Description

Diphenolic acid is a carboxylic acid with molecular formula C17H18O4. Its IUPAC name is 4,4-bis(p-hydroxyphenyl)pentanoic acid, and it can be prepared by the condensation reaction of phenol with levulinic acid in the presence of hydrochloric acid. Diphenolic acid is a solid at room temperature, melting at 168–171°C and boiling at 507°C. According to its MSDS, diphenolic acid is soluble in ethanol, isopropanol, acetone, acetic acid, and methyl ethyl ketone, but insoluble in benzene, carbon tetrachloride, and xylene.
Diphenolic acid may be a suitable replacement for bisphenol A as a plasticizer.
Diphenolate esters have been used to synthesize epoxy resins as a replacement for the digylcidyl ether of bisphenol A.The digylcidyl ethers of n-alkyl diphenolate esters have similar thermomechanical properties to the digylcidyl ether of bisphenol A when cured, but the viscosity and glass transition temperature vary as a function of the ester length. Diphenolate esters have also been used to synthesize polycarbonates with a potential for water solubility.
