Basic Properties of o-tert-Butyl Cyclohexanol

o-tert-Butylcyclohexanol (2-tert-Butylcyclohexanol) is an organic compound with the formula C10H20O. It is an alcohol compound with a cyclohexane ring and a t-butyl substituent. The cyclohexane ring in its molecular structure provides stability, while the t-butyl substituent increases the hydrophobicity of its molecule. The compound generally appears as a colorless to pale yellow liquid with a high boiling point and low water solubility. At room temperature, its physical and chemical properties are relatively stable, but decomposition or reaction may occur under high temperature or strong acid-base conditions.

o-tert-butyl cyclohexanol use

Ortho-tert-butyl cyclohexanol has a wide range of applications in many industries. It is used as a fragrance and fixative in cosmetics and personal care products because of its ability to provide a unique aroma and extend the longevity of other fragrances. The compound is also used in the field of medicine as an intermediate for the synthesis of various drugs and active ingredients. In agricultural chemicals, it can be used as a solvent or intermediate for pesticides and herbicides. In industry, o-tert-butylcyclohexanol is also used in the manufacture of polymers, resins and coatings, as it can improve the performance and stability of these materials.

Ortho-tert-butyl cyclohexanol upstream and downstream raw materials

In the production of o-t-butyl cyclohexanol, the upstream feedstock mainly comprises cyclohexane and isobutylene. Cyclohexane can be obtained by petroleum refining processes, while isobutene is usually produced by cracking petroleum gas or by dehydrogenation of isobutane. In the production process, cyclohexane is first oxidized to produce cyclohexanone, and then electrophilic addition reaction with isobutylene in the presence of acidic catalyst to produce o-t-butyl cyclohexanol. Downstream products, on the other hand, include the aforementioned various chemicals and end-use consumer goods, which have important applications in a number of industries.

o-tert-Butyl Cyclohexanol Production Process

The production process of o-t-butylcyclohexanol generally involves the oxidation of cyclohexane, the formation of cyclohexanone and the t-butylation reaction. Cyclohexane is first converted to cyclohexanone by the action of an oxidizing agent such as air or oxygen. Subsequently, cyclohexanone is reacted with isobutylene under the catalysis of an acidic catalyst such as sulfuric acid or phosphoric acid to produce o-t-butylcyclohexanol. The entire production process requires strict control of reaction conditions to ensure high yield and high purity, as well as effective treatment of by-products and waste materials to reduce environmental pollution.

o-tert-Butyl Cyclohexanol Storage Method

Since o-tert-butylcyclohexanol has flammability and certain toxicity, its storage method requires special attention. It should be stored in a cool, ventilated and dry place, away from direct sunlight and high temperature. The storage area should be away from fire, heat and strong oxidizers. The storage container shall be made of fire-proof and explosion-proof materials and well sealed to prevent leakage. Operators should wear appropriate protective equipment, such as gloves and goggles, when handling the compound to avoid direct contact or inhalation of vapors.

o-tert-Butyl Cyclohexanol: Safety and Environmental Protection

Safety and environmental protection are important considerations in the use and disposal of o-t-butylcyclohexanol. The compound is irritating to the skin and eyes, and inhalation of its vapors may affect the respiratory system. Therefore, operators need to receive professional training and take protective measures during operation. Waste disposal shall comply with local environmental protection regulations to avoid environmental pollution caused by random discharge. Production enterprises should also establish a sound emergency plan to deal with possible leakage or fire accidents.

o-tert-Butyl Cyclohexanol Market Prospects

With the continuous development of the cosmetic, pharmaceutical and agricultural chemicals industries, the market demand for o-tert-butyl cyclohexanol is expected to continue to grow. Consumer demand for high quality products, especially in the personal care and medical fields, has driven the use of this compound. Technological advances and improvements in production processes will also further improve its production efficiency and product quality. Overall, o-tert-butyl cyclohexanol has a good market prospect in the next few years.

Conclusion

As an important organic compound, o-tert-butyl cyclohexanol plays an important role in many industries due to its unique physical and chemical properties and wide range of uses. By optimizing the production process and strictly controlling the storage conditions, the production efficiency and use safety can be effectively improved. With the growth of market demand and technological progress, o-tert-butyl cyclohexanol is expected to achieve wider application and larger market share in the future.
