Process for obtaining sulfonated paraffins containing more than 50% of polysulfonates, by weight, by causing essentially linear C.sub.12 -C.sub.20 paraffins to react with SO.sub.2 and O.sub.2, at a temperature comprised within the range of from 55 to 100.degree. C. and in the presence of a peroxide belonging to the class of peroxy dicarbonates.

Process for preparing sulfonated paraffins with a larger content of

Process for the catalytic hydroformylation of olefins in which an olefin is reacted with hydrogen and carbon monoxide, with the process being carried out by operating in a liquid, aqueous-organic reaction medium, in the presence of a water-soluble complex catalyst containing a metal active in the hydroformylation, wherein said aqueous-organic medium is in the form of a microemulsion consituted by an oil phase, an aqueous phase, a surfactant and a co-surfactant, with said oil phase constituting the external phase of said microemulsion, and said aqueous phase constituting the internal phase of said microemulsion.
