Concentrated hydrochloric acid from Fisher Scientic Co. (9.52 ml, 0.1125 mole) was added dropwise, and an immediate temperature rise of 12° C. occurred. The mixture was thereafter heated and the byproduct of the reaction, water, was distilled over at 96° C. and collected. After 2 hours, a 92% yield of antimony (V) hexyl thioglycolate was obtained. The product was filtered to remove unreacted sodium antimonate and the additional byproduct of the reaction, sodium chloride.
