Abstract: HOE 87/F 370K A process for the preparation of aminoaryl-.beta.-sulfatoethyl-sulfone compounds Aminoaryl-.beta.-sulfatoethylsulfone compounds, such as, for example 4-(.beta.-sulfatoethylsulfonyl)-aniline, can be prepared in a quick and easy manner from their corresponding .beta.-hydroxyethylsulfone compounds by sulfation by spraying a solution or suspension or paste of this aminoaryl-.beta.-hydroxyethylsulfone compound or the acylamino compound thereof in sulfuric acid or aqueous sulfuric acid into a hot inert gas stream of a convection dryer. In this procedure, the drying, esterification reaction and the hydrolysis of any acylamino group present takes place synchronously. The sulfato compound is preferably obtained in the form of granules.

Abstract: Styrylaryloxy ether sulfonates of the formula in which either R1 denotes styryl and simultaneously R2 and R3 are identical or different and denote hydrogen or styryl, or R1 and R2 are nonidentical and each denote methyl or styryl and simultaneously R3 denotes hydrogen or styryl, x denotes a number from 2 to 20, and M denotes an ammonium or alkali metal cation. These compounds are suitable as surfactant auxiliaries in oil recovery.

Abstract: of the disclosure 2-Methacrylamido-2-methylpropanephosphonic acid of the formula I I is prepared by reaction of 2-methylprop-1-ene-1-phosphonic acid or 2-methylprop-2-ene-1-phosphonic acid the methacrylonitrile in the presence of an equimolar amount of a strong acid. The compound is suitable as such or in the form of its salts as comonomer for the manufacture of copolymers, which are used inter alia as dyeing auxiliaries and as scale inhibitors.
