A flow injection manifold is proposed for the sequential determination of titratable (total) acidity based on a pseudotitration and of tartaric acid based on the formation of a coloured vanadate complex. The method involves in-line dialysis prior to injection to avoid interference from the sample background absorption in the spectrophotometric detection. The changes in the colour of both reacti...

A multicommuted flow system with the propulsion device placed before detection is proposed for the determination of tartaric acid and free potassium in table and Port wines. A dialysis unit was introduced to increase sample dilution and minimize matrix interferences. The determination of tartaric acid was based on the spectrophotometric monitorization of the complex formed by the dialyzed analy...

A one-pot synthesis of (S)-(-)-propranolol is reported. Zn(NO3)2/(+)-tartaric acid catalyzed enantioselective synthesis of (S)-(-)-propranolol via kinetic resolution of key intermediate ?-naphthyl glycidyl ether with high optical and chemical yield.

the purpose of this study was to determine the therapeutic efficacy of citric and tartaric acids on experimental dermatophytosis in guinea pigs. in this study, the susceptibility of trichophyton mentagrophytes var. mentagrophytes to citric and tartaric acids was assessed using the macrodilution broth method. in the animal experiments, a cream consisting of the mixed acids was topically applied ...

powdery mildew caused by erysiphe necator schw. is one of the most economically destructive diseases of grapevines all over the world including iran. in this experiment, the effects of powdery mildew on grape yield, sugar and tartaric acid contents of must quality were quantified for different grapes with 14 cultivars of grapes including shahani, kishmishi, rasmi, tokolgan, garashilig, seyrakpo...
