Carboxylic acids react with SOCl2 to form highly reactive acyl halides, toxic SO2 gas, and corrosive HCl gas (Weil, E. D., Sandler, S. R. and Gernon, M. 2006. Sulfur Compounds. Kirk-Othmer Encyclopedia of Chemical Technology (Online)).
Acetyl chloride reacts violently with acids (Pohanish, Richard P.; Greene, Stanley A. (2009). Wiley Guide to Chemical Incompatibilities (3rd Edition). John Wiley & Sons. p. 20).
Acids are often found as aqueous solutions, and the water presents a significant hazard. Acyl halides react vigorously with water in an exothermic reaction producing HX gas (Pohanish, Richard P.; Greene, Stanley A. (2009). Wiley Guide to Chemical Incompatibilities (3rd Edition). John Wiley & Sons. p. 20).
Potential Gas Byproducts
- Hydrogen Halide (HX)
