Cedar, oil

Rohacts has asaminod the cedar oil distilled from the wood of the Deodar tree, Cedrut dfodarii, a native of the Western Himalayas, which ia widely disfrihnted in Northern India. The samples esamined were of a reddish colour and characteristic balsamic odour. They had the following characters —... 

The fraction of oil of cade boiling at 260° to 280° is converted into cadinene dihydrochloride by saturating its solution in dry ether with dry hydrochloric acid gas. The hydrochloride is separated, dried, and leorystallised, and the hydrochloric acid removed by heating it with aniline or with sodium acetate in glacial acetic acid. The liberated cadinene is rectified in a current of steam. Cadinene from oil of cade is highly laevo-rotatory, the dextro-rotatory variety being obtained from Atlas cedar oil and West Indian sandalwood oil.

Prior to measurement of reflectance, the sample face is covered with cedar oil or commercial immersion oil and then multiple readings are taken of the maximum reflectance of the coal component (e.g., vitrinite) of interest. These values are compared with readings of high-index glass standards (of known reflectance) that are available with reflectance values typically ranging from 0.302 to 1.815%. 

The refractive index of coal can be determined by comparing the reflectance in air with that in cedar oil. A standard test method (ASTM D-2798) covers the microscopic determination of both the mean maximum reflectance and the mean random reflectance measured in oil of polished surfaces of vitrinite and other macerals in coal ranging in rank from lignite to anthracite. This test method can be used to determine the reflectance of other macerals. For vitrinite (various coals), the refractive index usually falls within the range 1.68 (58% carbon coal) to 2.02 (96% carbon coal).

Ancient Egypt is also credited with the use of plasticizers to preserve skin. This was practiced in the mummification process in which the body was dried which made dry skin very fragile and thus a mixture of cedar oil, wax, natron, and gum was rabbed to soften the skin and prevent it from cracking.

The oil usually known as cedar oil or cedar-wood oil is obtained by distillation of the wood of Jiiniperus virgmiana, the Virmnia cedar, one of the family of the Cupressinece. Other cedar-wood ous are occasionally met with, and will be mentioned later, but the present remarks appW to the above-mentioned oil. 

Common/vernacular names American arbor-vitae, cedar leaf, eastern white cedar, northern white cedar, thuja, and white cedar oils. 

Common/vernacular names Cedar oil, cedarwood oil, red cedarwood oil (cedarwood oil Virginia) cedarwood oil Moroccan (cedarwood oil Atlas). 

Cedarwood oil Virginia is obtained by steam distillation of the wood (sawdust, shavings, and other lumber wastes) of/, virginiana, commonly known as red cedar, eastern red cedar, and savin, which is a tree up to about 33 m high growing in North America east of the Rocky Mountains. The tree has many cultivated varieties. This oil is primarily produced in the United States and is most commonly referred to as cedarwood oil or cedar oil it has a sweet pencil wood and balsamic odor.

The Persian name for cedar oil was terpentin or termentin, which became terebinthine in Greece, terebentine in France, turpentyne in England, and turpentine in the United States. In ancient Egypt, amber dissolved in cedar oil was used as a varnish. This fossilized resin was called Bernice, which then became Verenice, Vemix, and in twelfth-century Medieval Latin to varnish. In Greece, Thales called it Electron (the property he observed was static electricity). Amber was first referred to as a fossilized resin from an extinct species of conifer in 1767 by Friedrick Samuel Bock in Attempt at a Natural History of Prussian Amber. 

B.c. Cedar oil was used by Egyptians for coffins, buildings, and sculptures.
