AC systems have either R12 or 134A refrigerant in them depending on the year of the car. On a working AC system, the refrigerant is either in a liquid or vapor state depending on where in the cycle it is. If the compressor has not worked in years, the system could still have a charge of refrigerant left.
You should have had the system drained by a shop that can recover the refrigerant before you removed the compressor.
Oh well, so much for our ozone layer
