Abstract: A process for preparing alkanesulfonic acids from sulfur trioxide and an alkane, wherein sulfur trioxide, the alkane and dialkylsulfonoyi peroxide (DASP) react as components, characterized in that the following steps are performed: a) sulfur trioxide is charged in a high-pressure reactor in a condensed phase; b) a temperature of at least 25° C. is set; c) the gaseous alkane is introduced to the high-pressure reactor until a pressure of at least 10 bar is reached; d) dialkylsulfonoyi peroxide (DASP) is added; and e) after a duration of at least 5 hours, the produced alkanesulfonic acid is withdrawn.

Abstract: A compound of the formula (I) ALK-SO2—O—O—SO2OX, wherein ALK is a branched or unbranched alkyl group, especially a methyl, ethyl, propyl, butyl, isopropyl, isobutyl group, or a higher alkyl group, and X=hydrogen, zinc, aluminium, an alkali or alkaline earth metal.

Abstract: A process for the preparation of a polymer nanoparticle by a photoinduced emulsion polymerization includes preparing an emulsion comprising at least one surfactant, a dispersed phase and a continuous phase. The dispersed phase comprises at least one polymerizable monomer and the continuous phase comprises water and at least one photoinitiator. The at least one polymerizable monomer is polymerized by exposing the emulsion to an electromagnetic radiation having a wavelength so as to induce a generation of radicals from the at least one photoinitiator.
