Definitions

  • the cleaning and pickling acids with which my invention is especially useful are those non-oxidizing mineral acids from the class which consists of sulphuric, phosphoric, hydrochloric, r ilfamic, hydroll ub'fic and fluosll sisa
  • My invention resides in the discovery that the addition of a small amount of triphenyl sulfonium chloride to an slsanias 9 1PiFEQPQQhlE QEPfgl iglfi describsd substantialj prevents or retards the attack of the acid on the Basis metalwithoutinterfefing with theremovahof scale or x15513651 the surface? carrying out my invention the baths are normally used at conventional concentrations of acid and at customary temperatures. These factors, therefore, are familiar to the art and can be varied as desired within the practices which are customary in this field.
  • triphenyl sulfonium chloride which I incorporate in such baths can vary but should, of course, be suflicieut to substantially reduce the rate of acid attack on the basis metal while still accomplishing the "desired 'cleaning and pickling.
  • triphenyl sulfonium chloride is required and my experience indicates that this need be np greater than approximately 1% by weight of the bath, although this limit may be exceeded to a reasonable extent without, apparently, in any way impairing the desired results.
  • a useful amount for any particular acid or type of work can easily be determined by simple test within the knowledge of those skilled in this art.
  • Still another example involved steel panels certain of which were immersed in a 75% phosphoric acid pickling solution containing 1% triphenyl sulfonium chloride. The bath was employed at 45 C., and the panels lost only 1.17 grams per square foot after 24 hours immersion, whereas, similar panels pickled in a similar but uninhibited phosphoric acid solution lost 209 grams per square foot after only 17.5 hours of immersion.
  • cleaning and pickling of metals according to my invention can be carried out with any of the procedures familiar in this art as by continuously passing the metal to be pickled (such as wire or sheets) through a nhmber of baths in a regulated manner or by immersing the articles in the bath for a suitable period of time.
  • the temperature may be varied as indicated above, but ordinarily the baths of my invention are used at temperatures of from to F.
  • a mineral acid bath for cleaning and pickling metal surfaces said bath containing, as an inhibiting addition agent, an amount of triphenyl sulfonium chloride which is sufficient to reduce the rate of acid attack on metal.
  • An acid bath for cleaning and pickling metal surfaces comprising acid from the class consisting of sulphuric, phosphoric, hydrochloric, sulfamic, hydrofluoric and fluosilicic acids and including triphenyl sulfonium chloride in an amount sufiicient to reduce the rate of attack of the acid on the metal.
