Abstract

Piezoelectric compounds produce an electric charge in response to applied mechanical stress. Ferroelectric compounds, a subset of piezoelectrics, possess a spontaneous electric polarization that can be reversed under the application of an external electric field. The goal of this research is to synthesize croconic acid and its barium, sodium and potassium salts. From these materials, new croconate salts will be prepared and single crystals of these compounds will be grown in order to explore their potential piezoelectric or ferroelectric properties. Initially, the disodium salt of tetrahydroxy-p-benzoquinone was prepared from glyoxal. Once prepared, this disodium salt was then oxidized and decarboxylated to provide barium croconate, which was acidified to afford croconic acid. Moreover, through a metal ion exchange, barium croconate was converted to either sodium or potassium croconate. Croconic acid has was synthesized with an average percent yield of 33.72 %, while sodium, potassium and barium croconate were synthesized with average percent yields of 58.97%, 56.26%, and 78.78% respectively.
