Benzoic acidor benzene-carbonic-acid is a monobasic aromatic acid, moderately strong, white crystalline powder, very soluble in alcohol, ether, and benzene, but poorly soluble in water (0.3g of benzoic acid in 100g of water at 20°C). Benzoic acid has the advantage that it does not affect...

both the pH value and the volume ratio of the flowed acid and alkali solution at each titration point can be obtained simultaneously from the two electrodes,and then the concentration of each component in the mixture can be obtained from the titration curves by multivariate calibration method.The...
Isomeric free radicals formed by Mu adding to o/m/p positions of benzoic acid in water were detected by LCR and the corresponding resonance positions and proton hyperfine coupling constants were obtained. There was an isotope effect of the 'second kind' for these Mu-radicals in the range of ...
As benzoic acid itself is only slightly soluble in water, sodium benzoate - which, under acid conditions, converts to undissociated benzoic acid - is often used instead.关键词: benzoic acid sodium benzoate food safety detection of benzoic acid ...
