A new chiral 1,3-dioxane compound was synthesized by aldol condensation reaction in this paper. The reaction of cinnamic aldehyde with 2.1 equiv. of 2,2-bis(hydroxymethyl) butanol in N,N-dimethylformamide and cyclohexane, nanosolid superacid SO4(2-)/Fe2O3 was applied as catalyst, afforded the new chiral 1,3-dioxane compound(More)
A series of novel sodium (5-methyl-2-alkyl-1,3-dioxane-5-yl) carboxylate surfactants were synthesized using nanosolid superacid SO₄²⁻/Fe₂O₃as a catalyst and characterized by ¹H NMR, IR and elemental analysis. The critical micelle concentration (CMC) of surfactants was determined and the results showed that the CMC values were less than 2.0 x 10⁻³ mol/L.(More)
