The invention relates to a method for synthesizing
azelaic acid through single
ionic liquid catalyzing
oleic acid. The method comprises the following steps:
oleic acid and a 1-(alpha-acid) methyl-3-methylimidazole
phosphotungstic acid ionic liquid catalyst are mixed, then a
hydrogen peroxide solution is added, the mixture is fully stirred, after the reaction, an oil layer is on the upper layer, a water lay is on the lower layer, and separation is easy; a separated aqueous phase is refrigerated and crystallized,
white powder is precipitated, and
azelaic acid solid is obtained through suction
filtration and
drying. According to the method, other chemical apparatuses are not required to be added in the whole reaction process, energy is saved, the
reaction speed is accelerated, the time is saved, and no large number of
organic solvent is required in the reaction, so that the method is green and environment-friendly. The method for synthesizing
azelaic acid through single
ionic liquid catalyzing
oleic acid has the advantages that the reaction yield is high, one step reaction process is simple, the
reaction system is easy to separated, the production cost is effectively reduced, and environment is protected.
