Purity Classification & Impurity Control Standard
We classify hydrogen chloride gas into multiple grades according to different usage scenarios to meet diversified procurement demands:
1. 99% Industrial Grade
Cost-effective conventional grade, mainly used in basic chemical raw material preparation, general pickling treatment and ordinary chemical synthesis, suitable for large-scale low-demand industrial production.
2. 99.99% High Purity Grade
Medium high purity product, strictly control internal moisture, nitrogen, carbon dioxide and other impurities, widely used in fine chemical reaction, pesticide raw material synthesis and intermediate production.
3. 99.995% Premium High Purity Grade
Semi-electronic high standard grade, lower impurity content, stable gas performance, preferred material for high-precision chemical experiment and new material research and development.
4. 99.9999% Ultra High Purity Electronic Grade
Top-level high-purity HCl gas, after deep removal of all trace impurities, ultra-low moisture and metal ion content, fully meet the strict requirements of semiconductor wafer etching, chip manufacturing, electronic material growth and other high-end precision processes.
Physical and Chemical Properties
Anhydrous hydrogen chloride gas is extremely easy to absorb moisture in the air, it will quickly combine with water vapor to form hydrochloric acid mist, showing obvious white smoke phenomenon. It has extremely high solubility in water, and the aqueous solution is strong corrosive hydrochloric acid. Under dry sealed storage environment, the gas has stable chemical properties, not easy to deteriorate. It is easy to react with most active metals, so special anti-corrosion cylinders and pipeline materials must be used in storage and use. It has good solubility in various organic solvents, and is often used as acidic catalyst and chlorinating agent in organic synthesis reaction.
