Definitions

  • the present invention relates to organic bismuth compounds of hydroaromatic endomethylene benzoic acids.
  • Suitable acids of the said kind are the endomethylene-benzoic acid obtainable by oxidation of camphene and similar compounds, for instance, the camphenilanic acid of the formula CH: 011C003 or the acid of the following formula CH.COOH i or the homologous acid of the formula
  • the unsaturated endo-methylene-carboxylic acids obtained as well as the corresponding saturated endo-methylene-carboxylic acids may be transformed into their bismuth salts.
  • the saturated endo-methylene-carboxylic acids are obtainable from the unsaturated acids by bydrogenation.
  • CILCOOE there may also be used endo-methylene-benzoic acids, wherein the endo-methylene-hydrogen atoms have been exchanged for alkyl groups, for instance, the camphane-carboxylic acids of the formula Beilstein, 4th edition, volume9, page 74) are dis-
  • the monoiodo-endomethylene-hexahydromethyl 1" benzoic acid obtainable by addition'of'hydroge'n iodide to the endo-methylene 2.5 'deltas tetra-' hydro-G-methylbenzoic acid, the corresponding diiodo-endtomethylene-hexahydromethyl-benzoic acid obtainable by addition of iodine to the-same parent acid, the mono-iodo-endomethylene-tetrahydromethyl-benzoic acid obtainable 'by-splitei ting off hydrogen iodide from the diiodo-endo methylene-hexahydro
  • the new bismuth compounds can be obtained by causing a bismuth salt to act upon a whollylor partially hydrogenated endo-methylene-benzoic acid.
  • the new bismuth compounds are amorphous substances which decompose without melting when heated, and are insoluble in water, soluble in ether, chloroform and oils and have a strong bactericidal action especially against spirilli, but only a comparatively small toxicity.
  • H P Bi CH: l 011-000- said salt being an amorphous substance, insoluble in water, soluble in ether, chloroform and oils, decomposing without melting when heated and having a strong bactericidal action, especially against spirilli.
  • the bismuth salt of isocamphenilanic acid said salt being an amorphous substance, insoluble in water, soluble in ether, chloroform and oils, decomposing without melting when heated and having a strong bactericidal action, especially against spirilli.
  • said salt being an amorphous substance, in- 15 soluble in water, soluble in ether, chloroform and oils, decomposing without melting when heated and having a strong bactericidal action, especially against spirilli.
