Optically pure (S) ethyl-2-hexan-1-ol (S)4 is prepared for the first time from (S) ethyl-2-hexanoic acid. Nucleophilic addition of sodium bisulfite on the bis [(S) ethyl-2-hexyl] maleate gives rise to an equimolar mixture of two opticallyactive sodium bis [(S) ethyl-2-hexyl] sulfosuccinates diastereoisomers. The criticalmicelleconcentration of these new opticallyactive surfactants is almost identical
