Hazard Predictions

• Potentially hazardous: May be hazardous but unknown

Although no specific evidence was found for a hazardous reaction between halogenating agents and phenolic salts, strong halogenating agents could potentially halogenate the aromatic ring in phenoxides (Predicted).

In addition, the following evidence was found for hazardous reactions between phenols and strong halogenating agents:

Phenol reacts exothermically with Ca(OCl)2, producing toxic and flammable fumes, which can be ignited by reaction heat (Fawcett, H. 1959. Industrial and Engineering Chemistry Research 51:89A-90A).

Phenol reacts with bromine in aqueous solution at ambient temperatures, producing toxic HCl as a byproduct (Solomons, T.W.G. 1984. Organic Chemistry, 3rd Edition. New York: John Wiley & Sons, Inc. pp. 685).

BrF3 ignites or explodes on contact with most organic compounds (Mellor, J.W. 1941. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Longmans, Green and Co Ltd. Vol. 2, pp. 113; 1956. Volume 2, Supplemental 1. pp. 164-167).
