Dinite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
C20H36
Lustre:
Waxy
Hardness:
1
Specific Gravity:
1 - 1.02
Crystal System:
Orthorhombic
Name:
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).
This page provides mineralogical data about Dinite.

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.
