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
