Cyclohexanedimethanol is an important chemical raw material, which is widely used in the production of plastics, fibers, coatings, adhesives and other fields. It has excellent chemical stability and thermal stability, and can react with various chemical substances to generate a variety of useful compounds. The physical properties of

cyclohexanedimethanol include colorless transparent liquid with a light sweet taste, a relative density of about 1.06, a boiling point of 245 ℃, a melting point of 25.5 ℃, a refractive index of 1.4958, and a flash point of 124 ℃. It is insoluble in water, but can be miscible with alcohol, ether, acetone, benzene and other organic solvents.

In the production process, cyclohexanedimethanol can be synthesized by a variety of methods, the most commonly used of which is the cyclohexanone method. The method uses cyclohexanone as raw material to obtain cyclohexanedimethanol through catalytic hydrogenation reaction. In addition, other synthesis methods such as a cyclohexanediol method may also be employed. The main use of

cyclohexanedimethanol is as an important raw material for the production of polyurethane foam. It can react with isocyanate to produce polyurethane foam, which has excellent thermal insulation, sound insulation, earthquake resistance and other properties, and is widely used in construction, home appliances, automobiles and other fields. In addition, cyclohexanedimethanol can also be used to produce unsaturated polyester resins, coatings, adhesives, etc.

in the use of cyclohexanedimethanol, need to pay attention to its toxicity and safety precautions. Cyclohexanedimethanol is a low-toxic chemical, but it has a certain stimulating effect on the eyes, skin and respiratory system of the human body. Therefore, in the process of production and use, it is necessary to take corresponding protective measures, such as wearing protective glasses, gloves and other personal protective equipment, as well as maintaining good ventilation and other environmental measures.

In conclusion, cyclohexanedimethanol is an important chemical raw material and has a wide range of applications in the field of chemical production raw materials.
