It is employed in fields such as pharmaceuticals, pesticides, high-quality coatings, surfactants, rubber additives, and liquid crystal materials. In response to the needs of national economic development and taking into account the actual conditions of China’s chemical industry, the applications of 1,2-cyclohexanediol are mainly outlined as follows: a) the synthesis of 1,2-cyclohexanediol esters of polyadipic acid and 1,2-cyclohexanediol diglycidyl ethers. A polyurethane material with high hardness, wear resistance, high transparency, and excellent heat resistance was synthesized using 1,2-cyclohexanediol polycaproate as the raw material. b. In alkyd resins, the use of 1,2-cyclohexanediol can increase the surface strength of the coating. It can replace trimethylolpropane and be used in the production of alkyd resins, polyurethanes, unsaturated resins, coatings, high-grade resins (for use in automobiles), and plasticizers. C. Used for the synthesis of catechol.
