p-Toluenesulfonic acid → HCID 21532240, compound

Participants

Reaction Steps

Isobutyric acid (22.0 g, 0.25 mole), trans-2-nonen-1-ol (44.3 g, 0.25 mole), xylene (100 ml) and p-toluenesulfonic acid are heated to 145°C. The solution is refluxed for 5 minutes and 4.5 ml water is collected by distillation. The reaction mixture is cooled and first washed with water followed by 5% sodium carbonate. The washed solution is dried over sodium sulfate and distilled to yield 34.1 g of trans-2-nonenyl isobutyrate, b.p. 87° - 88°C/0.5 mm. An analytical sample is obtained for taste evaluation using gas chromatography.
