In my experience, peroxide formers tend to get cloudy if peroxides have formed. If it's cloudy, don't move it, if it's just a solid, it's probably the acid derivative.

Ultimately, if you're unsure or uncomfortable, you should call a hazardous waste removal company. I always find it's better to be safe than sorry.

I agree most likely benzoic acid.

It has most likely just oxidized up to benzoic acid.

I just did a lab safety inspection and found a bottle of Benzaldehyde with crystal formation. The bottle is dated back to 5-25-1989. I am not sure if this is peroxide or just polymer being formed. What are your thoughts? If it is peroxide, what is the proper protocol for handling it?

Thanks,

Wayne
