Hydrogenated Bisphenol A (HBPA), chemically named 4,4' -dihydroxy dicyclohexylmethane, is hydrogenated by Bisphenol A (BPA).
Hydrogenated bisphenol A is a white crystalline powder with low volatility. Its melting point is relatively high, generally around 185-190 ° C, which makes it a solid state at room temperature. In terms of solubility, its solubility in organic solvents varies depending on the polarity of the solvent. Due to the presence of hydroxyl functional groups, hydrogenated bisphenol A has the typical chemical properties of alcohol compounds. It can be esterified with acid to form ester compounds.
Synthesis method:
Hydrogenation reaction: The main synthesis method is the hydrogenation reaction of bisphenol A. Metal catalysts, such as nickel (Ni), palladium (Pd), or platinum (Pt), are commonly used. The reaction is carried out in a hydrogen atmosphere, the reaction temperature is generally between 100-200 ºC, and the pressure is about 1-10MPa. The process of hydrogenation reaction is that bisphenol A molecules are adsorbed on the surface of the catalyst, hydrogen molecules are dissociated into hydrogen atoms, and hydrogen atoms are gradually added to the benzene ring of bisphenol A molecules, and the benzene ring is reduced to cyclohexane ring, and finally hydrogenated bisphenol A is generated.
Process optimization: In industrial production, in order to improve the reaction efficiency and product quality, the reaction conditions need to be optimized. For example, choosing the right solvent can increase the dispersion and reaction rate of the reactants. At the same time, the activity and stability of the catalyst were studied, and the service life of the catalyst was extended and the production cost was reduced by modifying the catalyst or adding auxiliaries.

Application field:
For the synthesis of high performance epoxy resins. Compared with conventional epoxy resin, the epoxy resin synthesized by hydrobisphenol A has better flexibility, weather resistance and yellowing resistance. This epoxy resin is widely used in outdoor coatings, electronic packaging materials and other fields.
In the field of polycarbonate: In the synthesis of polycarbonate, hydrogenated bisphenol A can be used as a copolymer. By reacting with other bisphenol compounds or carbonate compounds, polycarbonate materials with special properties are generated. This polycarbonate material has high transparency, good impact resistance and thermal stability, and can be used in the manufacture of optical lenses, auto parts and other products.
Polyurethane field: Hydrogenated bisphenol A reacts with isocyanate as a polyol component for the synthesis of polyurethane materials. This polyurethane material has good mechanical properties, wear resistance and chemical corrosion resistance. It is widely used in shoe sole materials, elastomer materials and other fields, which can provide comfortable elasticity and long-term durability.
