Abstract

In this research, croconic acid and its barium and sodium salts croconate were synthesized from glyoxal. Glyoxal was converted to the disodium salt of tetrahydroxy-p-benzoquinone. This disodium salt was then converted to barium croconate, and barium croconate was in turn converted to either sodium croconate or croconic acid. Croconic acid was prepared with an overall yield of 14.3% from glyoxal. Barium croconate was prepared from the disodium salt of tetrahydroxy-p-benzoquinone in 65.7% yield and sodium croconate was prepared from barium croconate in 28.9% yield. The yields of the croconic acid as well as its salts were similar to the reported literature values. Based upon the experience of this laboratory, this procedure has proven to be the most reliable method for the preparation of croconic acid and its salts. These materials will be used to produce other salts of croconic acid. Once prepared, single crystals of these salts will be grown, and the potential ferroelectric and piezoelectric properties of these salts will be determined.
