There is a bug in ppchtex.noc. Line 39 says

\let\unexpanded\normalunexpanded

However, on line 181 you load ppchtex. ppchtex assumes that \unexpanded 
is the context macro, not the etex primitive. The easy work around is to 
move the \let\unexpanded\normalunexpanded line to the end of the 
ppchtex.noc. This works fine on my machine.

To the OP: locate ppchtex.noc by kpsewhich ppchtex.noc and copy that file 
to your current directory. Cut line 39 (\let\unexpanded\normalunexpanded) 
and paste it after line 213 (just before the last line). After this change 
the minimal example that you posted works correctly. See if your actual 
tex file now compiles.
