Please help me identify a compound. The boiling point is around 131 C, the Ref Index 1.4569 nD, no halogens?

There are no halogens and it is not aromatic. It is a nonpolar nuetral compound. On the DNP test I got a wierd yellow-orange precipitate. It has the aroma of fly nap and the color but I am pretty sure it is not that. I think it is either a ketone or aldehyde. It may be a aliphatic and/or unconjugated aldehyde.
