Types of Camphor

Below are the different types of camphor

Natural camphor – It is obtained naturally from plants that produce camphor, particularly Cinamommum camphora. It has been marketed for many years as a forest product.

Synthetic camphor – It is derived from turpentine oil, specifically from the alpha-pinene found in coniferous tree oils. Acetic acid is used as a solvent and strong acid as a catalyst to convert alpha-pinene into isobornyl acetate. Hydrolysis of isobornyl acetate yields isoborneol, which is then oxidized to produce racemic camphor.

Production of Camphor

A biosynthetic method can be used to produce camphor using geranyl pyrophosphate. Geranyl pyrophosphate is converted to linaloyl pyrophosphate, which is further converted to bornyl pyrophosphate. Bornyl pyrophosphate is then hydrolyzed into borneol, which is then oxidized to form camphor.

Through the mevalonic acid pathway, geranyl pyrophosphate is converted to bornyl pyrophosphate. The reaction occurs in cells, so the reaction conditions are not well defined, but the enzyme bornyl diphosphate synthase is required to convert geranyl pyrophosphate to bornyl pyrophosphate. A series of steps are then followed by the oxidation of borneol or isoborneol into camphor to convert bornyl pyrophosphate into camphor enzymatically.

In order to produce camphor via chemical synthesis, borneol or isoborneol must undergo oxidation. This process involves dissolving the borneol in a mixture of acetone and ethanol, which is then acidified with chromic acid in sulphuric acid. The resulting solution is heated and refluxed for several hours to initiate the reaction. After cooling, any excess acid is removed using reducing agents. Finally, the isolated camphor can be obtained by dissolving it in non-polar solvents and evaporating the solvents.

Uses of Camphor

It is an important ingredient of many creams or rubs whose aim is to reduce pain caused by insect bites, cold sores, minor burns, etc.
It helps reduce fungal infections.
It is sometimes used as a food additive to enhance the flavor of the food.
It is used for some religious purposes.
Camphor is used to reduce pains caused by arthritis.
Camphor can be used as a cough suppressant.
Camphor can be used as a muscle rub to reduce muscle cramps.

Health Hazards of Camphor

When Camphor comes in direct contact with the eyes it causes irritation.
Inhaling of camphor acid can cause irritation in the nose and throat which leads to a cough.
Continues Exposure to a high quantity of camphor causes Unconsciousness or even death.
High Exposure to camphor may cause Kidney damage and has adverse effects on the nervous system.
