C00336 - SEMI C3.36 - Standard for Hydrogen Chloride (HCl), 99.994% Quality (Provisional)

This Standard was technically approved by the Gases Global Technical Committee. Available at www.semi.org in July 2001; originally published in 1989; previously published in 1994. 　 NOTICE: This Document was balloted and approved for withdrawal in 2001. 　 Hydrogen chloride is a colorless, pungent, corrosive gas having a suffocating odor. Hydrogen chloride is heavier than air and fumes strongly in moist air. It is very soluble in water and alcohol, and also soluble in ether. Hydrogen chloride is shipped as a liquefied compressed gas stored under its own vapor pressure. As long as liquid is present in the cylinder, the pressure will remain fairly constant. When the liquid phase is exhausted, the cylinder pressure will drop rather rapidly. 　Referenced SEMI StandardsNone.
