Hypochlorous acid as a reagent for the oxidation of organic compounds in two phase systems - Patent 5068408 (2971 words)
The hypochlorous acid used in the instant process may be characterized as a solution containing from about 5 to about 65, preferably from about 25 to about 60, and most preferably from about 30 to about 50% by weight of hypochlorous acid (HOCl).
While the hypochlorous acid concentration is significantly reduced, the chlorine gas concentration is substantially the same as that in the original gaseous mixture fed to the condenser.
The molar ratio of the hypochlorous acid in the aqueous phase to the organic compound in the organic phase is generally from 0.5 to 1 to about 10 to 1.
eMedicine - Toxicity, Chlorine Gas : Article by Eli Segal, MD (3632 words)
The predominant targets of the acid are the epithelia of the ocular conjunctivae and upper respiratory mucus membranes.
Acids formed by the chlorine gas reaction with the conjunctival mucous membranes are buffered, in part, by the tear film and the proteins present in tears.
Acid burns to the periphery of the cornea and conjunctiva often heal uneventfully, while burns to the center of the cornea may lead to corneal ulcer formation and subsequent scarring.
