Description

Tungstic acid is a solid acidic oxide that is used as an oxidation catalyst for organic reactions. Tungstic acid can also be used in the production of p-hydroxybenzoic acid, which is an intermediate in the synthesis of vitamin C. Tungsten has been shown to catalyze the reaction between hydrogen fluoride and water vapor with a molar ratio of 1:2 to produce hydrogen tungstate. The reaction mechanism is thought to involve intermolecular hydrogen bonding that leads to the formation of particles at high temperatures and a phase transition temperature of about 500°C. Tungsten has good chemical stability in air and does not decompose or react with many substances.
