Synthesis of bismuth (III) oxofumarate and its solubility in organic solvents

Abstract

This paper present the synthesis of bismuth (III) oxofumarate (BiO) 2 C 4 H 2 O 4 by solution-solid reaction due to the interaction of basic bismuth nitrates [Bi 6 O 5 (OH) 3 ](NO 3 ) 5 ·3H 2 O and [Bi 6 O 4 (OH) 4 ](NO 3 ) 6 ·H 2 O with aqueous solutions of fumaric acid C 4 H 4 O 4 . Solubility of (BiO) 2 C 4 H 2 O 4 in various organic solvents has been investigated. The morphology and phase composition of the samples was established by X-ray diffraction, scanning electron microscopy, thermogravimetric and chemical analyzes.
