4,4'-Isopropylidenedicyclohexanol Usage And Synthesis

Description

2,2-Bis(4-hydroxycyclohexyl)propane, also known as 4,4'-Isopropylidenedicyclohexanol, is a crystalline, colorless, and odorless compound. The conformation of the cyclohexane rings gives rise to cis-cis, cis-trans and trans-trans isomers. The industrial product is a mixture of these stereoisomers. The physical properties depend on the relative amounts of the isomers present. The trans-trans compound has the lowest energy and is formed from the other isomers at higher temperature. It has the lowest solubility in solvents such as methanol, butanol, and acetone and has the highest melting point of these isomers.

Uses

4,4'-isopropylidenedicyclohexanol is unsaturated polyester resin, epoxy resin raw materials, especially as glass, steel, artificial marble bathtub, plating tank and other components, and has a water resistance, chemical resistance, thermal stability and light stability.

Production Methods

4,4'-Isopropylidenedicyclohexanol is produced by hydrogenation of bisphenol A, 2,2-bis(4-hydroxyphenyl)propane, an industrially important compound made from acetone and phenol (Phenol Derivatives). Bisphenol A is hydrogenated at about 10-30 MPa and at 150-250 ℃ on a nickel, cobalt, or ruthenium catalyst.

Flammability and Explosibility

Non flammable
