Abstract

A long-chain alkyl quaternary ammonium compound, i.e. a compound containing a quaternary ammonium grouping and an alkyl radical containing not less than 6 carbon atoms, or a solution of such a compound in hydrochloric or sulphuric acid is added to sulphuric acid to inhibit its action on metals. Substances referred to are octadecyl-, dodecyl-, and cetylpyridinium bromides, and cetyl- and octadecyltrimethylammonium bromides.ALSO:A long chain alkyl quaternary ammonium compound, i.e. a compound containing a quaternary ammonium grouping and an alkyl radical containing not less than 6 carbon atoms, or a solution of such a compound in hydrochloric or sulphuric acid is added to acid pickling baths as an inhibitor. Substances referred to are octadecyl-, dodecyl-, and cetylpyridinium bromides, and cetyl- and octadecyltrimethylammonium bromides.
