hydrogen chloride  

CAS 7647-01-0

HS code  28061000

Hydrogen chloride is a colorless gas with a pungent odor, which is highly irritating to the upper respiratory tract and corrosive to eyes, skin and mucous membranes. 

Specification:

Hydrogen Chloride, HCL Specialty Gas
The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.

Product packaging:
Hydrogen chloride gas is strongly irritating, non-combustible gas, and strongly corrosive when dissolved in water. The product is packaged in a high-pressure special steel bottle and is in a liquid state. The special steel bottle is a seamless steel gas cylinder, and the bottle is polished. The bottle valve is a corrosion-resistant stainless steel diaphragm valve. The design pressure of the cylinder is 12.5Mpa, and the working pressure is about 5-6Mpa.

Requirements for transportation and loading
1. When transporting, loading and unloading hydrogen chloride steel cylinders, you must wear a bottle cap, handle it lightly, and do not throw, slip, roll, or bump;
2. For customers who bring their own special car to pull the goods, the cylinders should be placed flat in the car, the mouth of the bottles should be in the same direction, and properly fixed. Chemical transportation qualified units and signed agreements to ensure the safe transportation of steel cylinders.

Application
Packaged hydrogen chloride (HCl) is used in a range of industries and applications including:
Chemicals: To promote and regenerate catalysts in the petrochemical industry and to add viscosity to oils.
Also used for hydrochlorinations, e.g. production of methyl chloride, oxichlorinations and vinyl chloride.
Hydrogen chloride is also used to produce sulfuric chlorohydrins, synthetic rubbers, etc.
Electronics: High purity gas is widely used in the electronics industry. It is a chlorine carrier produced by high temperature cracking.
Applications: scouring furnaces (quartz chambers), dissolved in water as an aqueous cleaning agent to prepare metal surfaces for electro plating, selective etching of windows in electronic microcircuits and carrier for non-volatile elements in the form of gaseous chloride.
Food & Beverages: To remove the remaining fibres from cotton seeds after the cotton wool has been separated and before the seed is stored for re-sowing next season and also to separate cotton from wood.
Steel & Metals: Used in the production of hard metal.
Pharma & Biotechnology: Used in pharmaceutical synthesis.
1.Electronic grade usage: It is mainly used for gas phase polishing, epitaxial base corrosion and carbide manufacturing of single crystal silicon in semiconductor device production.
2.Chemical grade usage: Pharmaceutical intermediates, food and feed additives, chemical reagents and film developers and other fine chemicals manufacturing industry.
3.Industrial grade usage: Synthesis of pesticide intermediates, feed additives, chemical reagents and other fine chemicals
