Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa)Infobox references 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. The equation for this synthesis is:
- 2 C6H5OH + CH3C(O)CH2CH2COOH → CH3C(p-C6H4OH)2CH2CH2COOH + H2O
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.[1]
