実験手順

A mixture of (+)-tartaric acid (27 g) and bismuth oxynitrate (8.61 g) in water (50 ml) was heated at 90°-100° with occassional stirring for 30 min, by which time a small portion of the product dissolved completely in weak aqueous ammonia. The mixture was cooled to room temperature then filtered and the filtrate washed well with water until free from water soluble materials. The residue was dried at 70°-80° in vacuo to give the title compound (14.78 g).
