Abstract

23,575. Heinemann, A. Dec. 4. Benzoic acid; sulphobenzoic acids.-A mixture of benzoic and o- and p-sulphobenzoic acids together with toluene sulphonic acids is obtained by passing ozone, ozonized oxygen, or ozonized air, into a heated mixture of toluene and sulphuric acid; the products are separated in known manner. Sulphobenzoic acids are also obtained by passing ozone, ozonized oxygen, or ozonized air into a heated aqueous solution of a toluene sulphonic acid.
