Soluble only in concentrated sulfuric acid. 1348 Behaviour typical of an alkene, polyalkylaromatic or O-containing compound. Solvent is deuterochloroform. ЙwIA{|I4)+ FPgz 132023303334383941424344454648495154 All the protons are very similar; they are saturated and aliphatic. # dummy ms # # # # # No extra elements were detected. 212531353941424349264048 The unknown does not contain N, S, or halogens. Burnt with a clear flame leaving no residue. # Typical of a saturated organic compound. Below room temperature. # This behaviour is consistent with the unknown being a liquid.
