what can i use in place of benzene?

i was wondering if anyone would know what, if anything, could be used to replace the benzene needed in an extraction. I do not have the credentials to buy them from a lab and my other connections have been exhausted. I need around 3 liters.

 

Toluene. It's much less toxic so is often used in the lab where benzene would have been used anyway.

 

or d-limonene. much less toxic than either toulene or benzene.

 

xylene or toluene
