structural formula may be written as: (CH2)3C(CH3)2C(CH3)C(H)(CH2)2C(H)C(H)(CH2)3C(CH3)(C2H5)
Specific Gravity:
1 - 1.02
Crystal System:
The name "Dinite" was chosen by Prof. G. Meneghini in honour of Prof. Olinto Dini (1802-1866), (Italian teacher and professor of physics, University of Pisa), who found the mineral.
This naming of dinite was reported by Petri (1852).
Chemically: isopimarane, also known as (13α)-pimaran, (13α)-pimarane, and systematically (4aR,4bS,7S,8aS,10aS)-7-ethyltetradecahydro-1,1,4a,7-tetramethylphenanthrene.

Other InformationHide

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 Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
