in this study, the conditions for producing invert syrup were optimized and factors such as type of acid citric, hydrochloridric and tartaric (each at two levels), reaction time (1 and 1.5 h) and temperature (70 and 80°c) were studied. the properties of invert syrups which produced by different methods were compared with each other and a standard and optimized method, for inversion reaction, wa...

uv/tio2 photocatalysis of chelated copper in aqueous solutions has been performed starting from cu(ii)-tartaric acid, cu(ii)-citric acid, cu(ii)-edta and cu(ii)-dtpa,in the presence of oxygen and at acidic ph. the photocatalytic reaction obeys first-order kinetic equation. the influence of cu(ii) on photocatalytic oxidation of organic ligands and how the various organics will affect the treatmen...

Experiments with azoproteins containing stereo-chemical isomeric groups of d- and l-tartaric acid showed well marked specificity of the anaphylactic reaction to these antigens, in conformity with the results of precipitin tests. Shock in these animals could be prevented by injection of azodye containing the specific groups. This phenomenon is ascribed to a desensitization.

Abstract. The Ti(OiPr)4/tartaric acid diethyl ester/t-BuOOH complex (Sharpless catalyst) was successfully used for the direct asymmetric oxidation of ketones resulting in lactones from cyclobutanones; α,β-dihydroxy ketones from β-hydroxy ketones; alkyl lactone carboxylic acids from 3-alkylcyclopentane-1,2-diones; and spiro-γ-dilactone from 3-(2-hydroxyethyl)cyclopentane1,2-dione in high enantio...

Molecular modelling of an iodine(III) phenoxide was used as a starting point in the design of chiral aryl iodide catalysts for stereoselective oxidative dearomatization reactions. Using this approach, catalysts derived from 8-iodotetralone and tartaric acid were constructed and used to synthesize enantioenriched para-quinols from phenols.
