Sodium Bnezoate is a white crystalline grain or powder.
It is widely used for food preservative produced by reaction from sodium hydroxide with benzoic acid. Sodium Benzoate is a better molds and yeasts inhibitor and since acidity foods grow bacteria, mold and yeast quickly, it is cheapest way to preserve them.
Potassium benzoate widely used as food additives and preservatives. its appearance is powder or crystal powder. it is Odorless or almost odorless, soluble in water and ethanol. Purity is more than 99%. the potassium benzoate formula is C7H5KO2, Molecular weight is 160.2
Application:
Commonly used as food preservative.
Raw material in the production of pesticide, dye, medicine, perfume, mordant, plasticizer.
Modifying agent for polyamide resin and alkyd resins.
Rust inhibitor of steel equipment and so on.
