Branched alkyl sulfonate anionic surfactant and preparation process thereof

The invention discloses a branched alkyl sulfonate anionic surfactant and a preparation process thereof, and belongs to the field of fine chemical surfactants. The method comprises the steps of (1) conducting a esterification carboxyl-terminated reaction, specifically, catalyzing oleic acid or linoleic acid and fatty alcohol to be subjected to esterification reaction by adopting organic acid as acatalyst to prepare an alkyl oleate or alkyl linoleate compound; and (2) conducting a double bond addition sulfonation reaction, specifically, in the presence of the catalyst, carrying out sulfonationreaction with the alkyl oleate compound or the alkyl linoleate compound obtained in the step (1) by taking low-carbon alcohol and deionized water as solvents and sodium hydrogen sulfite as a sulfonation reagent to prepare the branched alkyl sulfonate anionic surfactant. The synthesized branched alkyl sulfonate anionic surfactant product can effectively reduce the surface tension of an aqueous solution, and is good in solubility, large in initial foaming amount, high in defoaming speed and excellent in surfactant performance. The method has the advantages of simple process operation, few sidereactions, energy saving and environmental protection.

Pyrazinium polyoxometalate tetrakaidecahedron-like crystals esterify oleic acid with equimolar methanol at room temperature

Ionic-liquid-modified polyoxometalate was prepared by self-assembly of Keggin-type heteropolyacids and sulfonated pyrazinium-IL, in which no template, surfactant, or organic solvent was used. The obtained ionic hybrid exhibits uniform morphology of cubic tetrakaidecahedron-like crystals and possesses a larger number of strong acid sites with narrower dispersion of acid strength than its analogues with similar chemical composition but different morphology. Catalytic activity tests reveal its high conversion, stable recycling, and good substrate compatibility for esterification of free fatty acids (FFA) with methanol into biodiesel at room temperature and over a wide range of molar ratios of methanol to FFA (10-50). Even under the ideal stoichiometric conditions (methanol:FFA = 1:1, a viscous solution), it converts 83% of oleic acid in 24 h. Morphology and performance are discussed, suggesting that the uniform crystals translate into high activity due to improved accessibility of the strong acid sites on the smooth external surface of the catalyst.
