Isopropyl Biphenyl

urenthesage - 17-8-2024 at 08:31

I scrap electronics and run into a fair number of capacitors that contain Isopropyl Biphenyl, but can find very limited information on this compound. Has anyone worked with it before, and is there a solvent I could use to dissolve it? Ive tried things like gasoline and ethanol to dissolve it with little success. Any information or suggestions would be appreciated.

I've used biphenyl and di-t-butylbiphenyl in the lab, which should have similar solubilities. They're poorly soluble in ethanol (but decently so in hot ethanol- good for recrystallization). Moderately soluble in hexanes, especially if heated.

Thank you. I have some junk ethanol I can purify to try that.

If the ethanol doesn't do it and you're working with OTC stuff, ("non-chlorinated") brake cleaner might be worth a try. Acetone and heptanes is a common formulation, and with a bit of heat should do the job.
