http://en.wikipedia.org/w/api.php?action=query&ppprop=staticredirect|displaytitle&prop=pageprops&titles=C5H10O2 returns no displaytitle although it exists. staticredirect does not exists in this case. Requesting only displaytitle returns correct response: http://en.wikipedia.org/w/api.php?action=query&ppprop=displaytitle&prop=pageprops&titles=C5H10O2
ppprop does not take multiple props. In your query, it's actually looking for a prop named "staticredirect|displaytitle". I don't see why not, since similar parameters like clcategories and pltitles take multiple values, but as it stands it doesn't.
