Hello! I am planning a laboratory practice of diesel extraction with GC-FID analysis for students. However, I can't use the common solvents such as acetone or hexane because there a few fume cupboards. Do you know any "safe" nonpolar solvents that I can use for this purpose without requiring a fume cupboard? or do you by chance know a protocol adapted for students?

Thanks in advance for your help.

Best regards,

Diego.

You're not going to find too many non-polar organic solvents that are any more convenient to work with than hexanes. The biggest risk of hexanes is a fire; as long as there are no ignition sources present (hot plates, bunsen burners, etc.) then you should be fine. Most labs have very good airflow which which helps reduce any inhalation risks.

How are they performing this extraction?
