The patent uses a composite solvent system comprising multiple non-alcoholic solvents (acetyl tributyl citrate, benzyl benzoate, dipropylene glycol dimethyl ether) in specific composition ratios. This composite material approach combines the advantages of each solvent to achieve both high flash point (>100°C) and effective chemiluminescent reaction, resolving the contradiction between safety and performance.
2Reliability
If phthalate solvents are used, then chemiluminescent performance is maintained, but environmental safety deteriorates due to environmental hormone concerns
Solution Approach 1:
The patent extracts and removes phthalate solvents from the oxidizing liquid composition, replacing them with non-phthalate alternatives (acetyl tributyl citrate, benzyl benzoate, dipropylene glycol dimethyl ether). This extraction eliminates the environmental hormone concerns associated with phthalates while maintaining the necessary chemiluminescent performance through the alternative solvent system.
3Object-generated harmful factors
If non-aromatic solvents are used, then environmental safety is improved, but flash point may be reduced affecting fire safety
Solution Approach 1:
The patent employs a composite solvent system combining three non-aromatic solvents (acetyl tributyl citrate, benzyl benzoate, dipropylene glycol dimethyl ether) in optimized ratios. This composite approach ensures that the mixture maintains a flash point above 100°C, simultaneously achieving environmental safety by being non-aromatic and fire safety through high flash point, thus resolving the contradiction between these two safety aspects.
