Vicinal H—H and C—H coupling constants are reported for (+)-tartaric acid and meso-tartaric acid at various pH values and used in a discussion of the conformation of these molecules. This is found not to change much with pH. For the meso form, in particular, the most favoured conformer is determined not so much by the possibility of internai [Formula: see text] hydrogen bonding but, at least in part, by stabilization of polar conformations in a sol vent (H2O) of high dielectric constant.

AbstractTreatment of [Mo2S2O2(H2O)6]2+ with racemic tartaric acid (tartH4) in the presence of sodium hydroxide and cesium chloride in aqueous solution led to the isolation of a new tetra-molybdenum ring cluster Cs4[Mo2O2(μ-S)2]2(μ4-tart)2. The cyclic cluster polyanion consists of two dinuclear [Mo2O2(μ-S)2]2+ moieties and two bridging tart4− ligands. The cyclic polyoxothiomolybdate cluster, supported on the mesoporous silica SBA-15, was tested for heterogenerous catalysis in thiophene hydrodesulfurization.

Extraction equilibria in the system aqueous solution of D-tartaric acid-solution of tertiary amine in diluent at 25 °C have been studied. The amine was Alamine 336, a long-chain tertiary amine with C8-C10 alkyls in 2 : 1 ratio; the diluent was chelating extractant LIX 54, a solution of an alkyl β-diketone in kerosene. The experimental results were correlated using a mathematical model which takes into account chemical reactions involved in acid-amine complex formation and non-specific effects of the nonideality of the system.
