Vanillin was reported to be readily soluble in alcohol (ethanol). The amount of vanillin is well in excess of the reported solubility at all working temperatures (cf. >> Among the more common perfume materials, Vanillin is one of the most tenacious odors known. [8] In 1874, the German scientists Ferdinand Tiemann and Wilhelm Haarmann deduced its chemical structure, at the same time finding a synthesis for vanillin from coniferin, a glucoside of isoeugenol found in pine bark. Vanillin was first synthesized from eugenol (found in oil of clove) in 187475, less than 20 years after it was first identified and isolated. Since Vanillyl alcohol is not soluble in water, it will begin to precipitate from solution during the slow acidification. (Method: FCC) The solubility of vanillin in ten different environmentally benign solvents namely water, ethanol, ethylene glycol (EG), ethyl acetate (EA), isopropanol (IPA), propylene glycol (PG), polyethylene glycol-400 (PEG-400), Transcutol, butanol-1 and butanol-2 was measured and correlated at T=(298318)K. The resulting experimental data were correlated with the modified Apelblat and Vant Hoff models. 6 0 obj Wood-based vanillin is produced by copper-catalyzed oxidation of the lignin structures in lignosulfonates under alkaline conditions[37] and is claimed by the manufacturing company to be preferred by their customers due to, among other reasons, its much lower carbon footprint than petrochemically synthesized vanillin.
