Other Information

IR Spectrum:The IR spectrum was obtained with a Perkin-Elmer FTIR 1600 spectrometer using a solution of dinite in "Nujol". The spectrum presents the typical features of a saturated hydrocarbon.
Thermal Behaviour:The fusion point was measured at 33-34° C, using Kopffler apparatus.
Health Warning:No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
