Specific features of the tandem hydroformylation–acetalization of a series of unsaturated compounds and polyols in the presence of a water-soluble catalytic system containing a rhodium catalyst precursor, sodium (triphenylphosphino)trisulfonate, and H2SO4 were investigated. The process parameters, including component ratio, temperature, and reaction time, were optimized using model substrates. With the suggested catalytic system, the conversion of unsaturated compounds to target products, acetals, reached 95%, and the catalytic system could be separated from the reaction products and repeatedly used without considerable loss of the activity. The acetal preparation procedure is versatile with respect to the raw materials. Batches of acetal mixtures were prepared by the suggested procedure from 1-octene and polyols, e.g., ethylene glycol, glycerol, and sorbitol.
