Sodium benzoate Sodium benzoate say again: benzoin acid Sodium. CAS: 532-32-1 the product specification: industry-specific, food grade []] : the former formula C7H5NaO2 molecular weight: 144 [character] : white particles or crystal powder. No smell sweet, acerbity. [usage] : chemical analysis with reagents; Used in medicine industry and plant genetic research
Benzoic acid and called benzoin acid, sodium benzoate and says it benzoin acid sodium. In ordinary temperature benzoic acid soluble in water, in the air (especially hot air in volatile, micro) hygroscopic, about 0.34 g/under normal temperature of 100 ml; But soluble in hot water; Also soluble in alcohol, chloroform and the volatile oil. In use many choose sodium benzoate; Benzoic acid and sodium benzoate of traits and anti-corrosion properties are similar. Sodium benzoate mostly for the white particles, odourless or microstrip rest scent smell and taste sweet, convergence; Soluble in water (room temperature) 53.0 g / 100 ml or so, PH in 8 or so; Sodium benzoate is also in alkaline medium acidic preservatives, no sterilization, bacteriostatic action; Its anticorrosion best PH is 2.5 4.0, when 5% of the solution in PH5.0 bactericidal effect also is not very good. Sodium benzoate lipophilic bigger, easy to penetrate cell membrane into the cells in the body of the cell membrane permeability, interference, restrain the cell membrane of amino acid absorption; To enter the cell ionization acidification inside the cell in the body, and control the storage cell activity of enzyme is breathing, stop acetyl coa A condensation reaction, thus plays food antiseptic purpose
