    摘要: 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.

    摘要: 2,5-Dioxo-1,2-oxa-phospholanes of the formula (I) ##STR1## wherein R.sup.1 is an organic radical and R.sup.2 and R.sup.3 each also represents an organic radical or hydrogen, are prepared by reacting 2-haloformylethyl-phosphinic acid halides of the formula (II) ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are defined as in formula (I) and X means Cl or Br, preferably Cl, with an approximatey equimolar quantity of acrylic acid. The compounds (II) may also be produced in the reaction batch and in situ by reacting about equimolar quantities of a dihalophosphine of the formula (III) ##STR3## with an .alpha.,.beta.-unsaturated acid (IV)R.sup.4 -- OH (IV)In the formulae (III) and (IV) R.sup.1, R.sup.2, R.sup.3 and X are defined as indicated above.In the reaction there is formed, in addition to the compounds (I), practically exclusively .beta.-halopropionic acid and no free hydrogen halide.The phospholanes (I) are valuable flame retarding agents for plastics, intermediates, for example, for the synthesis of biocidals etc.
