Found in the trees and bark of Cinnamomum carphora sieh (Fam. iMuraceae) and prepared by fractional distillation of crude camphor oil after the camphor has been crystallized out a white, viscous liquid with cineole as the principal ingredient along with monoterpenes (FCTXAV 11,1011,73),... 

Over in China, Thailand, Japan, etc. grows the camphor tree. They chop up the bark, leaves and whatever. They then steam distill the stuff to get a crude camphor extract. When this extract cools, a motherlode of white camphor (the actual chemical compound called camphor) crystals form. These crystals are separated by fdtration and represent about 50% of the crude extract. The other 50% that doesn t crystallize is what is termed as camphor oil. It is this oil that is the camphor oil of commerce. This crude oil is also what is technically called the essential oil of camphor. ... 

White camphor oil The first distilled fraction that is clear to clear-white and that has a boiling range of 160-185C. It is mainly composed of cineoles. 

Occurs in all parts of the camphor tree Cin-namomum camphora. White solid, penetrating odour sublimes appreciably at ambient temperature readily volatile in steam. Teaspoonful of camphorated oil said to produce serious toxic effects in an adult. Children 1 g camphor profuse dermal, gastric and renal haemorrhaging. CNS deterioration, death. Liver and kidney fatty degeneration. Rapid absorption from gut lipid-soluble. Convulsions status epilepticus. 

White camphor oil is the first distillation fraction (ca. 20% of the crude camphor oil). It is a colorless or almost colorless liquid with a cineole-like odor. 

In comparing the results of Ae two sets of experiments, it will be seen that red thyme was 41% less effective against LBAM than white thyme and in controlling Flour Beetle there was, in comparison, a 65% difference between the two botanical cultivars. Furthermore, the effectiveness of the essential oils drops off rapidly so that only eucalyptus, camphor, and white thyme may be considered as useful canidates. Oddly, black pepper was inactive in these assays, while in earlier work certain components of this commodity have been shown to have strong insecticidal properties. The earliest report being in 1943 (12), which was followed not only by later reports of insecticidal...

This oil is often blended with a- and p thujones from cheaper sources like Thuja orientalis. Furthermore camphor or white camphor oil and camphene are used. GC-MS method is used to detect these adulterations. 

ISO standard 3757 shows character and data for this oU. This very complex oil is adulterated by gurjun balm oil (see text). Blending is done by patchouli terpenes, cedarwood oil, pepper oil, white camphor oil, and guaiac wood oil. Detection is done by GC MS. 

ISO standard 4719 shows character and data for that oil. Adulteration is done by white camphor oil, 1,8-cineole distilled from eucalyptus oil, synthetic camphor, and linalool. Blending is done with ter-penes from eucalyptus oil, turpentine oil, n-bornyl acetate, lavandin, rosemary oil, HO leaf oil, and a terpineol. Detection can be made by GC MS and by multidimensional chiral separation. Ravid (1992) mentions the chiral ratio of terpinen 4 ol as (4S) (+) terpinen-4-ol 93% (4I -(-)-terpinen 4-ol 7%. 

Camphor oils refer to the by-products during the extracting process of camphor from camphorwood [2]. The physical properties of various camphor oils can be seen from Table 3.1. Compared with pine oils, the selectivities of those camphor oils with low-boiling fractions (such as white oil) are relatively better. The frothing performances of those camphor oils with high-boiling fractions (such as red oil) are relatively stronger. 

Camphor, a bicyclic monoterpene, is extracted from the woods of Cinnamomum camphora, a tree located in Southeast Asia and North America. Furthermore, it is also one of the major constituents of the essential oil of common sage (Salvia officinalis). Solid camphor forms white, fatty crystals with intensive camphoraceous odor and is used commercially as a moth repellent and preservative in pharmaceuticals and cosmetics (Wichtel, 2002). In dogs, rabbits, and rats, camphor is extensively metabolized whereas the major hydroxylation products of d- and L-camphor were 5-endo-md 5-ex -hydroxycamphor. A small amount was also identified as 3-e do-hydroxycamphor (Figure 8.2). Both 3- and 5-bornane groups can be further reduced to 2,5-bornanedione. Minor biotransformation steps also involve the reduction of camphor to borneol and isoborneol. Interestingly, all hydroxy-lated camphor metabolites are further conjugated in a Phase II reaction with glucuronic acid... 

Light camphor oil is the lowest boiling portion of the oil, and consists principally of terpenes. Its specific gravity usually lies betveeen 0 870 and 0 885, rarely up to 0 910. It is water white and resembles-turpentine in general characters. 

Camphor was originally obtained from the camphor tree Lauras eamphora in which it appeared in the optically active dextro-rotary form. Since about 1920 the racemic ( ) mixture derived from oil of turpentine has been more generally used. By fractional distillation of oil of turpentine the product pinene is obtained. By treating this with hydrochloric acid, pinene hydrochloride (also known as bomyl chloride) may be produced. This is then boiled with acetic acid to hydrolyse the material to the racemic bomeol, which on oxidation yields camphor. Camphor is a white crystalline solid (m.p. 175°C) with the structure shown in Figure 22.3. 

It is found to a considerable extent in oils of sassafras, camphor, and Ilicitim religiosum. When pure it is a white crystalline mass at low temperatures, melting at + 11°. At ordinary temperatures it forms a colourless oil of characteristic, pleasant odour, and having the following characters —... 

The 2,5-dimethoxy-3,4-methylenedioxy pattern. The parent allyl benzene is apiole (with a final e ) or parsley camphor, and it is the major component of parsley seed oil. Its conjugated isomer is called isoapiole, and they are valuable as the chemical precurors to the amination product, DMMDA. Whereas both of these essential oils are white solids, there is a green oily liquid that... 

It has also been found that certain aldehydes, ketones and carboxylic acids esters form well defined products with nitric acid (Reddelien [5]). For example, bemzaldehyde with 60% nitric acid gives a colourless, unstable oil, and cinnamic aldehyde forms fairly stable white crystals, melting at 60-61°C, with 65% nitric acid. Acetophenone, benzophenone, fluorenone, phenanthrenoquinone and camphor give similar addition products. 

To Hake Hatches Without Sulphur. To obviate the use of sulphur for igniting tho wood of the match, the ends of the matches aro first slightly charred by rubbing them against a red hot iron plate, and then dipped into as much white wax, melted in a suitable vessel, as will cover the bottom about i inch in depth. Or they may be dipped into camphorated spirit. Or into a solution of 1 ounce Venice turpentine and k ounce camphor, in pint oil of turpentine, with a little gum-benzoin and eascarilla by way of perfume. After any of the above preparations the matches are ready for dipping in the phosphorus paste. 

Phenyl Salicylate. Phenyl salicylate, salol. occurs as fine white crystals or a white crystalline powder with a characteristic taste and a faint, aromatic odor. It is insoluble in water (1 6.700). slightly soluble in glycerin, and soluble in alcohol (1 6). ether, ehlorofomi. aeetone. or fixed and volatile oils. Dump or eutectic mixtures form readily with many organic material.s. such as thymol, rtrcnthol. camphor, chloral hydrate, and phenol.
