#11 sovlent... just frowned upon or bad?

[ICanHas]

Do you guys remember the #11 solvent in 30 lb jugs that just look like R22 except its orange?

It's not in pourable drum like R11 sold for chillers.

came across some at garage sale.

Is the use of existing stock for the then intended purpose rather frowned upon.. or is it straight up environmental crime?

Sure. It was an accepted method for cleaning up burnouts. When better suction cores became available it wasn't used as much. I never liked it much as it sometimes left sludge behind in horizontal coils and piping. I almost died when I was in a basement mech room changing out driers and the crew began to blow down the system with r11. It ended up in the mech room. I git lucky and floated out the door.
I'm not sure of EPA's position but if not used as a refrigerant but a cleaning fluid it might be ok.

It is perfectly legal to use existing quantities as a solvent, it just can't be manufactured or imported for use in the USA anymore.

If I ran across some at a garage sale, I'd buy it if the price was reasonable.
