To use:

As a preservative of food, medicine, cosmetics, toothpaste, spices, tobacco and feed, Benzoic acid has the function of sterilization and inhibition of bacterial growth. The change of PH value has a great influence on its effect, the effect is the best when the PH value is 2.5-4.5, and the effect is obviously reduced in the alkaline medium. It is widely used as a preservative in food, medicine, cosmetics, toothpaste, spices, tobacco and feed.

Improving the gloss, viscosity, strength and chemical corrosion resistance of alkyd resin coatings can stop the chain growth of alkyd resin and change the crystallinity of products.

Hydrophobic polyester fiber color can be used as a carrier of dyes.

Synthesis of benzoyl chloride, as well as a variety of plasticizers and other raw materials.
