Abstract: PROCEDIMIENTO PARA LA PREPARACION DE COMPUESTOS AMINOARIL - SULFATOETISULFONICOS. COMPUESTOS AMINOARIL - 1-SULFATOETILSULFONICOS, TALES COMO, POR EJEMPLO, 4-( SULFATOETILSULFONIL)-ANILINA, SE PUEDEN PREPARAR POR SULFATACION, RAPIDA Y FACILMENTE, A PARTIR DE SUS CORRESPONDIENTES COMPUESTOS HIDROXIETILSULFONICOS, INCORPORANDO POR ROCIADO, DENTRO DE UNA CORRIENTE GASEOSA INERTE CALIENTE DE UN SECADOR POR CONVECCION, UNA SOLUCION, SUSPENSION O PASTA DE ESTE COMPUESTO AMINOARIL- -HIDROXIETILSULFONICO O DE SU COMPUESTO ACILAMINICO EN ACIDO SULFURICO O ACIDO SULFURICO ACUOSO. CON ELLO SE EFECTUAN SINCRONICAMENTE EL SECADO, LA REACCION DE ESTERIFICACION Y LA HIDROLISIS DE UN GRUPO ACILAMINO EVENTUALMENTE PRESENTE. EL COMPUESTO CON AGRUPACION SULFATO SE OBTIENE PREFERIBLEMENTE COMO GRANULADO.

Abstract: 2-Acrylamido-2-methylpropanephosphonic acid of the formula (I) is prepared by reaction of 2-methylprop-1-ene-1-phosphonic acid or 2-methylprop-2-ene-1-phosphonic acid with acrylonitrile 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 having improved properties.

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: Aminoaryl beta -sulfatoethyl sulfone compounds, such as, for example 4-( beta -sulfatoethylsulfonyl)-aniline, can be prepared in a quick and easy manner from their corresponding beta -hydroxyethyl sulfone compounds by sulfation by spraying a solution or suspension or paste of this aminoaryl beta -hydroxyethyl sulfone 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.
