    摘要: In the degradation of organic compounds in an effluent by oxidizing the effluent at an elevated temperature with oxygen, the improvement which comprises effecting the oxidation at a redox potential of from about 300 to 600 millivolts, as measured with a platinum electrode against a silver-silver chloride electrode, at a temperature of from about 80.degree. to 250.degree. C and under a pressure of from about 30 to 200 bars. The redox potential may be maintained by an Fe.sup.2+ and/or Fe.sup.3+ ion system and the pH is advantageously below about 7.

    摘要: New diaminoalkyldiphenyl ethers of the formula ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and denote hydrogen or methyl, but R.sup.1 and R.sup.2 do not simultaneously represent methyl,are prepared by a process wherein alkyldiphenyl ethers of the formula ##STR2## wherein R.sup.1 and R.sup.2 have the above-mentioned meaning are acetylated, the diacetyl compounds obtained, in aqueous-alcoholic solution or suspension, are converted to the corresponding dioximes with hydroxylamine, the dried dioximes are subjected to a Beckmann rearrangement and thereafter the diacetylaminoalkyldiphenyl ethers formed are hydrolyzed by means of aqueous mineral acids or alkali metal hydroxide solutions to give the diamines.The new diaminoalkyldiphenyl ethers are used in the preparation of dyestuffs and polyurethanes and serve as monomers for the preparation of polymers.
