Benzoic acid can also be used to improve the gloss, viscosity, strength and chemical resistance of various alkyd resin coatings. Benzoates and benzoic acid can stop the chain growth of alkyd resin polymers and promote the crystallinity of the product [7]. The introduction of benzoic acid into the alkyd resin allows the film to dry quickly, but it is not as insolvent as styrene. The gloss, hardness and water resistance of the paint film made by the modified alkyd resin are improved.
Benzoic acid can be used as an intermediate in the production of benzoate and phthalate, which are important plasticizers. Bromobenzoic acid can be produced by bromobenzoic acid reaction, and m-bromobenzoic acid can be used as a binder for photographic materials. [1
