3-Hydroxybenzoic acid Usage And Synthesis

Chemical Properties

white to light yellow crystal powder

Uses

Intermediate for plasticizers, resins, light stabiliziers, petroleum additives, pharmaceuticals.

Uses

m- Hydroxybenzoic acid is reported as an intermediate in the manufacture of germicides, preservatives, pharmaceuticals, and plasticizer.

Definition

ChEBI: A monohydroxybenzoic acid that is benzoic acid substituted by a hydroxy group at position 3. It has been isolated from Taxus baccata.

Reactions

m-Hydroxybenzoic Acid, of the three hydroxybenzoic acids, the metaisomer is of least commercial importance. Unlike salicylic acid, m-hydroxybenzoic acid does not undergo the Friedel-Crafts reaction. It can be converted in 80% yield to m-aminophenol by the Schmidt reaction, which involves treating the acid with hydrazoic acid in trichloroethylene in the presence of sulfuric acid at 40 °C.

Purification Methods

Crystallise the hydroxyacid from absolute EtOH. [Beilstein 10 IV 315.]
