Reaktionsschritte
A reactor equipped with a stirrer, reflux-condenser, thermometer and nitrogen gas inlet pipe was charged with 297 g of 2-tridecanone, 166 g of glycerol and a solvent amount of toluene, and following addition of p-toluenesulfonic acid as a catalyst, the dehydrative condensation reaction was carried out at the reflux temperature for 24 hours. The resulting crude product was washed with an aqueous solution of potassium carbonate and further with 3 portions of distilled water and finally purified by distillation under reduced pressure to provide 2-methyl-2-undecyl-4-hydroxymethyl-1,3-dioxolane.
