Perchloric Acid

Overview

Perchloric Acid is a strong mineral acid with the CAS number 7601-90-3 and EC number 231-512-4. Supplied by SoleChem Chemicals, it is a highly reactive chemical used in analytical chemistry, explosives manufacturing, and other specialized industrial applications.

Physical and Chemical Properties

• Chemical Formula: HClO4

• Appearance: Colorless, odorless liquid (aqueous solution)

• Molecular Weight: 100.46 g/mol

• Density: ~1.67 g/cm³ (70% solution)

• Solubility: Miscible with water, forms azeotropic mixtures

• pH: Strongly acidic (<1 in dilute solutions)

Production Method

Perchloric Acid is produced by reacting sodium perchlorate or barium perchlorate with sulfuric acid, followed by distillation to yield a concentrated aqueous solution. The process requires strict control to ensure purity and safety due to the acid’s highly reactive nature.

Industrial Applications

• Analytical Chemistry: Used as a strong oxidizing agent in titrations and sample digestions.

• Explosives: Employed in the production of perchlorate salts for pyrotechnics and rocket propellants.

• Chemical Synthesis: Acts as a catalyst or reagent in organic and inorganic synthesis.

• Electroplating: Utilized in metal surface treatments for its strong acidic properties.

Safety Information

• Handling: Use acid-resistant gloves, goggles, and protective clothing. Work in a fume hood due to corrosive fumes.

• Storage: Store in glass or compatible containers in a cool, ventilated area, away from organic materials and reducing agents.

• Hazards: Highly corrosive and oxidizing. Can cause severe burns and fires upon contact with organic materials. Harmful if inhaled or ingested.

• First Aid: Rinse skin or eyes immediately with large amounts of water for at least 15 minutes. Seek immediate medical attention.
