Overview
Hexachloroethane (HCE) is a chlorinated hydrocarbon widely used in various industrial and chemical applications. Its high chlorine content, stability, and reactivity make it a valuable intermediate and additive in multiple fields, including metallurgy, agriculture, pharmaceuticals, and rubber processing.

Applications

• Solvent and chemical intermediate: Used as a solvent and raw material for the production of fluorine-113, pesticides, pharmaceuticals, and veterinary drugs.

• Smoke generators: When mixed proportionally with zinc powder, ammonium chloride, and ammonium perchlorate, HCE forms effective smoke‑producing compositions for military and signaling applications.

• Metallurgy: Acts as a degassing and deoxidizing agent for aluminum, magnesium, copper, and their alloys, removing hydrogen and oxides to improve metal quality.

• Rubber industry: Used as a substitute for camphor in celluloid and as a vulcanization accelerator.

• PVC processing: Employed as a plasticizer additive and in lubricant formulations.

• Veterinary medicine: HCE itself serves as an insecticide and anthelmintic, primarily used in treating liver and stomach diseases in ruminants, as well as schistosomiasis and nematode infections.

• Foam suppression: Used as a defoaming agent and degassing agent in various industrial processes.

Key Properties

• High chemical stability under normal conditions.

• Low solubility in water, but readily dissolves in organic solvents.

• Sublimes at moderate temperatures, making it suitable for smoke generation.

• Toxic and should be handled with appropriate safety measures.

Handling and Storage

• Store in a cool, dry, well-ventilated area, away from strong oxidizers and reducing agents.

• Keep containers tightly sealed to prevent contamination and moisture absorption.

• Use appropriate personal protective equipment (gloves, safety goggles, respirator) when handling.

• Avoid inhalation of dust and contact with skin and eyes.
