It takes *chemical stability* as well as volatility to get to the
upper atmosphere.  The chlorine in other chlorinated organic compounds
is chemically removed long before reaching the upper atmosphere.  The
same reactions that eventually cleanse chlorine from the stratosphere
prevent it from ever reaching there except in CFCs.
