Key Recommendations:

For high-temperature applications: Select solvents with boiling points >250°C

In enclosed spaces: Implement vapor concentration monitoring

When replacing other solvents: Conduct compatibility testing

For environmental compliance: Verify local VOC regulations

These solvents offer superior performance for demanding applications when selected and handled appropriately. Their high solvency power and thermal stability make them indispensable in many industrial processes.
