Kafoor oil

Postby Neran В» 08.03.2020

Marriage is in fact much more influential and central to society than the (however wrong) discrimination of one class of people over another.

It is found in the wood of the camphor laurel Cinnamomum camphora , a large evergreen tree found in Asia particularly in Sumatra and Borneo islands, Indonesia and also of the unrelated kapur tree Dryobalanops sp. It also occurs in some other related trees in the laurel family , notably Ocotea usambarensis. Rosemary leaves Rosmarinus officinalis contain 0. Camphor can also be synthetically produced from oil of turpentine. The molecule has two possible enantiomers as shown in the structural diagrams.

The structure on the left is the naturally occurring R -form, while its mirror image shown on the right is the S -form. It is used for its scent, as an ingredient in cooking mainly in India , as an embalming fluid , for medicinal purposes, and in religious ceremonies. It was first used by Hindus from very ancient times and called "Karpoora Aarathu", also when religions like Buddhism and Jainism flourished.

In Old Malay it is known as kapur Barus , which means "the chalk of Barus". Barus was the name of an ancient port located near modern Sibolga city on the western coast of Sumatra island. Even now, the local tribespeople and Indonesians in general refer to aromatic naphthalene balls and moth balls as kapur Barus.

Camphor has been produced as a forest product for centuries, condensed from the vapor given off by the roasting of wood chips cut from the relevant trees, and later by passing steam through the pulverized wood and condensing the vapors. In Robert Kennedy Duncan, an industrial chemist and educator, related that the Imperial Japanese government had recently — tried to monopolize the production of natural camphor as a forest product in Asia but that the monopoly was prevented by the development of the total synthesis alternatives, [11] which began in "purely academic and wholly uncommercial" [11] form with Gustav Komppa's first report "but it sealed the fate of the Japanese monopoly […] For no sooner was it accomplished than it excited the attention of a new army of investigators—the industrial chemists.

The patent offices of the world were soon crowded with alleged commercial syntheses of camphor, and of the favored processes companies were formed to exploit them, factories resulted, and in the incredibly short time of two years after its academic synthesis artificial camphor, every whit as good as the natural product, entered the markets of the world […]. And yet artificial camphor does not—and cannot—displace the natural product to an extent sufficient to ruin the camphor-growing industry.

Its sole present and probable future function is to act as a permanent check to monopolization, to act as a balance-wheel to regulate prices within reasonable limits. The organic chemists at DuPont replied by synthesizing camphor from the turpentine of Southern pine stumps, with the result that the price of industrial camphor sold in carload lots in was between 32 cents and 35 cents a pound.

The background of Gustaf Komppa 's synthesis was as follows. In the 19th century, it was known that nitric acid oxidizes camphor into camphoric acid. Haller and Blanc published a semisynthesis of camphor from camphoric acid.

Although they demonstrated its structure, they were unable to prove it. The first complete total synthesis of camphoric acid was published by Komppa in Its inputs were diethyl oxalate and 3,3-dimethylpentanoic acid , which reacted by Claisen condensation to yield diketocamphoric acid. Methylation with methyl iodide and a complicated reduction procedure produced camphoric acid.

William Perkin published another synthesis a short time later. Previously, some organic compounds such as urea had been synthesized in the laboratory as a proof of concept , but camphor was a scarce natural product with a worldwide demand.

Komppa realized this. He began industrial production of camphor in Tainionkoski , Finland , in with plenty of competition, as Kennedy Duncan reported. Camphor can be produced from alpha-pinene , which is abundant in the oils of coniferous trees and can be distilled from turpentine produced as a side product of chemical pulping. With acetic acid as the solvent and with catalysis by a strong acid, alpha-pinene readily rearranges into camphene , which in turn undergoes Wagner-Meerwein rearrangement into the isobornyl cation, which is captured by acetate to give isobornyl acetate.

Hydrolysis into isoborneol followed by oxidation gives racemic camphor. By contrast, camphor occurs naturally as D -camphor, the R - enantiomer. In biosynthesis , camphor is produced from geranyl pyrophosphate , via cyclisation of linaloyl pyrophosphate to bornyl pyrophosphate, followed by hydrolysis to borneol and oxidation to camphor.

Camphor can also be reduced to isoborneol using sodium borohydride. In , K. Chakrabarti and coworkers from the Indian Association for the Cultivation of Science , Kolkata , prepared diamond thin film using camphor as the precursor for chemical vapor deposition. In , carbon nanotubes were successfully synthesized using camphor in chemical vapor deposition process. The sublimating capability of camphor gives it several uses. The first significant manmade plastics were low-nitrogen or "soluble" nitrocellulose pyroxylin plastics.

In the early decades of the plastics industry , camphor was used in immense quantities [11] : as the plasticizer that creates celluloid from nitrocellulose, in nitrocellulose lacquers and other plastics and lacquers.

Camphor is believed to be toxic to insects and is thus sometimes used as a repellent. Camphor crystals are sometimes used to prevent damage to insect collections by other small insects. It is kept in clothes used on special occasions and festivals, and also in cupboard corners as a cockroach repellent.

The smoke of camphor crystal or camphor incense sticks can be used as an environmentally-friendly mosquito repellent. Recent studies have indicated that camphor essential oil can be used as an effective fumigant against red fire ants, as it affects the attacking, climbing, and feeding behavior of major and minor workers. Camphor is also used as an antimicrobial substance. In embalming , camphor oil was one of the ingredients used by ancient Egyptians for mummification.

Solid camphor releases fumes that form a rust -preventative coating and is therefore stored in tool chests to protect tools against rust. In the ancient Arab world, camphor was a common perfume ingredient, according to the Perfume Handbook. In ancient and medieval Europe, camphor was used as an ingredient in sweets. Camphor is commonly applied as a topical medication as a skin cream or ointment to relieve itching from insect bites, minor skin irritation, or joint pain.

Camphor is also used as an aerosol , typically by steam inhalation, to inhibit coughing and relieve upper airway congestion due to the common cold. In high doses, camphor produces symptoms of irritability, disorientation , lethargy , muscle spasms , vomiting , abdominal cramps, convulsions , and seizures. Generally, two grams cause serious toxicity and four grams are potentially lethal. Camphor has limited use in veterinary medicine as a respiratory stimulant for horses.

Camphor has been used in traditional medicine over centuries, probably most commonly as a decongestant. Camphor is widely used in Hindu religious ceremonies. Aarti is performed after setting fire to it usually as the last step of puja. From Wikipedia, the free encyclopedia. Group of stereoisomers. Not to be confused with samphor.
