Forty percent HCl is known as “fuming” hydrochloric acid because of its extremely high evaporation rate. Hydrochloric Acid HCl Molar Mass, Molecular Weight. Its melting point is -114.22 ̊C (-173.596 ̊F), boiling point -85.05 ̊C (-121.09 ̊F). 58 / Monday, March 26, 2012 / Rules and Regulations 10/24/2017 EN (English US) 6/8 Hydrochloric Acid, 37% w/w (7647 -01 -0) Persistence and degradability Biodegradability: not applicable. LOT 84L Potassium acid phthalate: Vapor Pressure: 5.7mmHg at 0°C: NIST: Traceable to NIST. 77, No. Hydrochloric Acid, 31 – 36%. HCl is a colorless gas at room temperature. should display a high boiling point relative to the components of the feed acid, and should, finally, lead to an economic separation with respect to energy consumption Sulfuric acid and concentrated aqueous solutions of metal chlorides, such as MgCl 2 and CaCl 2 are for example appropriate extraction agents for the concentrationing of hydrochloric acid.
