[Limiting tests of benzyle halides or heavy alkyles in tensioactive and antimicrobial quaternary ammonium salts].
As working material at the final stage of the synthesis of tensioactive and antimicrobial quaternary ammoniums salts, the alcoyles halides residuums have been let aside. The author developed limiting tests about these impurities particularly on the benzododecinium bromide. Four alternative methods are thus proposed.
