1Object-affected harmful factors
If conventional solvents like NMP and DCM are used, then excellent solvation capabilities and industrial performance are achieved, but significant health hazards and environmental damage occur
Solution Approach 1:
The patent changes the chemical parameters of the solvent system by introducing anhydromevalonolactone with different molecular structure and properties compared to conventional NMP and DCM. This bio-derived solvent maintains effective solvation capability while eliminating the toxic harmful factors associated with traditional solvents, achieving both safety and performance requirements
Solution Approach 2:
The patent employs composite solvent formulations that combine anhydromevalonolactone with other compatible solvents or additives. This composite approach allows the system to achieve the solvation performance of conventional solvents while incorporating the safety benefits of the bio-derived anhydromevalonolactone base component
2Object-affected harmful factors
If NMP and DCM are used as primary solvents, then industrial application performance is maintained, but environmental friendliness deteriorates
Solution Approach 1:
The patent converts the challenge of replacing established solvents into a benefit by utilizing anhydromevalonolactone's unique properties. The bio-derived nature and specific solvation characteristics of aMVL provide environmental advantages while maintaining or improving industrial performance in applications such as polymer dissolution and paint stripping
Solution Approach 2:
The patent modifies the solvent system parameters by substituting petrochemical-based NMP and DCM with bio-based anhydromevalonolactone. This parameter change achieves both environmental sustainability and effective industrial performance, demonstrating that green solvents can meet productivity requirements
3Speed
If volatile solvents are used for efficient evaporation and drying, then process speed is improved, but health risks and environmental pollution increase
Solution Approach 1:
The patent changes the volatility parameter of the solvent system by selecting anhydromevalonolactone with appropriate vapor pressure characteristics. This provides a balanced evaporation rate that ensures process efficiency while maintaining lower toxicity levels compared to highly volatile conventional solvents like DCM
Solution Approach 2:
The patent employs a solvent system designed for efficient use and replacement, where anhydromevalonolactone provides effective solvation during the process and can be safely evaporated or disposed of with minimal environmental impact, replacing the need for long-term management of hazardous volatile solvents
