Chemical Propertieswhite crystals or powder with a pungent odour
Chemical PropertiesThymol occurs as colorless or often large translucent crystals, or as a white crystalline powder with a herbal odor (aromatic and thymelike) and a pungent caustic taste.
Chemical PropertiesThymol is the main constituent of thyme and some origanum oils; it also occurs in many other essential oils. It forms colorless crystals (mp 51.5°C) with a spicy, herbal, slightly medicinal odor reminiscent of thyme. It is prepared on a technical scale in a continuous high-temperature, high-pressure, liquid-phase, ortho-alkylation process, fromm-cresol and propylene, in the presence of activated aluminumoxide hydrate.
The crude thymol mixture, consisting of approximately 60% thymol, unreacted m-cresol (about 25%), and other (iso)propyl-substituted products, is separated by fractional distillation. Most of the by-products are recycled.
Thymol is used as a dry top note in lavender compositions, in men’s fragrances, and as a disinfectant in oral care products. It is also important as a startingmaterial for the production of racemic menthol.
Anethole is used in large quantities in the alcoholic beverage industry and in oral hygiene products. Some crude anethole is converted into anisaldehyde.
Chemical PropertiesIt has a characteristic herbaceous, warm and aromatic odor with a sweet, medicinal, spicy flavor
describeThere are two main sources of thymol: one is extracted from natural products (thyme oil, oregano oil, basil oil), and the other is synthetically obtained. Due to the limited natural resources, high extraction cost and high environmental pressure, synthetic thymol is currently the mainstay.
UsesThymol is an antimicrobial compound which can increase the efficacy of antibiotics involving drug resistant bacteria. It inhibits growth and lactate production as well as reduces cellular glucose upta ke within the bacteria.
Thymol used as analytical reagents and preservatives for the preparation of spices, drugs and indicators, etc., and also commonly used in the treatment of skin mycosis and ringworm.
GB2760-1996 stipulates that it is temporarily allowed to use edible spices. It is mainly used to prepare flavors such as cough drops, gum candy, peppermint, citrus, mushrooms and spices.
Determination of ammonia, antimony, arsenic, titanium, nitrates and nitrites; determination of ammonia, titanium and sulfates; fragrances; preservatives; insect repellants.
Production MethodsIt is obtained from the volatile oil of thyme (Thymus vulgaris Linne′ (Fam. Labiatae)) by fractional distillation followed by extraction and recrystallization. Thyme oil yields about 20–30% it. It may also be produced synthetically from pcymene, menthone, or piperitone, or by the interaction of m-cresol with isopropyl chloride.
