Applications:
Benzoic acid is a mono-functional, romatic acid, which is widely used as a building block for the synthesis of alkyd resins. It is also used as a preservative in many industrial applications, such as antimicrobial agent of latex, toothpaste, jam, dyeing and printing mordant, pharmaceutical and dye intermediates for preparing plasticizer, spices and the like, rust inhibitor of steel equipment and so on.
